Layouts and Plotting - Part 2

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

1. Describe lineweight and why it must be used in a plotted drawing.2. Describe the two methods of assigning lineweight in an AutoCAD drawing.

Drafting LessonLineweight

Industry standards have assigned a type and width to each line on a plotted drawing. Thismakes the drawings much easier to read and understand. It is important to follow thosestandards when plotting a drawing. The table below shows the basic linetypes you will beusing. They have an assigned weight and line width in both inches and millimeters.

Lineweights

AutoCAD Self-paced Learning Modules - AutoCAD 2D - Revised 2007-04-14

Assigning and displaying lineweight is not important when creating and editing the drawing,they are when you want to plot the drawing. Lineweights are normally plotted following acompany standard as shown in Figure 40-1. There are two methods of assigning lineweight toan object. They are Lineweight by color and Lineweight by object.

Assigning Lineweights by ColorAssigning the lineweight by color is the most popular method used in the CAD world. Using astandard chart, Figure 40-1, lineweights are assigned to each color. When the drawing isplotted, the plotter looks at the color of the object and plots it with the lineweight assigned tothat color. The color can be assigned by object or bylayer. The bylayer method is the mostpopular method and used extensively in the CAD world. Using this method, the lineweightcannot be displayed on the drawing in the graphics window.

Assigning Lineweights by ObjectLineweight can be assigned to all objects in the drawing so that when the drawing is plotted,the plotter simply plots the lineweight assigned to that object. The lineweights can be assignedto each object individually or bylayer. It is best to use bylayer as that is more of an industrystandard and much easier to use and manage.

Assigning Lineweights by Object

Step 1 Open drawingAutoCAD 2D Lab 23-2 that youcreated in Module 23.

Step 2 Using the SAVEAS command, savethe drawing with the name AutoCAD 2DWorkalong 40-1.

Step 3 Delete the titleblock, the titleblock text

and the border.Step 4 Using the PURGE command,purge layers Titleblock and TitleblockText.

Step 5 Create the necessary layers tomatch the list in Figure Step 5A. and thenfreeze the layers shown in the figure.

Authors Comments:Before you plot any drawing (layout), you must choosebetween plotting it with object lineweights, Figure Step 32A,or plot styles, Figure Step 32B. This can be set in the Plotoptions area in the Page Setup or Plot dialogue box. If youare setting plot by plot style, ensure the plot style color tableyou want to use is selected as shown in Figure Step 32C.

To copy an object(s) from model space to drawing space or vise versa, usethe principles of the copy and paste method that was covered in Module22. Remember you have to have model space as the working space toselect model objects and then change the working space to paper beforepasting the object(s). You can also copy and paste objects from paper

space to model space. The properties of the objects will be converted into the type ofspace they are being pasted into.

Geometry LessonSetting Custom Viewport Scales

When you are setting the scale for a viewport and thescale you want is not listed in the Standard scale list,you must calculate the scale factor you want.

The custom scale is simple to calculate. It is thescale factor or a ratio of the scale related to 1.For example, if you want the scale of:

1/4" -= 1'-0"

1/4"=1'-0" or 1/4"=12" or 1=48 or 1:48To get the scale factor in decimal format, divide:1 by 48 = 0.0208The custom scale would be set at 0.0208Here are some additional examples:

3/4" = 1'-0" or 3/4"=12" or 48 divided by 3 = 1:16 = 0.06253/4"=1" 1 divided by 0.75 = 1.333333331:1.51:51:751:500

1 divided by 0.75 = 0.66666661 divided by 5 = 0.20000001 divided by 75 = 0.0133333331 divided by 500 = 0.00200000

1:1500 1 divided by 1500 = 0.0006666615:1 15 divided by 1 = 15

Before you plot any drawing (layout), you must choose between plotting itwith object lineweights or with a plot style color table. This can be set in thePlot options area in the Page Setup or in the Plot dialogue box. If you aresetting plot by plot style, ensure the plot style table is set to the desiredtable.

When you are setting the custom scale property of a viewport, it isimportant that you first set the length units precision to 8 decimal places

40 - 15

using the UNITS command. For example, if you were setting the customscale of 1:1500 you would divide 1 by 1500 = 0.00066666. See what couldhappen below if you are using the wrong precision setting.

Custom Scale Displayed with 4 Decimals Places of Precision

The Same Custom Scale Displayedwith 8 Decimal Places of Precision

Correct Custom Scale

The Key Principles in Module 401. There are two methods of assigning lineweight to an object. They are Lineweight by

color and Lineweight by object.2. The display of the lineweights assigned to objects in the drawing is enabled or disabled

by toggling the LWT icon in the status bar.3. Before you plot any drawing, you must choose between plotting it with object lineweights

or with a plot style color table.4. When you are setting the custom scale for a viewport ensure you set the precision to 8

decimal place suing the UNITS command.
