1. CADopia Standard
CADopia Standard is an AutoCAD compatible CAD program that can be used to create or edit both 2D and 3D drawings. This application is designed for professionals (even though this is not the Professional Edition). It includes drafting features such as fly over snapping, poly line creation and complex linetype support.
CADopia Standard sells for $649, but a 30-day trial is available (with the print and save features disabled). The Professional Edition sells for $949.00.
