Creation of geometries by Coordinate system methods using AutoCad
Using imperial templates and decimal units to create geometries from co-ordinate systems.
After opening Auto-cad, type startup. Type 1 for creating a new template file we can then go to file on top left in order to open a new file. After all initial settings are completed, we can now start the project.
