As my recolector tells me....
We used to be able to open a preview of a part or assembly that was dumb. (no features only surfaces)
I have asked my coworkers and it appears the function went away last year????
Does anyone know?
The reason is that I wanted to look at an old model and I didn't want to deal with all the possible failed features etc that comes with ....
Well, we have all experienced it.
In the open dialog there is a drop down menu labeled "Mode". For opening a part or a drawing you can set it to Quick View.
For opening an assembly you can set it to Large Design Review.
