I have the Advance Steel addon installed in Revit and when I import a .smlx I get the Unkown types dialog box with the family name and symbol name blank.
When you click on Load Family button and browse to the language. I only have to options Route Analysis and Structural Precast.
Am I missing something from the Advance Steel Add-on? Is there a better way to import a Advance steel model into Revit? I'm using Revit as a intermediate software to get to Risa. Does anyone know how to get from Advance steel to Risa?
