Definition of AutoCAD;

Automatic Computer -Aid Drafting

AutoCADis a CADsoftware applicationfor 2Dand 3Ddesignanddrafting.

Developed and sold byAutodesk, Inc. First released in December 1982,AutoCADwas one of the first CAD

programs to run on personal computers, notably the IBM PC. At that time,most otherCAD programs ran on mainframecomputersor mini-computersthat were connected to a graphics computer terminalfor eachuser.

AutoCAD derived from a program called Interact, which was written in aproprietary language (SPL) and ran on the Marinchip Systems 9900

computer Marinchip was owned by Autodesk co-founders John Walkersand

Why AutoCAD?; 1. We Always Draw in Full Scale

2. Show Different Area of One Model

3. Less Styles to Manage

4. Easy to Control Drawing Scale

5. Different Drawing Orientation

6. Different Drawing Representation with Layer Properties per-Viewport

7. Get the Advantages of Annotation Scaling

8. Control Printing Preferences Easily

9. Sheet Set Manager Advantages

10. Batch Plot

Input System Everything drawn on AutoCAD are drawn at accurate scale. The drawings are placed on the sheet by

co-ordinate system. In 2D, it is two axis -X,Y co-ordinate system and in 3D it is three axis- X,Y,Z co-ordinate system. You can see it while moving the cursor (which is actually called Cross HairinAutoCAD) in the workspace, at the lower left corner the co-ordinates are shown simultaneously.

The default co-ordinate system is called WCS (World Co-ordinate System). Everything you draw, aredrawn inWCS. Sometimes designers need to change the default co-ordinate system for drawingpurpose. That is called UCS(User Co-ordinate System).

Those were all linear inputs. But sometimes you have to draw angular lines. In that case you have tomention the angle. In AutoCAD angle is measured counter clockwise. The 0 degree starts from 3oclock, then increases counter clockwise.

For example, you have a line and need to draw another line at the left point at 450angle (Fig. 1). Nowfrom the left point, upside the line, if you start measuring angle , it goes counter clockwise. So simplygive the angle value 450. But if you have to draw the line from the right corner, the measurement goesclockwise. So you have to imagine it counter clockwise, then value should be 900+450= 1350.

(11A) Layout(proper

scaling & printing)

STEPS ARE;

1 From modeldrawing area, CLICKthe Layout1 or Layout2.

2 You can change the name of layout and edit by RIGHT-CLICKINGthe Layout.

3 Press control P or press the printer logo in menu bar, the plot window will appear, then adjust the

paper size and units as shown above for us to have the proper way of scaling.

(11C) Layout(proper

scaling & printing)

At the figure above, this is how to insert a viewport in our Layout printable are., it is found at view rolldown toolbar. See figure above.

6 SCALING after you inserted a view port, you can now scaleby, double-clicking inside the rectangleview port, then type Z then SCALE. For example, you want to scale it to 1:100, you should type,

1000/100XP.

(11D) Layout(proper

scaling & printing)

7 If we are done in our Layout, we can now print and see our output preview by clicking the window,then select the end to end of our border, and click the preview to check the output.

8 If its OK, you can now print by pressing the OK button, or right clicking-then plot.
