Here are the profile view bands in Storm and Sanitary, bands include Max Q and Max V values.
How do I transfer these values to pipes in a Civil 3D pipe network?
storm and sanitary flow and velocity values to civil 3d
HI @kevin.bza,
Welcome to the forum and thanks for posting. Below you will find a help document detailing how this can be done and I'm including another blog post that shows you step-by-step how to import and export Pipe Networks from Civil 3D and Autodesk Storm and Sanitary Analysis.

Give it a try and let us know how things are going!
Hi Wendy... the second link pointed out the problem I am referring to
Importing and Exporting Pipe Networks from Civil 3D 2019 and Autodesk Storm and Sanitary Analysis
See... only energy and hydraulic grade line info is transferred from SSA - via STM - to Civil 3D pipes. Q and V values - even though available in SSA, are not transferred to Civil 3D pipes - the responder refers to missing "placeholder" - probably in Civil 3D pipe objects. Typing in the values can lead to many errors in the production drawings - there must be another way?
Hi @kevin.bza,
Thanks for the feedback. I researched this internally and found that the Q and V values can be calculated in Storm and Sanitary Analysis. Unfortunately, these values are not transferred to Civil 3D. The Hydraflow Storm Sewers file (.STM) as the interop format – but this does not store computed Q. Instead it stores the data to compute flow (i.e. catchment area, TOC, runoff coefficients, etc.) The STM file does store velocity – at both the up and down end of each pipe… but Civil 3D does not store velocity as a property. Therefore, neither value comes back to Civil 3D.
Here are other threads with a similar question and @Matt.Anderson answered it and explained it really well.
see attached DWG ... I am trying to use Property Set values to represent Q and V (from SSA) - as C3D Pipes do not have placeholders for Q and V - it works correctly with pipe labels in plan ... but we need those values in a Profile View Band... I dont mind if its a Profile Data band or pipe network band ... Please help! : (
Accepted solution
Hi @kevin.bza
Use an expression to create velocity and flow. See this article for. building the expression for flow, Q
See these threads.
After you've the expressions, use Pipe Profile Bands instead and have it displayed in the profile band.
See this screencast by @TrainingNode-01
Let us know how it goes...
