Here's a new one to me... I modified some parts in Assy. I used ISOLATE to hide all the other parts then do a Save-As to save the just modified parts as X_T files. Since it is an assy SW ask if I want to resolve the hidden parts... I say no... but it saves the whole assy anyway. Including all the hidden files.

Of course if I manually hide all the parts it only saves the visible parts.

All these inconsistencies drive me crazy. I had to Saveas the first time. Notice the file was huge and import it to see why... Then I Saveas a second time to insure I didn't make a mistake. And re-import it... Then I savedas a 3rd time and import it to insure correctness.

So odd, I'd think Isolate would just Hide the parts and Saveas wouldn't care how they were hid.
