I really have water on my mind lately as I work on more projects related to the new Autodesk Storm & Sanitary Analysis (former StormNET). Map 3D and Civil 3D subscription customers in North America can download the extension at www.autodesk.com/subscription.
One thing I am working on is documenting some stormwater workflows in Civil 3D, then moving into SSA, then back again.
There are two Civil 3D elements that have bidirectional datasharing with SSA- parcels and pipe networks.
Parcels are shared via LandXML, and I will talk about them another time.
StormNET had the ability to take pipe data back and forth with LandXML, but our development team added something pretty nice. SSA will import a .STM file. That’s the Hydroflow Storm Sewers format that is built right into the Civil 3D user interface.
Find the details about what gets imported and exported and how things are handled, read starting on page 476 of the Autodesk Storm and Sanitary Analysis Users Guide. (Note: the Users Guide installs with the software, but there is also a copy posted the Civil 3D page at docs.autodesk.com. Here is a direct link to download the pdf.)
I recorded a short video showing how to do the export in a little bit more detail. You might have seen me very quickly run through the export in the video I posted the other day.
