I have a couple of questions here. Does OpenCascade provide any tools for interactive drawing and editting of shapes? If so, how is this done? The other question is; how can I change the properties of a TopoDS_Shape? Example: I create a solid sphere, using BRep_MakeSphere. After it has been created, how can I change the radius of the sphere, for example? I mean, how can I reach the underlying geometry?
Thanks in advance for the help.
