Using SW2015 SP5 - wondering if any of you have seen this and found out the cause for it and a work around. I have an inserted part (just planes and sketches) that will not rebuild - no matter what I do: open the base part into memory, Cntrl-Q, Cntrl-B -   nothing can get rid of the rebuild icon next to it. It does not affect its operation - i.e. it does update when I edit and save the base feature, its just weird that the rebuild icon does not go away?
