TwinCAD is an easy-to-use design and drafting program for preparing precision CAD drawings.  With its powerful CAD engine, TwinCAD offers comprehensive 2D CAD functions that are comparable and compatible with AutoCADtm, while in a more thoughtful and productive way.   You may use TwinCAD as a standalone CAD system which does virtually all the design and drafting work for you, or simply take it as an add-on feature provider for AutoCADtm, as its DWG compatibility would allow you to work around the two systems freely. twcadpro.jpg (11125 bytes)
