While using the Parallel Pipes command in Revit on a L-shaped pipe network, I’m encountering unexpected behavior when setting the number of horizontal pipes such that they extend beyond the last pipe segment.
Use Case:
The base pipe network is L-shaped (two horizontal runs connected by a diagonal or vertical segment).
Using the Parallel Pipes tool to create multiple horizontal pipes.
When the number of parallel pipes specified exceeds the horizontal run length of the last pipe segment, Revit generates unexpected extensions or underflowing pipes that go beyond the intended layout.
Issue:
Pipes extend beyond the last segment, instead of stopping cleanly at the end of the pipe network.
This causes underlapping geometry, visual clutter, or connection issues in the model.
Expected Behavior:
Parallel pipes should automatically stop at the end of the last valid pipe in the base network.
Revit should prevent generation of geometry beyond the physical extents of the input pipe path or provide a warning.
Questions:
Is there a way to constrain the parallel pipes within the bounds of the original network?
Any known workarounds or tips to handle L-shaped configurations more reliably with the Parallel Pipes tool?
Is this a known issue with the tool or a limitation in its current behavior?
