I have a large multi-body part that I now need to break into individual parts. I need to do this because I don't trust the multi-body part and because it is a huge file (14 MB) with over 500 features and 14 unique parts. When I try to separate the files, I lose all features and it doesn't translate sketches, which I use for positioning other parts (not within the multi-body). I tried saving all the parts as flat patterns, then creating a new part from the flat patterns and adding bends, but for some reason the geometry does not match the original parts (even using 8 decimal places on the angles).
What is the best way to separate a multi-body part into its components, while removing references to the original file, and making it editable for the future?
