Heavy consideration was given to whether this family should be a face based family, a wall based family or a level based family. A wall-based would seem like the obvious choice given down pipes go on walls. But that would make it very inconvenient when you decide you to have concealed downpipes. A face-based family would cause similar headaches, but not only that, wall hosted elements have a tendency to be deleted quite easily when changes to its hosting element are made. Ultimately a dual level based family would allow the downpipe to automatically flex with changes in level height, and offered much greater control.
Some may ask why this family isn't categorised under Plumbing Fixtures, it just makes sense. But unfortunately, Plumbing Fixtures are one of Revit's many categories that can't be cut in plan. We could have used detail lines to represent the down pipe being cut, but this became difficult when trying to represent the kick if it was cut instead. The Generic Models category was the answer, that combined with some selective object style naming, meant flexibility with its general visibility and graphic appearance.
The best way to place this family is in plan. Select its top and bottom level constraint, allow for any offsets you may like, and from there head to your 3D view and start customising.
To account for the fact this family isn't wall based a lockable reference plane in line with the walls edge allows you to lock the down pipe to the wall.
- Only one Rainwater Head design has been included so far. But being a nested family, this is very simple to update.
