This topic is cross-posted from the surfacing forum.
I have an imported part that I am doing a core/cavity split for. I kind of use the mold tools, but not completely. I have all of my knit surfaces for core, cavity and parting surfces in the part file but for a few reasons that are not relevant to my problem I choose to do my split in the context of an assembly.
I create my core and cavity blocks in this new assembly-then bring in the molded part and position it. I then edit the core and copy the core surface and the parting surface; knit them together and do my surface cut. No problems.
Then when I try to do a similar thing for the cavity, I get an error message when I try to offset the cavity surface by a distance of zero: resultant body is a self-intersecting surface. News to me. I go back to the part and look it over and find no problems. Then I try to offset that same surface in the part file-just for grins. No problem-no error message-everything looks fine.
I go back to the assembly and edit the cavity part and try to offset either one of these surfaces with no success. Anybody have any ideas on what is going on? A body check shows no problems, by the way.

In order to understand this of course it would help to have the file posted or an example. If it is propietary, you can send it to mbiasotti@solidworks.com and I'll have a look at it for you. If it's too big email me and I can provide for you an FTP site.
