What is MV's suggestion for sorting this issue out once and for all. I do not want to increase the distance between parts as this will make things very very inefficient but i'm pulling my hair out having to fix things all the time. 

I'm getting to the point where i'm going to look at exporting all pieces from MV and importing into Bsolid directly for it to do its far superior nesting and toolpathing, but am i jumping the gun?

Our biggest nesting tool is 12mm.
