I'm using C3D 2014. I created a pipe network, exported it to Hydraflow Storm Sewer, perfermed an analysis, and have HGL/flow data. When trying to import the .STM file, nothing happens. Here's what it does:
1) Import .STM into a Blank/New Drawing -> Creates a pipe network with correct IE, Size, and HGL/Flow Data
2) Import .STM into design drawing -> Choose to Update Network -> No change in network (IE, HGL, etc.)
3) Import .STM into design drawing -> Choose to Create a New Network -> Does not create a new network
Anyone else have this issue? I've tried closing C3D, and checking, still no change.
In case anyone else is having this issue, I might have found a work-around.
1) Import your completed/analyzed .STM file into a blank drawing
2) Check for HGL info
3) Export your pipe network to LandXML
4) Import that LandXML into your original design file
I tried this on a small "test" network, and it seemed to work.
