I can't seem to find anyone asking this...I'm probably just stupid, but I have an assembly step file that I have opened in SW, and used "derive component part" to save out one part. I want to use feature recognition on this part, but the command is greyed out. What do I need to do to import all the features of this part into the tree? do I need to redraw the part from scratch using the step file as reference, or is there a way to import the features?
