I have an assembly that I was working on and once I was done, it showed that all of the features were showing fully defined. I got pulled onto another project for a few weeks and when I came back to it, and re-opened the assembly, it now shows under defined. Is there a way to show what features/components are not defined yet? I can't see where anything is wrong and if I click and try to drag any of the components to see if any mates are broken, nothing moves so it acts like it's constrained. Thanks.
If they were all fully defined earlier, but now show that they aren't, try a Ctrl+Q rebuild. That almost always works for me.
