Absolutely love MoI, however; I am experiencing a couple of problems on a current project...

Problem 1:
I have noticed that when editing certain spline objects (closed circles), the centre point for them disappears making it very difficult to align things to? Is this normal?

Problem (question) 2:
Is there any way of cloning a single object to multiple points in a scene? (example, cloning a single screw head to multiple, defined points on a surface).

I know that I'm asking probably beyond the softwares capability, but if anyone can help or offer a possible solution I would be most grateful.

Many thanks!
