Revit MEP Pipe connection issue

sfulpJKYDA — Tue, 11 Mar 2025 12:35:00 GMT

Is there any way to reconnect two straight, inline pieces of pipe seamlessly with each other without either deleting one piece and dragging the other to another connecting pipe or creating a coupling? For example: If I split a piece of pipe in half, I either have to delete one piece and reattach the other to either a fitting or another piece of pipe, and it still creates a coupling. I want to be able to reattach two pieces of pipe together without creating a coupling. Is there a button or hotkey to do that?

Use Trim Tool (TR) to connect the two pipe, than becomes one

Delete the coupling.

Grab the end of one pipe and drag it onto the end of the other one.

They will combine to one pipe.

I tried this and it did work, but it disconnected the hanger that was in the section of pipe. For some reason it also added an extra coupling on the end, so I still had to go back and delete the extra coupling and pull the pipe to the 90.

Is this fabrication piping? If so, I use optimize lengths to remove couplings, and I think the hanger will still be attached.

Yes it is fabrication piping, and I just tried that and it worked! Thank you!

"Yes it is fabrication piping"

It would help us to help you if you make this clear in any future posts - fabrication parts act differently from "Revit pipe".

The assumption is usually that you are talking about Revit system pipes/ducts and families unless you say that it is fabrication parts.

It sounds like you want two inline pipes attached to each other without anything between them. That condition is impossible in Revit and IRL.

Am I misunderstanding?

No I know that is impossible, but I think it is easier to explain what I am trying to say using an example:

Say I accidentally split a singular piece of pipe (that is between two 90s) in half and do not realize it. I go on to add few Ts and a few welds using MEP Fabrication Parts on the same line of pipe that I accidentally split earlier. I realize and do not want to go back and undo all of the work I have done up to this point by either hitting ctrl+z until it's all undone or deleting one section of the pipe that already had Ts and welds attached to it and dragging the remaining piece of pipe to the other end to connect with the 90 because that means I will have to reattach all of the welds. Is there not a function where I could simply reconnect the two pieces of pipe that I split into two without disconnecting and breaking all of the welds that were associated with one of the pieces of pipe?

No. One of them needs to be deleted.

Click on one pipe or fitting then select Route and Fill. It should show you the options to reconnect, if possible with available fittings, and then Optimize lengths to get rid of unnecessary couplings. Multi-Point routing should work too.
