Pinning sloped pipe to keep it from moving around

[Tye Austin]

I have a new guy working for me and I realized how paranoid I am about a new-to-revit user doing any moves on sloped gravity systems.  they act so odd.  if pipes are graded and there are 45 offsets anywhere, if you bump a branch line on the 3rd floor it can change the location and elevation of a main in your underground...  I was just thinking... Maybe I could just pin all the UG once I have it dialed.  Never tried that.  anyone have any creative solutions to keeping things from moving around on gravity systems or have you tried pinning an entire UG or floor of piping?

Yes, we did this a lot when our guys were never to Revit. I don't recall it causing any performance issues.

Another thing you can do is create an editable workset for yourself and place the pipe on there that you don't want moved. You will just need to make sure not to relinquish that workset when you sync. Though, depending on your workflow and how you use worksets for other processes you may not want to do this.

This will ensure no one else besides yourself will be able to edit/move the pipe without a permissions error popping up.

We've pinned whole floors before. Stopped doing it quickly though because then we'd have to unpin to do changes, so now we just pin critical areas. The main thing we do to prevent things moving from floor to floor is we don't connect sloped systems in between floors. We stub our pipe through the floor and then when we start drawing on the floor above, we place a fresh band, coupling or fitting to the side and move it on top of the protruding pipe without connecting it. By doing that if something does move, it only affects the one floor and it makes it nice to use tab to select a system just for that floor. With our workflow, there really isn't any downside to doing this.
