I needed to change 4 part numbers in my assembly. I left clicked on the file and selected SOLIDWORKS then RENAME. It does not show where the detail is used which is strange cause it is used in several assemblies.
Then when I open the drawing for the assembly it still shows the old number, if I left click on the BOM entry it gives the option to open the detail part and it does show the correct part/file number (my new number)
What is going on here?
