We badly need to be able to turn off plumbing fixture but leave the tags visible, and we badly need masking ability so that pipes in front of other pipes show a slight "break" in the pipe behind the foreground pipe. Another nice option would be to turn off the fittings (elbows, tees, etc) and just see straight line diagrams. We really don't have to have the added detail For sewer and water review by the state health departments.
