In the attached file, my part imported from Rhino3D and then transformed via Featureworks, I get 2 origins: the one from SW and a second one that can neither be selected nor modified....
As a result, when you edit a sketch, it is constrained by this second.
Do you have any idea how to delete the second one and constrain it to SW's? I have about 30 identical files..... :(
Thank you for your answer, but I can't release a SW origin. For the second one, it could work but I might as well do a "Move bodies" function but it's still quite painful to do for all my parts... But I don't see any other trick at the moment.
