the join feature does not alter the CS. The relation between the part CS and the assembly CS will be determined by the mates used to define the location of the part in the assembly when the join feature was made.
from your table i would guess that this was a virtual part with an "in place" mate.
Thanks for pointing me in the right direction. I didn't properly constrain the new part to the assembly coordinate system prior to inserting the join feature. Had to:
- edit the part in context
- suppress all features
- go back to assembly
- correct the assembly constraints
- edit the part in context again
- unsuppress the features
Glad it worked. and you shouldn't need the suppress and un-suppress steps - just correcting the assembly constraints and a rebuild should do the trick.
