This is new as of this morning. I've got a busy pressure pipe model, for irrigation piping, I can create a profile view, and place pipes without problems, But as soon as I try to Break a pressure pipe in profile view, the application crashes with a fatal error on selecting the pressure pipe to break. Audit show no problems.
I tried Dreffing and promoting the pressure network into an empty drawing (and added the surfaces, alignments and profiles to create the profile views, but am still getting the instant crash.
