I recently upgraded from WIN7/32 to WIN10/64. In the past, under Add-on, there was a Part Library. Simple and usable. Now there is only TraceParts Library. I tried copying the PartLibrary directory from the WIN7/32 computer into the to WIN10/7 Add-on directory. It's not recognized by the Add-on Manager. I can't find any reference for a new download on the 3D Systems site.
