EWDraw can be used for viewing CAD,GIS and others. The EWDraw is based on Open CASCADE geometric kernel v 5.2 and openGL.

The library is realized as a run-time Windows 32 bit OCX (ActiveX control). Either can be used with applications written in the popular Visual IDE languages such as Delphi, Visual Basic, C++ Builder , Visual C, .NET and INTERNET

Limitations:

· Some functions disabled
· Nag screen
