Hello
It’s hard to reproduce the error that easily. But I think that HSM has troubles with that very large volume body.
What you could try out is going from HSMWorks 2012 R2.28345 to the HSMWorks2011-R4.26959-x64 version (last version of the 2011)
I am still working with that version as the version 2012 has still loads of “ children's diseases”...
Or you could to process the external surfaces of the pocket with 2D contours and only the islands with Z constant.
Maybe that helps you out.
Regards Speedy!
