a powerful vector graphics ActiveX for 3D and 2D visualisation and animation.
BSEditor: EWDraw 3D ActiveX is a vector graphics ActiveX for 3D and 2D visualization and animation. You can use it for CAD, CAM, and GIS. The EWDraw 3D ActiveX is based on open cascade geometric kernel and openGL. The library is realized as a run-time Windows 32 bit 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. Version 7.0 adds Undo/Redo function, Edge4Surface for Create surface by 4 edge, Edge3Surface for create surface by 3 edge, Split3DSolid for split a 3D solid by a plane, and various bug fixes.

Improve OpenEwd and SaveEwd speed.
.Improve Boolean opration
.Improve Is3DSolidIntersect.
.Add IntersectShapeWire function for support get intersect points Between a 3D solid and a wire.
.Add new function support compound (unite) entitys between shape and wire
