I have noticed similar issues in the past and have resorted to partially recreating frames.
I am working on one frame where I have rebuilt two parts multiple times and they still revert to being rotated slightly after performing a rebuild. I can continually hit the rebuild button and watch them rotate back and forth. Is there a known fix for some of these oddities with FG?
Notice the two tubes in the attached pic. I do not understand why they continue to rotate out of alignment after they are placed correctly. (They even look fine when placed.)

There is an open, confirmed issue with development about some frames rotating 90 degrees after a rebuild – 1351440 – and it seems to be due to an offset, but the only way to tell if this falls into this issue is to have the data set. Would it be possible for you to upload this or a simplified version that exhibits this behavior? Thank you.
Tubes generated with frame generator twist slightly. They look okay until dimensioned. When two different tubes with edges that should be co-planer are dimensioned where a distance should be displayed an angle dimension is displayed.
