Hi Nick, so I guess the thing is that mechanical lines 'n arcs type stuff is already handled so well by MCAD programs (SolidWorks, SolidEdge, Alibre, etc...) that it just didn't make sense to me to make MoI to be in exactly the same mold as those so to speak...

MoI is trying to be more of a hybrid between CAD and 2D illustration sorta.
