What tricks are there(if any) for keeping file size of parts manageable. I have had a couple of part files grow to over 60 Mb. Gets a bit cumbersome in assemblies. These parts have lots of surfaces, (some imported) and a fair bit of spline data. I know the usual things like not save edrawing data etc., Is there a way to "flush" a part file (without loosing the history) and keep the part size manageable. thanks Matthew
