Another question: Can the Parasolids engine produce reusable, parametric, 3D objects by itself?
How would a GDL-based wall and the Tool used to create it differ from the VW Parasolids-based Wall tool.
My admittedly naive view is that PS is a powerful modeling platform, but that the intelligence behind a M-CAD modeling platform using it as an engine relies on other programming do the lifting. Is Parasolids a shape engine? Or something more as well?
