Hi Bob, well the reason why the web site discusses mechanical models is because CAD programs in general are better suited for creating man made type objects rather than organic shapes such as creatures or character models.

The basic modeling process that is used to create objects in MoI is by drawing 2D profiles and then using those 2D profiles to generate solids and use other 2D profiles for boolean cutting operations. That's very different than the "sculpting vertices in 3D space" type approach that's used by polygon mesh based modeling programs.

So those things on my web site are basically about trying to emphasize that kind of general difference between what CAD programs are good at and what polygon mesh modeling programs are good at.

It doesn't necessarily mean "large scale highly detailed industrial part design with lots of components" specifically, sorry there was some confusion over that.

In time MoI will have those features added but the primary focus of it currently is on making it really quick and easy to create basic mechanical objects, not really focused on detailed assemblies as of yet. If you're looking for an industrial production mechanical part designer, you probably want to look at the more heavyweight programs such as SolidWorks, SolidEdge, Creo, etc..., all of which of course have a price tag about 20 times or so as much as MoI. But they have a big focus on the types of things you are describing, also at the same time not having anything like the quick and easy drawing feel that MoI has.
