I have a classic scenario of "make an enclosure master file and split it out". So, for most of my parts I can just use the shell tool to get my wall thickness but for this part it works but doesn't work. If you are willing....Shell the part and include the large flat face. It shells but there is a caution on the shell feature. What a tease! I will now have to make an elaborate series of offset surfaces, trimming, knitting, etc....
Can anyone shed light on this? If the part seemingly shells why it has a caution and therefore unstable geometry?
See the attached part.
