I just upgraded from SW2015 to SW2017 and I am finding all of a sudden that I cannot reorder my assembly tree by dragging features and components. In all my previous models, I used the following tree order:
Reference Planes and Axes
Parts and Subassemblies
Now, SW2017 is putting my sketches and reference planes below the parts and mates, and I cannot move them directly beneath the primary planes. Is this intentional or is there a glitch in the installation?
