INTRODUCTION

Welcome to the AutoCAD2011 .We have work diligently to bring you a book that takes youthrough the core features and functionality of AutoCAD2011 from the both the design anddocumentation perspectives.

The development team has been listening to the needs of users and has delivered tools andfeatures in this release that have been desired by many from the beginning. We now havetools that make drafting much easier than before, new control of engineering systemsdisplay, work sharing enhancement, and many other new features.

The book is written in five times, the first of which covers general functionality that is usefulfor all disciplines. You will find suggestions throughout the book for including features andcomponents in your project templates. The first part does not cover every pick and clickavailable in the software; it approaches the use of CAD from best-practices standpoint,which we hope will inspire to think about ways to make AutoCAD2011 work best for you.Any topics not covered were not omitted to imply that they are unimportant but simplybecause you can find information about these features in documentation provided byAutodesk and in the

you can create a series of contiguous line segments. Each segment is a line object that can

be edited separately.

Close :

Ends the last line segment at the beginning of the first line segment, which forms a closed

loop of line segments. You can use Close after you have drawn a series of two or more

segments.

Undo: Erases the most recent segment of a line sequence.

Entering u more than once backtracks through line segments in the order you created them.

ERASE : Removes objects from a drawing.

Select the objects to erase, right-click in the drawing area, and click Erase.

Command: ERASE (E)

Select objects: ALL

10 found

UNDO : Reverses the effect of commands. (CTRL+Z)

Undoes the specified number of preceding operations. The effect is the same as entering umultiple times.

REDO : Reverses the effects of previous UNDO or U command. (CTRL+Y)

With no commands active and no objects selected, right-click in the drawing area and choose Redo.

OOPS Sometimes you unintentionally erase some object from the screen andwhen you discover the error.you want to correct it by restoring the erased object.The

oops command is used in such situations.

LINE THREE METHODS

1.Polar Co-Ordinate System

2. Relative Co-Ordinate System (2d&3d)

3. Absolute Co-Ordinate System (2d&3d)

POLAR CO-ORDINATE SYSTEM :

Its can be located by definining the distance of the point from the current point. Andthe angle that the line between the two points makes with the positive x-axis.The promptsequence to draw a line from a point at 1,1 to a point at a distance of 5 units from the point(1,1),and at an angle of 30 degrees to the x-axis,is

Command: Line (enter)

From point : 1,1

To point :@5

IInd CLASS

RELATIVE CO-ORDINATE SYSTEM :

In this system the displacements (DX and DY) along X and Y axes are measured

with reference to the previous point rather than the origin. In AutoCAD this system is

designed by the symbol @ and should precede any entry. To draw a rectangle that has

lower left corner a point (1,1) the length of rectangle is 5 units and the width is 3 units .

+Y

-X 0,0 +X

-Y

Command: LINE (ENTER)

Specify first point: 1,1

Specify next point or [Undo]: @5,0

Specify next point or [Undo]: @0,3

Specify next point or [Close/Undo]: @-5,0

Specify next point or [Close/Undo]: @-3,0

ABSOLUTE CO-ORDINATE SYSTEM :

In this system the points are located with respect to the origin (0,0).For example

to draw a rectangle x=5 and y= 3 is measured five units horizontally (displacement along the

X-axis )and three units vertically (displacement along the Y-axis)from the origin.

Command: LINE (ENTER)

OPEN: Opens an existing drawing file. (CTRL+O)

SAVE AS : Saves a copy of the current drawing under a new file name. (CTRL+SHIFT+S)

CLOSE : Closes the current drawing.

EXIT : Exit the auto cad software. (ALT+F4)

LIMITS : Sets and controls the limits of the grid display in the current Model or layout tab.

SNAP : It is used to set increments for cursor movement. While moving the cursor it issometimes difficult to position a point accurately. The SNAP command allows you to set up

an invisible grid that allows the cursor to move in fixed increments from one snap point an

other. The snap points are the points where the invisible snap lines intersect. The snap

spacing is independent of the grid spacing, so the two can have equal or different values.
