How do the Storm-Sewer products (StormCAD, SewerGEMS, CivilStorm, SewerCAD) integrate with InRoads, PowerCivil and GEOPAK?


Below are details on how StormCAD integrates with InRoads, PowerCivil, and GEOPAK:


An InRoads Storm and Sanitary file can now be imported/exported inside of the standalone platform of the products via File > Import/Export. When using Microstation-integrated version, you can do this via the product menu (such as StormCAD), then Project > Import > InRoads. This functionality was added in version V8i SELECTseries 3. In version, the ability to do this in the AutoCAD platform was added, along with the ability to retain/persist relevant calculated results during export and persist curved pipes (bends will be added in the StormCAD model). All subsequent versions include this functionality as well.


You can now use storm-sewer products within the PowerCivil for Americas environment. You will see a shortcut such as "StormCAD for Powercivil for Americas". You will be able to lay out and compute your storm-sewer model, while using the PowerCivil tools. Also, while you are in the PowerCivil for Americas platform, you can import/export a GeoPAK drainage file via the product menu bar > Project > Import.  All subsequent versions include this functionality as well.


When using storm-sewer products inside of Microstation with a GEOPAK license, you can import/export a GEOPAK drainage file, via the product menu bar > Project > Import > GEOPAK Drainage.

Or if exporting to GEOPAK drainage file option is not available inside Microstation-integrated version, then you can:

  • Either directly open .dgn file of storm-sewer model in GEOPAK or import .stsw file from Subsurface Utility menu in GEOPAK.
  • Make the project active by doing an activity like computing the storm-sewer model, go to Subsurface Utility>select Project>Export>GEOPAK drainage.
  • You are prompted to create a .dlb and then prompted to create a .gdf.

For issues activating the GEOPAK license in MicroStation-integrated, please reference the following link:

How do I activate a GEOPAK license inside StormCAD for MicroStation? 

All subsequent versions include this functionality as well.

NOTE: With PowerGEOPAK, the integration process is not automated. You will need to manually change the configuration files in order to see the integrated products.
