The other day I was changing the assembly template because I updated the custom properties tab. Today, I have discovered that any time I make a mate with this new template, SW crashes. Also, the planes in the feature tree have disappeared. I am sure that all I changed in the assembly template was the custom properties tab, and the old template is still working correctly, so I have no idea how this happened.
Open an existing assembly file
Change custom properties reference
Save as .asmdot
Create drawing and make sure everything is working correctly
I DID NOT actually make any mates that day with the new format
This is happening on all 3 of our computers, 2012 SP4.
Anyone else have this problem, or see a mistake in my method?
