Just a heads up!
Not expecting a solution.
Been drawing all day and having this problem with different drawing files, whether I close and reopen, etc...
I heard of someone having a similar problem a few days ago.
If you look at the isometric views, you'll notice the shaded one has the doors missing.
Just imagine!
If I select the shaded with edges view and change it to nonshaded then the problem disappears and it looks like it should.
I can flip back and forth and the error keeps happening when I switch to shaded.
Now go figure.
I switch to nonshaded, hit save, then switch to shaded, and now the doors appear.
Yeah!!!
But, and here's the kicker, if I hit save again, the doors magically disappear before my eyes, and the same problem all over again
Boo!!!
So anyway,
This is the second file I created today with different assemblies and the same problem.
Shrug!!!
