Based on program level, divided into:
Low-end programs: Have just the basic drawing capabilities
Commonly used for general drawing works
Mid-range programs: Almost 80% of all the cad programs fall here
Offer advanced drafting techniques such as layers, 3D, basic database capabilities, advanced dimensioning and many automated drawing features
Commonly used by architecture and engineering design firms
