API does not load curtain Panel RFA files

[arun.shankar]

I am trying to load a curtain panel RFA file by invoking the Document.LoadFamily() method. However, Revit gives an error message " Curtain wall panels may not be loaded into a family" and does not load the family. Is there any other way to load an RFA file with a curtain panel using the DotNet Revit API? Thanks.

I have attached an RFA file that shows the problem.

I was able to load the file you supplied without issue. Are you wrapping the call inside a transaction? What version of the API are you using?
