If you're interested in a gentle introduction to OpenRoads Subsurface Utilities (StormCAD, CivilStorm), we (Bentley Institute) finally made some introductory classes that don't assume you are a Roadway Designer.
The OpenRoads Designer - Subsurface Utilities Learning Path starts with a Navigating the OpenRoads Interface class, followed by an Evaluating Subsurface Utilities class. In an hour, you be able to distill everything you could distill from a StormCAD or CivilStorm file.
QuickStart for Terrain Display makes you a master of evaluating Terrain (contours, flowlines, etc.).
The remaining classes cover the OpenRoads flavor of doing things you already know how to do. You'll be an expert in no time.
Thank you so much
