Sloped Piping

[ArchWestCY]

Can anyone recommend a definitive tutorial on how to best create sloped piping? Specifically for Sanitary Sewer and Waste lines.

Is this feature ready for use, or is it more headache than it's worth?

Thanks for your comments

There is nothing definitive, sorry. But the way I draft sloped piping is to pick the furthest fixture and route to the POC, or from the POC to the furthest fixture. Routing the piping flat then using the "Slope" tool has not produced good results for me. After you get the general main run and are pretty comfortable with the depths, start creating branches. Some tips are below:

1. When creating branches, always route from the main to the fixture. Connect to the main and use the spacebar to get the correct offset.

2. Use sections. Change pipe depths be moving them in a section. Connect to fixtures using sections. Make vertical take-offs using sections. You can copy and move sections from one area to another so you don't have to create 1,000 for each project. One north/south and one east/west will do for most projects.

3. Generic fittings are easier to do your general routing with, then you can replace them later with the correct fitting types. I don't do this personally, but know a few who do with great speed and success.

4. Avoid flat double sided tees. If a double tee is laying flat in the ditch and it has two pipes sloping up away from the main, revit won't let them connect. I've never gotten this to work.

5. Always check "Allow Slope Adjustments" in families. It doesn't seem to matter if there isn't a sloped pipe attached to the connector. If there is sloped piping in the pipe run, not checking this has caused me issues.

We avoid it unless it is absolutely required because of the extra time it takes to get it to work/ look right.

Many many headaches.

Thanks for both of your comments. I have not yet tried going from the main to the fixture, yet. It just seemed like the intended workflow is from the fixture to the main, but your suggestion make a lot of sense. I will follow up on the rest.

After the Architect changes the toilet rooms 60+ times or adds another fixture further from the IE your going to wish you never had sloped the pipe.

It is easy to do, just a pain to modify.

By the way, I use Connect into.

It's always a problem with sloping pipes especially with tees. Thanks for some good tips. I am not very clear about the last point. I learned creating families few days back & still practicing.

I also found routing from the main to the fixture is the best way when using sloped piping. As thekaosengine stated, there's no set way in Revit to do this. I pick the fixture farthest from the building utility entrance as my starting point. The main is always drawn first, followed by branches. When going from the main to the fixtures/branches, it's a good idea to use your spacebar to get the same level of the main when you start drawing in the piping. (Hoping that makes sense.)
