I am trying to add a view of a part that is a FULL, TOTAL Xsec but the part being in the DEFAULT orientation. However, in the DEFAULT (Isometric View) view, none of the DATUM can be PARALLEL to the screen.
You can only make a true cross-sectional view when the cutting plane is parallel to the screen.
Alternately, you can make an assembly cut of the model and use a family table and suppress the cut in an instance. You can also use Simplified Reps or View Represent. Remember, though, how this will affect your Master Rep. Your master rep will have the cut.
