Workflow: To Import a Catchment Model into Autodesk Civil 3D

Use this workflow after you have worked with a Autodesk Civil 3D model in Storm and Sanitary Analysis.

Export your data from Storm and Sanitary Analysis using the Hydraflow Storm Sewers (STM) file format	The Hydraflow STM file is used as a data transfer file between Autodesk Civil 3D and Storm and Sanitary Analysis. See "Exporting Hydraflow Storm Sewers Files" on page 498 of the Storm and Sanitary Analysis User's Guide.
Import the STM file into Autodesk Civil 3D	The edits you made in Storm and Sanitary Analysis are preserved on import back into Autodesk Civil 3D.
