copying coupling doesn’t split pipe

[edenbensal]

im using geberit mapress pipe
im putting coupling at 60 cm above the floor
in the levels above i want the coupling to be at same place - 60 cm above floor
im copying the coupling and paste it to selected levels but it pasting without splitting the pipe. it’s overlapping into the pipe.
there is a solution for this?
another question
when im copying the coupling from level 1 to level 2 the reference level stays at both of them “level 1” instead of changing the coupling at level 2 to be at level 2 reference.

This is expected in all aspects. Fittings won't cut into the pipe when copying. If you want to copy stuff to other levels, you will need to paste aligned to the levels.

Hello @edenbensal,

Unfortunately, Revit will not split the Pipe automatically when a coupling (Part type Union) is placed on the pipe or copied to another or the same Pipe a bit further away.

If it is very important that the coupling is in the exact same place in the levels above I would use one of the options below:

• Copy the coupling over to the other levels and split the pipe a certain distance from the coupling. Select the end of the pipe and drag it over to the just copied coupling. The remove the coupling you just placed via the split tool.
• Copy the coupling and the Pipes at the same time and adjust the pipes to connect to the other Pipes. Split them first.
• Place a model line in the center of the coupling in Level 1 and copy that one over to the other levels and then use the split functionality and select the intersection of the Pipe and the Model line to split the Pipe and place the coupling.

if you change the Coupling from a Fitting to an Accessory you can place it as needed and it will cut the pipe.  it will no longer be a "Fitting" so it will not show up in a fitting schedule, but it will break into the pipe as a union would.

your first suggestion sounds great i’ll try it
thanks

i didn’t thought about that at all. 

im waiting for the video. 

thanks a lot 🙂

Copy/Paste of a coupling (or any fitting) doesn’t “re-cut” the host pipe — it just places geometry, so it can end up overlapping the pipe instead of splitting/connecting.

Reliable options:

1. Use Split Element (SL) at the desired elevation to force a real break and let Revit place the union based on routing preferences; or

2. Use Create Similar / Pipe Fitting to place a new coupling so Revit connects it via connectors (instead of copy/paste).

About Level: fittings typically take their level/host behavior from the pipe they’re inserted into. So for multi-level workflows, copy/paste the pipe segment + fitting (or use “Paste Aligned to Selected Levels” on the assembly), rather than pasting only the fitting.

If this is highly repetitive, automation is usually the right answer (Dynamo or an add-in). MAKHUB has a distance-based pipe cutting tool that inserts the selected union family and keeps connectivity.
