AutoCAD is 2D and 3D modeling software developed by Autodesk for computer-aided design. It allows users to draw and edit designs by providing commands for basic shapes, modifying objects, and viewing objects from different angles. The software uses a coordinate system to locate objects in a drawing by specifying x and y coordinates from an origin point.

- 7. • To draw a drawing first we need to check units i.,e. for mechanical engineering we choose decimal type in that mm scale. • It will found in menu bar ,format, units • Later we can give co-ordinates and start drawing How to draw a drawing
- 8. HOW CO-ORDINATE SYSTEM WORKS • There is a co-ordinate system used in AutoCAD. • Every drawing shows its co-ordinate. • To give co-ordinate we need to have an center point • so we need to start with an origin point (0,0). • In following figure the line shows its co-ordinate that is ( 100,0 ) and (0,100).
