I want to change the name for a parts file but when I do the images appear blank in the drawing file. Is there a way around this?
Yes there is Matt ... I would ask what your end goal is here though because there are multiple ways to get what you want. If the link below doesn't answer everything for you please post what you want to do specifically and we can get you there.
A great link that would be of assistance ...
My Drawing or Assembly can't find dependent files.
See the bottom portion of My Drawing or Assembly can't find dependent files.; the paragraph beginning with "In the future..."
Change part numbers using SW Explorer
Also you should have gotten a warning about missing part and it even gives you a chance to go find the part. So I would also look under Settings/ Message/errors/warnings Big box to the right "dismissed Messages".
the easy way to do this is to open the drawing and any assembly the parts contain. then do a save as on the parts you want to change the name of. This will update the assembly and the drawing file links.
