Export DWG From Template File (Post 3)

Revit
1

I’m trying to export DWG’s with options provided from a template file and unfortunately the python script that I am using (originally @Konrad_K_Sobon’s) is throwing a:
AttributeError: ‘UnkownElement’ object has no attribute ‘GetDWGExportOptions’ error message.

I know it isn’t a problem with the Method, because it is defined in the API.

Therefore, I’m assuming that I’m missing something when I try to get the ExportDWGSettings element into the python script.

Anyway here’s my very lightly modified Python Script, with the line in question being
options = IN[5][0].GetDWGExportOptions()
following “def ExportDWG” near the bottom (I wish there were code line numbers :slightly_smiling_face: #site-feedback )

Have you tried unwrapping the ExportDWGSettings object?

I swear I had tried that before, but that did the trick, Thanks.
