Dear Autodesk
kindly note that there's a very easy way to elevate a 2D drawing that could be added to revit.
this method consists of matching a "layer" (from AutoCAD) to a "structural element" or "material" (from Revit).
In other words, when the user import a 2D drawing from autocad, he assigns for every layer in autocad a structural element in revit (with all the characteristics entered by the user in revit), and the drawing becomes easier and faster.
For more information, you can benefit from the "ETABS" software that uses this features by assigning for each layer an element.
Regards
for any further information
