Yeah, the worst or most insulting of these prices being C3D, as most if not all of MAP within C3D doesn't work with C3D objects, but one still must pay full price to have MAP in there even if it doesn't fully function. I could see it costing more IF it all functioned together properly.
The bad news is any discussion of these prices is NOT permitted at the Autodesk newsgroups, NOR the Solid Vapour controlled user group formerly known as AUGI. So the company and their proxy have effectively limited the platform of debate about business model and how it impacts the end users.
