I was helping a co-worker earlier today with an issue that I can't determine a cause for. We have SolidWorks 2010 and use EPDM for managing our part and drawing files. He had copy/pasted a part file that had been created outside of EPDM. He attempted to do a copy tree on the part file and the design tree in the resulting part had only the first two actions. The remaining operations in the original design tree were completely missing from the 'copy tree'-d version. Any thoughts on why this would happen? Thanks!
