new Frame Generator weirdness?

[jnewon]

Hey

This seems like new FG issue. Or at least I haven't seen this before. I have a frame member that has trims on both ends. I go to edit the frame member to offset it a distance like a 2 in. The member errors on one of the trims and total wigs out. The member flips direction. I can't even change the offset back. The trim is broken. It' has happened a few times while trying to build this platform. I have to delete and redo both trims.  I do work with the frame generator quit a bit but I haven't seen this before. I feel that inventor is flipping a plane or planes used for the trims. I say this because I delete the offending trim and the member is gone. Meaning the part was trimmed out totally with the remaining trim. I delete the remaining trim  and the member is back.

Hi! This could be related to the end treatment. If possible, please share the files here. I would like to understand the behavior better. Are you using iMates? Could the iMate source geometry be removed by the end treatments?

Many thanks!
