LiteCAD

   LiteCAD is a 2D CAD program. The editor can be used as a multi-purpose drafting application. The main component of the package - LiteCAD DLL library is intended for software developers who build own specialized drawing applications, CAD / CAM / GIS type. This component provides vector graphics possiblilities and has a simple API for using it with the popular languages such as Visual C++, C#, Visual Basic, VB.NET, Delphi. LiteCAD OCX module provides ActiveX interface for the DLL.
