I often compare old and new part files to see thedifferencesbetween them in order to make changes to tooling butoften times(more than not) volume comparison fails. This can happenon fairlysimple parts as well as complicated parts. I haveconfirmed thatthe feature works with a simple cube and then a cubewith a holethru it and it sees the difference there but on just alittle bitmore difficult part it fails consistantly. Anyone elseseethis?
