I've run into a couple issues that I would like to see if others can repeat or not.
1) When I enter properties under the weldment feature in a template drawing these properties do not show up in the parts created from that template. I thought this was just a weldment issue but apparently this works for some people. How to automatically run macro on model open (without add-in) Some of the later posts.
2) When an assembly has been checked in and released in the PDM. When you then check that part out for an EC, when you modify that part the part disappears from the assembly. I fairly regularly have to close the assembly and reopen it in order for the part to show up.
I will send these off to my VAR but it's always nice to now that other people are having the issue and helps to narrow down where to look for the issue.
