I just did a quick little test for schematic views.
I created a hanging position from 4 pieces of truss.And 1 lighting instrument. I choose to use geometry for the hanging position.
Creating the schematic view takes multiple minutes of beachball to complete.
Once the schematic view is there only 1 out of 4 pieces of truss is displayed in the schematic view. (the one that has the instrument attached.)
Moving a schematic view takes another couple of
Also had another one with units displaying a weird second model if the label legend had a different model to the unit used in the schematic view, will try get a picture tomorrow
