I have this assembly that was going to get well over 200 parts and decided to brake it down to smaller sub-assemblies. To do this I went into SolidWorks Explorer to rename sub-assemblies and parts. When I did this on my first assembly it gave an error and said "rename failed". So I tried several times with different new name still same result. So I made sure SolidWorks was completely shut down and went back to do it again, same result...So I restarted my machine and only opened SW Explorer to find that the assembly I was renaming was there but it said file not found and was red. I opened SW to find the assembly was not there in the folder I saved it in....I re-checked out my assembly from PDM and tried again, still same problem. Now I am here feeling a little sick and dizzy from all the go around desperately looking for a solution......PLEASE HELP!!! SolidworksSolidworks Explorer
