P-Trap coming into the model incorrectly

Hello,

 

When I go to load my p-traps into my model they come in with the incorrect orientation. I'm using the sample p-trap family so it shouldn't be an issue with the family I wouldn't think. If anyone has seen this before I'd appreciate the feedback. Pictures included below for clarificationP-TRAP1.pngP-TRAP2.png

Personally I think the P-trap family has been designed to be nested into plumbing fixture families rather than used as a stand-alone component, but that's just an opinion.

I've never had success getting it to insert correctly on its own and always end up having to disconnect it, spin it around in a section view and then reconnect it.

Hello,

 

I would suggest making the p-trap part type value Multiport and inserting it manually, using the spacebar to select the desired end to be connected.

This does not seem to work.  I cannot be the only person with this problem.  I also cannot get sewer pipe fittings to point toward the discharge.

It does work. For th OP Maybe not for you, yet. Keep trying.

 

You're not the only one that struggles with this family.

Drafting is a breeze and Revit doesn't always work the way you think it should.

Which families?

I'm not at a workstation to check, but I recall it having to do with either:

 

- Pipe drafting direction (drafting from fixture to main is consistently correct for me)

- Pipe system flow direction, which you would not currently have established in the photo as there are three connectors open

 

EDIT: Gave it a go. When you draft from the main 'up' into the fixture, the trap position winds up being on the wrong plane like in your example. If you are using plumbing fixture families or any family with pipe connectors, using the Connect Into command, clicking the connector graphic to start the Draw Pipe command, or right-clicking the connector and choosing Draw Pipe will all guarantee that the drafting direction (I need a better term for this that is more modelling-appropriate) is correct for p-trap alignment.

 

And for what it is worth, the P-trap family I'm using is the OOTB one, with Part Type set to Elbow.

When modelling wyes, you absolutely must have only one open connector in the system. If you do not, Revit has to 'guess' the direction of flow. You do not want Revit to guess the direction of flow, because it will not take existing wyes as reference points (even though a human would).


If you have an uncompleted main, like in the original picture, temporarily cap the upstream open connector. If you do, Revit will only see one open connector and 'should' point wyes in that direction. If it continues to not do so, you'll have to look for more open connectors in the system (unfinished plumbing fixture connections), closed loops (sanitary/vent interface), or bad plumbing fixture families (see "Getting Into The Flow" autodesk university presentation), as those would be the other potential sources of flow misdirection.

I've consistently encountered this problem, and the given solution has not helped. Here is what I found to solve this problem:

- start with 90 degree elbow

- change the fitting to a generic revit elbow

- change the fitting to a p-trap and it will be in the correct direction

 

Seems tedious, but I found that it is quicker than trying to fight redrawing and reconnecting.
