HI DesertRaven, it would be a really cool thing to have in MoI!

But unfortunately it's far from simple to implement such things - even implemented at a basic level there is a whole lot of work involved, much more than what you might think... So I'm sorry but it's not likely to become a built in part of MoI anytime soon unless you find some way to make more than 24 hours to be included in a single day's worth of work of course! ;)

Some more elaborate CAD programs do have those kinds of things in them, but MoI is much more focused on just modeling and drawing.
