Hi, Michael.

I've tried to shell the lower face of the item in the attached file at various widths from around 0.1mm to about 2mm wall thickness, but MoI seems to be struggling a little and I can't really see where the problem lies. There is also an issue with insetting the same face (again around 2mm), in that MoI creates a separate inset solid. Can you point me in the right direction for sorting this out please, or is it just a current limitation of the kernel?


Thanks, Martin.
