EW Draw 3D Active X Description:

EWDraw3D ActiveX is a powerful vector graphics ActiveX for 3D and 2D visualisation and animation. You can use it for CAD,CAM,GIS and others. The EWDraw3D ActiveX is based on Open CASCADE geometric kernel 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
