I have a custom workspace configuration that automatically loads the correct project, user (the person), and interface based on the directory where the dgn file was opened. StormCAD V8i, Civil Storm 8, SewerCAD V8i, Pond Pack V8i, and WaterCAD V8i all load into MicroStation via a project config file. For me, this means I have to constantly change the product load command lines in the project config in order to load any of the above products. Is there a way to set the windows default program associated with dgn to open with one of the above software? I would like the end user to right click on a dgn file, move the cursor to "Open With" and have options for the software listed above. By doing so I could tie MicroStation into the Corporate workspace and everything would be copacetic.
