Can Bentley Map files be used as a source file in ModelBuilder?
If you are using a platform in which the Haestad product is available and Bentley Map is activated, you will be able to use a Bentley Map file in ModelBuilder. This functionality will be most common in Subsurface Utilities / OpenRoads, which integrates the Bentley Haestad storm and sewer solvers in the Bentley Civil products. However, if you add the Haestad product to your workspace for another product that uses Bentley Map, such as OpenUtilities, this functionality will be available as well.
