  EWDraw is a powerful vector graphics ActiveX for 3D and 2D visualisation and animation. You can use it for CAD,CAM,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 Visual Basic, Delphi, C++ Builder , Visual C++, .NET and INTERNET
