Your source for the KOP parts will make a difference with what you can do with the part files. If you got them from Andymark the are standard part files. If you got them from Autodesk most are part files that a relatively new feature called base solids. Basically this limits editing of standard parts. Example: Frame rails can only have their length change by moving a face while in the solid editor. I have not played with it much but this is what I found so far. I can see this being used in industry but is a little cumbersome for our team at this point. Hope this helps.
