VeCAD (including dimensions & DXF/DWG import/export)

"VeCAD is a vector graphics library. It can be used as a
multi-purpose drafting tool or as a base for your own
specialized drawing applications (CAD/GIS).

The VeCAD package also includes a powerful CAD editor in
executable form, based entirely on the VeCAD engine. Use this
application to visualize your own project's possibilities!"
