Using the AutoCAD 2D Modules The CAD Guys Ltd. Copyright © 1993 - 2011 Module Introduction 1


AutoCAD 2DModule Introduction 1

Using the AutoCAD 2D Modules

Learning OutcomesWhen you have completed this module, you will be able to:

1 List the software and files required to complete the AutoCAD 2D Modules.2 Describe the AutoCAD Self-paced Learning Modules philosophy and explain how to read anduse the modules to learn how to apply the AutoCAD commands and features to draw 2D drawings.

The AutoCAD Software RequiredThe AutoCAD 2D Modules were written to be used with AutoCAD 2007, 2008, 2009, 2010, 2011and 2012 as well as AutoCAD LT 2007, 2008, 2009, 2010, 2011 and 2012. You must have accessto one of these software packages installed on your computer to complete the lab exercises in theAutoCAD 2D Modules.

Files Required for the AutoCAD 2D ModulesTo complete the lab exercises in this E-Book, you must have the four template files, thataccompany it, on your hard disk drive. Module 2 will teach you how to use them.

Philosophy of the AutoCAD Self-paced Learning ModulesThe AutoCAD Self-paced Learning Modules were written as a tool to guide and teach you to masterAutoCAD. No two students learn at the same pace, therefore the modules were written ascompetency-based bite-size pieces to allow each user to work at their own pace. They can be usedin correspondence, online and instructor-lead classes or by individuals teaching themselves to useAutoCAD in their own home or office.

Scope of the AutoCAD Self-paced Learning ModulesThe AutoCAD Self-paced Learning Modules are written in five parts, AutoCAD 2D, AutoCAD 3D,AutoCAD 2D Advanced, AutoCAD 3D Advanced and AutoLISP.

Suggested PerquisitesTo get the most from these modules, it is suggested that you have a working knowledge of theWindows operating system that is installed on the computer you are using to complete theAutoCAD 2D Modules. You must have at least the ability to create folders plus move, copy,rename and delete files using Windows Explorer.

The AutoCAD 2D ModulesThe AutoCAD 2D Modules were written in a very logical step-by-step order. Read and follow theinformation below to get the most from these modules.

AutoCAD Self-paced Learning Modules - AutoCAD 2D - Revised 2011-05-13Introduction 1 - 2


The ModulesThe modules are written in a precise order and contain the information that you require to learnAutoCAD 2D. Using AutoCAD is a never ending learning process and you will continue learninglong after completing these modules.

Do not skim through the modules. Read each page and ensure that you understand everything ineach module. Do not jump around inside the module or from module to module. Work your waymethodically through each module, page by page.

As you work your way through each module, learn and try to understand all the information itcontains. To ensure that you understand it, complete the lab exercises to prove it. Only when youunderstand everything in the module and can complete the lab exercises, in the specified time limit,should you go to the next module.

Each module may contain Must Know's, User Tips, Workalongs, Lessons, Key Principles and LabExercises.

Must Know'sMost modules contain user must know's. You must understand and retain each one of theseprinciples as you work your way through the modules. If you cannot understand any one of them, read back through the module. Do not go on until you fully understand it. For example:

(Do not attempt to understand this must know now, it is here for an example only.)

It is important when inserting the final line of aseries of lines to ensure your drawing is 100%accurate. On the object shown on the right,there are two correct ways to draw the last line. 1. C (to close) or 2.The absolute coordinate

1.75,4 The relative coordinate should never be used sinceyou can't be positive it will locate the end of the line at theexact location as the start point.

User TipsUser tips are in the modules to help you complete drawings faster and more efficiently. Theycontain tips, tricks and ways to use commands that will help you draw faster and increase yourproductivity. Study them and try to use the tips while doing the labs exercises. They are there tohelp you work smarter, not harder. For example:

(Do not attempt tp learn this user tip now, it is here for an example only.)

The function key F3 toggles the AutoSnap feature off and on. Although thereare other ways to do this, try to get into the habit of using F3 as it will greatlyimprove your drawing speed.

AutoCAD Self-paced Learning Modules - AutoCAD 2D - Revised 2011-05-13 Introduction 1 - 3


WorkalongsA workalong is an exercise that is completed by the user by working along with the modules,tutorial style, to complete a drawing using AutoCAD. Completing the workalongs in this mannerwill help you understand how the commands being taught in that module work by actually usingthem in AutoCAD. This will prepare you so that when you are completing the drawings in the labexercises, you should be able to complete them without any assistance. For example:

(Do not attempt this workalong now, it is here for an example only.)

Completed Drawing

Using the LINE CommandWorkalong and complete the steps below.

Step 1 Using the NEW command, start a new drawing using the template2D English.

Step 2 Save and name the drawing AutoCAD 2D Workalong 04-1 andunless otherwise instructed, save it in the folder: CAD Courses/AutoCAD2D/Lab Exercises.

Step 3 Enter the commands below to draw theobject shown. Keep in mind that you enter what isbolded, the italics are the author's comments and allthe rest are AutoCAD prompts.

Command: LINESpecify first point: 1.75,4

(Always start with an absolute coordinate. It must be an Xthen Y with a comma between them.)

Specify next point or [Undo]: @5,0(Then change to relative coordinates. Note the @ first,then X and Y.)

Specify next point or [Undo]: @0,2Specify next point or [Close/Undo]: @-2.5,0

(A negative coordinate is used since the line is going inthe negative X direction.)

Specify next point or [Close/Undo]: @0,1.5Specify next point or [Close/Undo]: @-1,1

(When both the X and Y coordinates have a value otherthen zero, the line will be inclined.)

Specify next point or [Close/Undo]: @-1.5,0Specify next point or [Close/Undo]: C

You can use a C or 1.75,4 to close the last line and returnto the first point.)

Command:



Geometry and Drafting LessonsSome modules contain drafting and/or geometry lessons. They are included to teach students whodo not have any previous drafting/design knowledge or experience. They may also be handy fordrafters or designers who need a refresher lesson.

If you already know the theory in the lesson, skip it and go on to the next topic in the module. Ifyou do not know it, study it. These lessons are not part of the course and you will not be tested onthem. However, knowing the theory taught in them will help you complete the lab exercises. Forexample:

(Do not attempt to learn this geometry lesson now, it is here for an example only.)

Figure 7-1Circle Geometry

Geometry LessonCircles

A circle is defined as a closed curve in which all points are the same distance from its centerpoint. The center point is a single XY coordinate. Study the drawings below for a completedescription of the characteristics of a circle.



Key PrinciplesEach module contains a list of key principles. The key principles are principles that you shouldhave learned and understand in that module. It is important that you understand each one of theseprinciples as you will be required to use them in future AutoCAD work. For example:

(Do not attempt to learn the key principles now, it is here for an example only.)

The Key Principles in Module 41 The @ symbol means "The last absolute coordinate location". 2 To close the last line of a series of lines, use either C (Close) or the absolute coordinate ofthe first point.3 To delete existing objects on a drawing, you can either use the ERASE command or theDelete key on the keyboard.4 Objects can either be selected before or after the command is entered.

Lab ExercisesAll lab exercises have a time limit allocated to them. To complete the lab exercise in the specifiedtime limit, you must be able to complete the drawing, check it for accuracy and make anycorrections. If you cannot do this in the time allowed, redo the entire lab exercise. It is your way ofproving that you have mastered the module.

Almost all modules contain at least two lab exercises. If you are in a classroom situation where youdo not have a lot of time, only complete the first lab exercise in each module. It is stronglysuggested, however, that you complete all lab exercises in each module, if possible.

Checking the Accuracy of Your DrawingsAlmost all lab exercises will have a key provided that you can use to check your drawing foraccuracy. You will be taught how to do this in Module 3.

Competency TestsEvery fifth module is a timed competency test module. A competency test module has multiplechoice questions and a comprehensive lab exercise to test your mastery of the last four modulesthat you just completed. There is no key supplied with this module since it is meant to be checkedby your instructor. If there are any parts of this module that you have trouble completing or youcannot complete in the time allowed, you should go back and reread the module or modulescontaining the information that you are having trouble with. If necessary, redo any lab exercises tohelp you learn the material.



Conventions and Symbols Used in the AutoCAD 2D ModulesThe following conventions and symbols are used in the modules to help you understand thematerial.

Words in Red ItalicsWords in red italics are new terms being introduced in that module. They will only appear in italicsthe first time they are mentioned and will be defined. For example:

The current layer is the layer that AutoCAD will place all newly created drawing objects on.

Words and Numbers that are in Bold FontIn workalongs, all words and numbers in bold font are input by you. It is your way of knowing if it isa user input or an AutoCAD response. For example:


(Always start with an absolute coordinate. It must be X then Y with comma between them.)Specify next point or [Undo]: @5,0Command:

Command NamesCommand names are always in uppercase. For example:

To construct a fillet, use the FILLET command. The rule of thumb to follow is "If the arc you aredrawing is tangent to both objects it is connecting to, use the FILLET command to insert it”.

Picking Objects or Locations on the Drawing To help you understand when an object or a location is picked, the modules use the letter ?P”along with a number that indicates which pick it is in the sequence. For example:

(Do not attempt this workalong now, it is here for an example only.)

Command: FILLETCurrent settings: Mode = TRIM, Radius = 0.6000Select first object or [Polyline/Radius/Trim]: RSpecify fillet radius <0.6000>: .25

(Set the radius for the fillet.)Select first object or [Polyline/Radius/Trim]: P1Select second object: P2

(Pick the two lines to insert the fillet between.)Command: FILLETCurrent settings: Mode = TRIM, Radius = 0.2500Select first object or [Polyline/Radius/Trim]: P3Select second object: P4Command:



Author's CommentsA comment by the author, to help explain what is happening in a command, is in green italics,inside brackets. For example:

(Do not attempt these command now, they are here for an example only.)

Specify first point: 1.75,4(Always start with an absolute coordinate. It must be X then Y with a comma between them.)

Specify next point or [Undo]: @5,0(Then change to relative coordinates. Note the @ first, then X and Y.)


(Note the negative coordinate since we are going in the negative X direction.)Specify next point or [Close/Undo]: @0,1.5Specify next point or [Close/Undo]: C

(You can use a C to close the last line and return to the first point.)Command:

There are also author's comments in the workalong or lab exercise to help you understand aprinciple or to complete a task. For example:

Author's Comments: The Insertion scale for the all lab exercises in the AutoCAD 2D Modules isshown in the Units column as shown in the Figure 3-1.

The Key Principles in Module Introduction 11 To complete the lab exercises in this E-Book, you must have the four template files, thataccompany it, on your hard disk drive. 2 Do not skim through the modules. You must read and understand everything in each module. Do not jump around inside the module or from module to module. Work your way methodicallythrough each module, page by page.3 The AutoCAD Self-paced Learning Modules were written as competency-based bite-size piecesto allow you to work at your own pace and learn to use AutoCAD. Do not go onto the next moduleuntil you understand the module you are working on and have completed the lab exercise(s). 4 All lab exercises have a time limit allocated to them. To complete the lab exercise in thespecified time limit, you must be able to complete the drawing, check it for accuracy and make anycorrections. If you cannot do this in the time allowed, redo the entire lab exercise. It is your way ofproving that you have mastered the module.

Do not memorized AutoCAD - UNDERSTAND it.

Figure 1-3The Pickbox

CrosshairsThe crosshairs indicates the user's current location. Think of it as the point of the pencil. It isused extensively while working in AutoCAD. It is one of the most important tools.

PickboxThe pickbox, is a small square located at the intersection of the crosshairs as shownin Figure 1-3. It is used to pick drawing objects. Its size can be adjusted using theOptions dialogue box as shown in Module Introduction 2.

Figure 1-2AutoCAD's Graphic Window - AutoCAD 2009-2012

The size of the crosshairs can be changed. For the AutoCAD 2D Modules andmost other AutoCAD work, it is best to have them full screen as shown in Figure1-1 and Figure 1-2.

Figure 1-5Model and Layout Tabs

Status BarThe status bar, Figure 1-4, is positioned across the bottom of the Graphic window and becomes avery important part of the users day-to-day AutoCAD work.

The coordinate location or the XYZ coordinates of the current location of the crosshairs isdisplayed on the left side of the status bar. The coordinate location display can be enabled ordisabled by clicking it with the left mouse button. Toggle buttons for ten of AutoCAD's features arelocated immediately to the right of the coordinate display. Most of these features will be taught inthe AutoCAD 2D Modules.

Model and Layout TabsThe Model and Layout tabs, Figure 1-5, are used to enable the display of the model or a layout. Itwill be discussed further in Module 18.

Command Line WindowThe Command Line window is used to enter keyboard commands and user inputs. It is also usedby AutoCAD to output information to the user. See Figure 1-6. It is one of the ways that the usercommunicates with AutoCAD and is a very important way for AutoCAD to communicate with theuser. It is important for the users to watch this window closely as they is drawing. It is used byAutoCAD to ask for information, instruct the user to what data it requires or display answers to userinquiries. It will be discussed in much greater detail in Module 2.

Scroll BarsThe scroll bars work exactly the same as the scroll bars in other software programs. They can beused to scroll the drawing up, down, left or right. There is a much better way to scroll around the drawing as shown in Module 9. One important use of the scroll bar is that they indicate the overallsize of the current drawing and the current viewing position on the drawing.

Figure 1-7AutoCAD’s Pull-Down and Toolbar Menus

AutoCAD's MenusAutoCAD has many different menus that allow the user to communicate with it. The most usefulones are the pull-down and the toolbar menus as shown in Figure 1-7.

Pull-Down MenuThe pull-down menu Is located across the top of the Graphicwindow. When an item on the menu is clicked, with the left mousebutton, the menu will pull down as shown in Figure 1-8. In thisfigure, the menu item Tools was clicked.

A Pull-Down Menu FlyoutIf an item on the pull-down menu has a small solidtriangle at the end, it has a flyout menu associatedwith it. Place the graphic cursor on the triangle toforce the flyout menu to display as shown inFigure 1-9.

Figure 1-9Flyout Menu



Figure 1-13Toolbar Menu List

Figure 1-10A Toolbar Menu -

2007-2008 Figure 1-11A Toolbar Menu - Showing a Tooltip

Toolbar MenusThe toolbar menus are a series of icons that are located on acollection of menu bars. See Figure 1-10 and 1-12. The display ofeach toolbar can be enabled or disabled at the user's discretion. Ifthey were all displayed at the same time, they would virtually fill theGraphic window. Therefore, their display must be enabled ordisabled, as required, by the current operation in the drawing. Toolbars can float inside the Graphic window or they can bedocked along any one of the four sides. If the graphic cursor isplaced on an icon in a toolbar, a tooltip will display indicating thepurpose of the icon as shown in Figure 1-11. While the AutoCAD2009-2012 toolbars have a slight different look, Figure 1-12, theywork the same as in AutoCAD 2007-2008. AutoCAD allowstoolbars to be created or existing toolbar to be edited. This istaught in the AutoCAD 2D Advanced Modules.

Docked and Floating Toolbar MenusIn Figure 1-7, the toolbars across the top of the graphic window aredocked and the ones in the center are floating. To dock a toolbar,drag it by clicking and holding the left mouse button on the titlestrip along the top of the menu. Drag it to any one of the four sidesand release the mouse button. It will automatically dock. Toundock it, do the opposite.

Displaying Toolbar MenusTo enable or disable the display of toolbar menus, place the graphic cursor on any icon on a currently displayed toolbar and right-click the mouse. A list of all the available toolbar menus willdisplay as shown in Figure 1-13. Click the name on the toolbar menu to toggle its display. Acheckmark beside the toolbar's name indicates that its display is currently enabled.

Another method of disabling the display of a toolbar menu is to click the X in the top right handcorner of the toolbar.

2012 Toolbar



Figure 1-14A Dialogue Box

Dialogue BoxesAutoCAD uses many different dialogue boxesto speed the drawing process. A dialogue boxis an effective and efficient method forAutoCAD to allow the user to modify or enterinformation, settings and sizes. While adialogue box is open, no other work can bedone on the current drawing. It must be closed before continuing to the next command. Atypical dialogue box is shown in Figure 1-14.

When a pull-down item has 3 dots after theword, Figure 1-15, it indicates that, whenclicked, it will open a dialogue box or a window.

WindowsAutoCAD uses many different windows to speed thedrawing process. Compared to a dialogue box, a windowis a more efficient method for AutoCAD and the user tocommunicate. Windows are interactive and display dataand information about the current drawing or objects inthat drawing as the drawing is being worked on. Unlike adialogue box, a window can remain on the screen as theuser is working on the drawing and updatesautomatically. A typical window is shown in Figure 1-16.

Figure 1-18AutoCAD’s Text Window

The MouseAutoCAD is programed to use the three buttons on a mouse as follows:

Left Button: This is the pick button. Use it to pick objects, pick menu items or to selectlocations on the drawing.

Middle Button: The middle button, or wheel, is used to zoom and pan aroundthe drawing. This will be discussed in detail in Module 9.

Right Button: The right button has two uses. If pressed and releasedquickly, it repeats the last command. If pressed and held in, itdisplays the cursor menu. See Figure 1-17. The cursormenu display differently depending on the current or lastcommand entered. It can be a very helpful menu once theuser get used to working with it.

AutoCAD's Text WindowAutoCAD's Text window, Figure 1-18, displays all of the commands that were entered by the userand AutoCAD's responses to those command for the duration the current drawing is active. This isone way for the user to look back at the commands, user input and AutoCAD's responses. Totoggle the display of the text window, press F2.

Getting Started


1 Describe a drawing, a drawing template, drawing names and drawing file extensions.2 Apply the commands NEW, QSAVE, OPEN, SAVEAS and CLOSE to start a new drawing,name and save the current drawing into a specified folder, open a filed drawing, save the currentdrawing with a different name and close a drawing.3 Describe an AutoCAD command including option prompts and defaults.4 Describe how to execute, repeat and abort commands.

An AutoCAD DrawingAn AutoCAD drawing is a database file containing graphical and non-graphical data and must havethe extension .dwg. To be able to do anything in AutoCAD, there must be at least one drawingopen. Multiple drawings can be opened at the same time and the user can switch between them,as required. Only one drawing can be current at a time. The current drawing is the drawingcurrently being affected by the commands entered by the user. It is sometimes called the activedrawing.

Drawing TemplatesA drawing template is a drawing file that may contain layouts, defaults, blocks and standards set bythe creator of the template and used to start a new drawing. A template files must be used to starta new drawing. A template drawing is simply an AutoCAD drawing saved as a template file. AutoCAD assigns it the file extension name .dwt. Creating template files is taught in the AutoCAD2D Advanced eBook.

Drawing Templates for the AutoCAD 2D eBookThere are four drawing templates that are animportant part of the AutoCAD 2D Modules. One ofthese templates must be used to start all newdrawings when working on a workalongs or labexercises in the modules.

These template are supplied to each user of theAutoCAD 2D eBook and should be saved in theTemplates folder as shown in Figure 2-1. Figure 2-1

Figure 2-2AutoCAD File Extension Names

AutoCAD File ExtensionsAutoCAD uses many different fileextension names. The file extensionsused in the AutoCAD 2D Modules are.dwg, .dwt, and .bak. See Figure 2-2. The other AutoCAD file extensions aretaught in the AutoCAD 2D AdvancedModules.

AutoCAD creates a .bak file when apreviously saved drawing is saved. When the drawing is saved, AutoCAD changes the extensionof the existing drawing from .dwg to .bak and then creates a new file with the extension .dwg. If adrawing file ever gets lost or corrupted, the extension name of the .bak file can be changed to .dwgand opened in AutoCAD.

The Drawing NameEach drawing should be assigned a unique name. It is important to name a new drawing as soonas possible after it has been started. Getting into this habit will save many hours of searching thedisk drive looking for existing drawings or redrawing lost drawings.

AutoCAD Command: CLOSEThe CLOSE command is used to close the currentdrawing.

Shortcut: none

When you save an AutoCAD drawing for the first time it adds the extension .dwg tothe drawing's name. When you save a drawing that was previously saved, AutoCAD changes the extension of the existing drawing file to .bak and creates anew drawing file with the extension .dwg. If a drawing file ever gets lost or

corrupted, the extension name of the .bak file can be changed to .dwg and opened in AutoCAD.



Creating, Naming, Saving, Opening and Closing DrawingsStep 1 Start AutoCAD. Your graphic screen should be similar to the figure. (Figure Step 1)

Step 2 Enter the NEW command. It will open the Select template dialogue box. Select thetemplate 2D English and click Open (Figure Step 2)

Author's Comments: If you do NOT see the four templates filesshown in Figure Step 2, you must go back and redo Steps 10 toStep 13 in the module AutoCAD 2D Introduction 2. Do notcontinue in this module until your dialogue box matches FigureStep 2. If you have trouble getting it to match, email yourinstructor for help.

Step 3 Note the drawing name Drawing1.dwg displays on thetop bar of the graphic window. (Figure Step 3)

Author's Comments: This is the drawing name that wasassigned by AutoCAD when you started the drawing with theNEW command. Don't be concerned if the number at the end ofthe drawing name is different.

Step 4 Enter the QSAVE command to open the Save DrawingAs dialogue box. Find and select the folder CAD Courses. Under it, select AutoCAD 2D and under that, Lab Exercise.(Figure Step 4A, 4B and 4C)

AutoCAD CommandsMost work in AutoCAD consists of the userissuing instructions. Those instructions arecalled commands. Commands are usually entered using the command line window, apull-down menu or a toolbar menu. Figure2-3 shows the LINE command beingentered using all three methods.

Regardless of the way that a command is entered by the user, AutoCAD does not know or care where the command wasinitiated. To AutoCAD, all commands lookalike, therefore, the user can choose whichmethod to use. There is no right or wrongmethod to enter a command. Throughoutthe AutoCAD 2D Modules, the differentmethods of entering commands is shownand the user can decided which method touse.

Executing CommandsSome menu items execute commands automatically but most of the time it is up to the user toexecute the command. Executing a command is the users way of telling AutoCAD that he/she isfinished and AutoCAD should do what was commanded. A command can be executed by eitherpressing the Enter key or the Space Bar on the keyboard.

Repeating the Last CommandAutoCAD can be very repetitive. To work faster, the last command that was executed, can berepeated by pressing the Enter key, the Space bar or by right clicking the mouse.

Option PromptsAfter most commands are executed, AutoCADwill respond with an option prompt. An optionprompt is AutoCAD asking the user a questionin response to a command or requesting someuser input. Figure 2-4 shows three commandsand the option prompts returned by each one. User input is in bold. In the LINE command, AutoCAD's option prompt is Specify first pointand the user responds 2,2. AutoCAD thenasks Specify next point or [Undo]:. It isimportant for the user to watch the CommandLine window to see what AutoCAD is askingfrom him or her next.



Command: CIRCLESpecify center point for circle or [3P/2P/Ttr (tan tan radius)]:

(The default is Specify center point for circle)Specify radius of circle or [Diameter] <3.0000>:

(The default is radius of circle, size 3.0000)Command:

Command: FILLETCurrent settings: Mode = TRIM, Radius = 0.2500

(The default Mode is TRIM and Radius is 0.2500)Select first object or [Polyline/Radius/Trim]:

(The default is Select first object)

Command: TEXTCurrent text style: "Standard" Text height: 0.2000

(The default text style is Standard and height 0.2000)Specify start point of text or [Justify/Style]:

(The default is Specify start point of text)Specify height <0.2000>:

(The default height is 0.2000)Specify rotation angle of text <0>:

(The default rotation angle is 0)Text:

Figure 2-5AutoCAD Defaults

DefaultsAutoCAD sets defaults for almosteverything. A default is the valueAutoCAD uses, if the user does notsupply one. Defaults are enclosedinside angle brackets "< >". If theuser wants to use the default value,he or she simply responds bypressing the Enter key or the Spacebar. See Figure 2-5.

Command OptionsCommand options are selectionsthat the user can choose from tochange the default. Commandoptions are enclosed inside "[ ]" asshown in Figure 2-5. An example ofthe defaults and options for theCIRCLE command are as follows:

Specify center point for circle or[3P/2P/Ttr (tan tan radius)]:

Specify center point for circle - is thedefault.

[3P/2P/Ttr (tan tan radius)] - are theoptions.

Cancelling or Aborting a CommandCommands can be cancelled or aborted by pressing the Esc key on the keyboard. Sometimes itmust be pressed twice to completely abort the command and return to the Command: prompt.

The Enter key or the Space bar are used to execute commands. If either one ispressed when there is no active command, AutoCAD will repeat the last command.Right clicking the mouse will produce the same results..

AutoCAD's option prompts are a combination of upper and lower case letters. To help you work faster, only enter the uppercase character(s) when entering anoption. For example:

Command: LENGTHEN Select an object or [Delta/Percent/Total/DYnamic]: (For Delta enter D, for Percent enter P, for Total enter T and for DYnamic enter DY.)

Checking the Accuracy of Drawings


1 Describe how lab exercise drawings in the AutoCAD 2D Modules are checked for accuracy.

Checking the Accuracy of DrawingsIt is extremely important in AutoCAD to draw all drawings with 100% accuracy. This cannot bestressed strongly enough as it is essential that each object in the drawing is positioned and sizedperfectly. Most lab exercises in the AutoCAD 2D Modules can be checked for accuracy byoverlaying the drawing with a key. This helps the beginner to know when the drawings areaccurate and will display any objects on the drawing that are drawn incorrectly. As users becomemore experienced drawing in AutoCAD, they will not require the use of keys.

Figure Step 3

Author's Comments: This is just a demo, therefore, there is nothing for you to do but learn theprocess. You will be checking your first drawing for accuracy in Module 4.

Step 13 This will insert a magenta colored overlay key on your drawing. If you see doubleobjects or places where your objects and the magenta objects don't match, your drawing isinaccurate. If you only see one object, even though it may share the colors magenta and red, yourdrawing is accurate. If your drawing is incorrect, remove the key and correct your drawing. Recheck it with the key. When it matches the key, go on to the next lab exercise or module. Module 5 will teach you how to remove the key. (Figure Step 13)

Step 14 Save and close the drawing.

Figure Step 13

The Key Principles in Module 31 AutoCAD drawings must be drawn 100% accurate. 2 Most lab exercise drawings in the AutoCAD 2D eBook can be checked for accuracy using akey.3 The name of the key that you select to check your drawing is always the name of the currentdrawing for the lab exercise.4 Your drawing is not accurate if the magenta objects in the key do not match your drawing. Ifyou only see one object, either magenta or red, your drawing is 100% accurate.

Drawing lines Using Cartesian Coordinates The CAD Guys Ltd. Copyright © 1993 - 2011 Module 4


AutoCAD 2DModule 4

Drawing Lines Using Cartesian Coordinates

Learning Outcomes:When you have completed this module, you will be able to:

1 Describe the Cartesian Coordinate System using absolute and relative coordinates. 2 Apply the LINE command to draw lines using the Cartesian Coordinate System with bothabsolute and relative coordinates.

Figure 4-1The Cartesian Coordinate System

The Cartesian Coordinate SystemTo accurately draw an AutoCAD 2-Dimensional (2D) drawing, coordinate locations must be enteredas XY coordinates. These XY coordinates are based on the Cartesian Coordinate System.

The Cartesian Coordinate Systemconsists of two numbered linescrossing perpendicular to one anotherat their zero values. The horizontalaxis is called the X-axis and thevertical axis is called the Y-axis. SeeFigure 4-1. A coordinate value isassigned to each location on theplane. Each coordinate valueconsists of a pair of numbers, the firstof which is the X-coordinate and thesecond is the Y-coordinate, writtenX,Y. For example, X2,Y4 is alocation 2 units to the right and 4 unitsup from X0,Y0 or 0,0.

Cartesian coordinates can be enteredinto AutoCAD as either absolute orrelative coordinates.

Absolute Cartesian CoordinatesAbsolute Cartesian Coordinates arealways referenced to the absoluteorigin 0,0. For example: 3,4.

Relative Cartesian CoordinatesRelative Cartesian Coordinates are incremental to the lastpoint. To indicate to AutoCAD that thecoordinate being entered is relative, an @ is entered before the coordinate value. For example:@2,6 which means "from the lastpoint go 2 units in the positive X and 6 units in the positive Y".

AutoCAD Command: LINEThe LINE command is used to draw lines.

Shortcut: L

2009-2012

Drawing Lines Using Cartesian Coordinates - Part 1 Step 1 Using the NEW command, start a new drawing using the template 2DEnglish.

Step 2 Save and name the drawing AutoCAD 2D Workalong 04-1. Save it in the folder: CAD Courses/AutoCAD 2D/Lab Exercises

Step 3 Enter the LINE command as shown below todraw the object shown in the dimensioned drawing. Keep in mind that you enter what is bolded, the italicsare the Author's Comments and the remainder areAutoCAD prompts.


(Always start with an absolute coordinate. It must be an Xthen Y with a comma between them.)

Specify next point or [Undo]: @5,0(Then change to relative coordinates. Note the @ first,then X and Y.)


(A negative coordinate is used since the line is going in thenegative X direction.)

Specify next point or [Close/Undo]: @0,1.5Specify next point or [Close/Undo]: @-1,1

(When both the X and Y coordinates have a value other then zero, the line will be inclined.)Specify next point or [Close/Undo]: @-1.5,0Specify next point or [Close/Undo]: C

You can use a C or 1.75,4 to close the last line and return to the first point.)Command:

Author's Comments: Rather then just entering the coordinate values, try to understand thevalues you are entering by studying the dimensioned drawing.

Step 4 Your drawing should match the figure. (Figure Step 4)

Author's Comments: If you have trouble drawing this object thefirst try, do not be concerned. Start it over again, from scratch, untilyou can complete it. The more practice you get drawing, the easierit will get.


Figure Step 4

When you start a drawing, the first XY location is always specified using anabsolute coordinate. After that, relative coordinates are used. It would be toodifficult to calculate all coordinates as absolute.

Author's Comments: If you have trouble drawing thisobject the first try, do not be concerned. Start it overagain, from scratch, until you can complete it. The morepractice you get drawing, the easier it will get.


Figure Step 4

To ensure that your drawing is 100%accurate, how the final line, of a series oflines, is drawn is important. On the objectshown on the right, there are two correct waysto draw the last line.

1. C (to close) or2. The absolute coordinate 1.75,4.

A relative coordinate should never be used since you can notbe positive the end of the line will be located at the exactcoordinates as the start point.



When entering decimal numbers and the number ends in a zero, for example 4.0, enter the number up to the zero. In this case, 4. If the number to be entered is3.6700, all that has to be entered is 3.67. AutoCAD will automatically enter thezeros to the value.

Deleting ObjectsTo delete existing drawing objects, either use the ERASE command or the Delete key on thekeyboard.

Using the ERASE CommandWhen deleting drawing objects using the ERASE command, the drawing objects can either beselected before or after the command is entered. If the command is entered before selecting theobjects, they are selected when prompted by the Select Object prompt as shown below. If theobjects are selected before entering the ERASE command, there is not prompt.

Command: ERASESelect Object:

Using the Delete KeyWhen deleting objects using the Delete key, select the object or objects before pressing the key.

Layers


1 Describe AutoCAD's layering system2 Apply the LAYER command to create, toggle on/off, thaw/freeze, lock/unlock, select color andset the current layer for the active drawing.

Figure 5-1Points and Lines

Geometry LessonPoints and Lines

A point is defined as a single XY coordinate. It does not have width, height or depth. A line is theshortest distance between two XY locations. Lines can be horizontal, vertical or inclined. Linesthat are the same distance apart are called parallel lines. Perpendicular lines are at right angles toeach other or 90 degrees apart. See Figure 5-1.



Figure 5-2Layers Seen as Overlays

Figure 5-3Stacked Layers

LayersAutoCAD's layering system is one of the mostimportant features available in AutoCAD. Layersallow the user to organize, segregate, control thevisibility and manage plotting of the drawing.

Think of layering as being able to draw ontransparent overlays with each overlay containingrelevant or grouped objects, see Figure 5-2. Whenall of the overlays are stacked together, see Figure5-3, the user can see and work with all of them. Atany time, during the drawing process, the layer'svisibly can be controlled during the drawing andplotting process.

There is no limit to the number of layers that can be created ineach AutoCAD drawing. As layers are created, they can benamed by the user or allow AutoCAD to automatically namethem. A color, linetype, lineweight, and plot style can also beassigned. In this module, only naming and assigning a color willbe taught.

In addition to what was just discussed, the visibility of each layercan be controlled by toggling layers off or on and freezing orthawing them. Layer can also be locked to prevent objects onthem from being modified.

AutoCAD's Special LayerAutoCAD has a special layer, named 0 (the number zero). Each new drawing created in AutoCADwill automatically contain this layer. It cannot be deleted or renamed. Layer 0 will be discussedfurther in future modules.

The Current LayerThe current layer is the layer that AutoCAD will place all newly created drawing objects on. Onelayer must be current at all times. The current layer can be turned off but never frozen. The currentlayer can be changed at any time.



2007-2008

Figure 5-4Properties Set Bylayer

ByLayerAutoCAD assigns the color, linetype, and lineweight properties to drawing objects either ByLayer orByObject. In the AutoCAD 2D Modules, all work is done ByLayer. An easy way for users to checkif they are working ByLayer is to look at the first three boxes in Properties toolbar as shown inFigure 5-4.

The three properties boxes should always display the words ByLayer as shown in the figure.

Simply, ByLayer means that when an object is inserted into the drawing or an existing object isregenerated, it looks in the drawing’s data base to see what color, linetype and lineweight it shoulddisplay. If it is set ByLayer, it will then check what layer it is located on and displays the color,linetype and lineweight assigned to that layer. Most companies require the color, linetype andlineweight properties of their drawings to be drawn Bylayer.

It is important to know the different between a layer that is Off and a layer that is Frozen. A layerthat is Off does NOT display but WILL regenerate. A layer that is Frozen does NOT display andwill NOT regenerate. The importance of this will become apparent in future AutoCAD 2D Modules.

On/Off: Toggles the drawing objects on the layer on or off. In other words, visible ornot visible.

Freeze/Thaw: Toggles the layer to be frozen or thawed. The drawing objects on a frozenlayer are not visible and do not regenerate. The objects on a thawed layerare visible and will regenerate.

Lock/Unlock: Toggles the layer locked or unlocked. Drawing objects on a locked layerare visible but cannot be modified or deleted. Drawing objects on anunlocked layer are visible and can be modified.

Color: Sets the color for the layer. All drawing objects on the layer, with theproperty ByLayer, will display the color assigned to the layer.

Unless otherwise instructed while working in theAutoCAD 2D Modules, select the colors from theStandard Color Palette as shown in the figure onthe right. The colors included in this palette are

the common colors and are named. The colors from the chartabove it are numbered colors and should not be used unlessinstructed to do so in a lab exercise. White and black are thesame color to AutoCAD. White will display black on a white background and black will displaywhite on a black background.



Author's Comments: Once you havecreated the layers in the drawing, you can usethe Layer toolbar menu, Figure 5-5, to changethe current layer or to toggle the layerproperties. This is much faster then using theLayer Properties Manager window or thedialogue box. The Layer toolbar should always be enabled and located across the top of theGraphic window.

Step 10 Take note how the current layer will displayin the Layer toolbar. In this case, it is Object.(Figure Step 10)

Step 11 Pull down the layer list by clicking thesmall triangle on the right side. Change the currentlayer to 0 by clicking the layer name.(Figure Step 11A and 11B)

Step 12 Pull down the layer list again and this timetoggle the layer properties so that all four layer areon, thawed and unlocked. (Figure Step 12)

Step 13 Change the current layer to Object.(Figure Step 13)

AutoCAD has a special layer named 0 (the number zero). Each new drawingcreated in AutoCAD will contain layer 0. It cannot be deleted or renamed. It hasother special attributes as you will see in future modules.

It is important to know the different between a layer that is Off and a layer that is Frozen. A layer that is Off does NOT display but WILL regenerate. A layer that isFrozen will NOT display and will NOT regenerate. This is important as you willlearn as you work your way through the modules.



To quickly set the current layer in the Layer Property Managers window ordialogue box, double click the Status icon beside the layer name as shown in thefigures below.

AutoCAD does not know the difference between the colors black and white. On ablack background, the color black will display white and on a white background, thecolor white will display black.

Key Off Key On

In Module 3, you were shown how to insert a key onto your drawing to check it'saccuracy. The key resides on the layer Key. If you are required to work on yourdrawing after you inserted the key, toggle layer Key off. To re-check your drawingafter you finish the editing, toggle layer Key on as shown in the figures below.

The current layer is the layer that any newly inserted object will reside on. It isimportant to always be aware of what the current layer is before inserting objects. The current layer cannot be frozen.

The Key Principles in Module 51 AutoCAD's layering system is one of the most important features to the AutoCAD user. Layersallow the user to organize, segregate, control the visibility, and manage plotting of the drawing. They are use extensively by companies using AutoCAD.2 The current layer is the layer that any newly inserted object will reside on. 3 AutoCAD has a special layer named 0 (the number zero). Each new drawing created inAutoCAD will automatically contain layer 0. It cannot be renamed or deleted. 4 A layer that is Off, does NOT display but WILL regenerate. A layer that is frozen does NOTdisplay and will NOT regenerate. 5 A current layer can be turned off but not frozen.
