Manholes, tanks, etc. with defined wall thicknesses

[Mark0514]

New to Revit but been in the water and wastewater industry for 30 years and 2D CAD for half of that. We do many pump stations and my initial thought with Revit was to create two families (one round and one square or rectangle) where I could just enter parameters such as bottom slab diameter (or dimension)/thickness, inside dimension, outside dimension, wall height, and top slab diameter (or dimension) and thickness.

I can find enough info to do this with extrusions, but because what I'm wanting are in essence walls, I'm wondering if my thinking is off and I should just build each structure as needed using the tools that already exist in Revit.

Secondly - because it seems there are no families etc. for AWWA pipe, fittings, and valves (that I can find) it seems that my workflow will have to integrate some hybrid of Revit and plant 3-D (also new to me).

Any thoughts and/or suggestions on the above would be greatly appreciated.

2018 has AWWA content

Thank you for your response. The AWWA content I would use most is C110 flanged, not mechanical joint. I don't see any flanged fittings in that directory.

You absolutely can create families that will do this for you.
Simply use extrusions to create the slab element, and add parameters to control the length/width/thickness of the slab element.
Create additional extrusion/s for the vertical elements.

Where you will run into problems is trying to connect your pipes into these, as the pipe fitting will want to start its life either horizontal or vertical and then change direction to match your slopes.

You can get around this by creating a small extrusion on which you will manage your pipe entry/exit placement and this you will need to set some angle constraints on so that your pipes can actually connect directly without having to make a small horizontal deviation to do so. The problem there lies with the connectors, so revit needs minimum distances to place connectors, reducers, and elbows so this can get really messy without having a connector that can have a variable angle on it.

I suggest you create your manhole extrusion which will be quite simple, and then place another extrusion on which to place your connector. This extrusion needs to be able to adapt the angle to suit the entry angle of the pipe (or exit) that will attach to your manhole.

Good advice! I learned a few things as well.
