I am tidying up some P&ID drawings from colleagues and have discovered that some some of the SLINES are the wrong type. On most I have been able to right click and choose SUBSTITUTE from the menu that appears, and they change easily.
The remaining lines don't have the SUBSTITUTE option in the right click menu. I had thought that perhaps these had detached themselves from the database, however an AUDIT of the drawing doesn't fix it, and the lines still have all their tag properties intact.
Has anyone come across this before, and if so, how do I fix it so that I can substitute? I'd prefer not to have to redraw all of these!
Additional to above - all SLINEs in our drawings that are connected to off page connectors have the no substitute issue, though some others do as well.
