I really appreciate your comments and ideas. But I like to stay with visual basic 
Maybe we can solve the issues that I have by simplyfying the context.
Given:
LDrawObject with radius of bounding box = radiusbox
Result:
Code in pure openGL, where the LDrawObject is drawn with a function called DrawLDrawObject()
DrawLDrawObject() only uses the colors and vertices just from the files.
So there needs to be code for the world and for the modelview that i am looking for.
Anybody out there who can help and post his (working) code here?
