Hi Guys,
can anyone try to operate these two objects with boolean union, diff, isect, merge?
It just calculating for minutes and minutes and nothing happens.

When I try to move one and do a boolean while not 'in sync', it seems working.

CPU is at 14%.
I have i7 7700
16G RAM and MoI is on SSD

This should be quite simple operation looking at the shapes on forum that others did.

Thanks,
Juraj
