For a new user of Revit MEP, it might be useful to know how to join two slanted pipe runs that are not at the same elevation. This might happen where one part of the system is modelled first, before it needs to be joined to a run that cannot have its elevation adjusted. The elevation of the branch must then be adjusted.

As the pipes are typically drawn at 45 degrees to each other (the usual arrangement), I have found that an array of sections is useful to view the respective items with. These sections are moved as a unit when working on the pipe system.

The section shows the problem clearly with the incoming pipe at a higher elevation.

Draw a pipe from the main runner to run parallel to the incoming pipe. Make sure to inherit the elevation of the pipe that the branch is being drawn from, that the slope is correctly oriented (up, in this case), that the value of the slope is correct and that the diameter is the right size.

Align the centre lines of the pipes in plan view. Note that the two pipes need to be joined and keep an eye on the elevation of the pipe termination when the branch is eventually moved down.

Open the section and align the centre lines of the pipe again. Drag and drop the one pipe on the other pipe connector by using the “sx” point snap.

The pipe termination is now still at the elevation it started on even though its run was dropped in elevation.

Here the result is shown in 3D.
