Trying to replace parts and sub assemblies inside a drawing and top assembly (many at once). I have managed fine with using Pack and go, but what if there is an already existing part (or parts) that I do not want to overwrite; I just want to replace the reference. Pack and go does ask if I want to overwrite or not, but if I don't overwrite the file it doesn't replace the reference in the assembly. Is this how it works for everyone or just me? Using 2014 no PDM software - Windows files only.
