Hi

I have done something to my MoI , that now I can only extrude in the Z direction.

In Top view I draw a Straight Line in either X or Y , it will only extrude in Z. I restarted MoI same thing, I reset Cplane, still no change.

I have no idea what I have turned on or off, MoI V3 Nov Beta

Cheers, Steve
