Creation of geometries by Coordinate system methods using AutoCad
AIM: To create geometries P1 – P2 using all the Co-ordinate system and remaing by any of the following methods.
- Absolute co-ordinate system
- Relative rectangular co-ordinate system
- Relative polar co-ordinate system
INTRODUCTION
AutoCAD uses a standard XY Cartesian coordinate notation with a horizontal x-axis and a vertical y-axis. AutoCAD shows the positive X and Y range of coordinates with the 0,0 coordinate (origin), placed in the lower-left corner of the drawing area. The origin is an important coordinate location because you can use it as a reference for multiple drawings.
- Absolute coordinates are based on the WCS origin (0,0)
- Relative rectangular co-ordinates are based on co-ordinates of last point entered
- Relative polar co-ordinate system is based on length at which angle
PROCEDURE:
Open the AUTOCAD application
Create new drawing using the Imperial template and the Decimal Units
