Curious, I can't get a saved frame to appear either, when i use the library manager
to save my custom Curtain Wall Frame.gsm from the embedded library to an external folder,
AC curtain wall tool could not find it, giving a report that said,
"The selected file is not a Curtain Wall Frame file. Please select a valid Curtain Wall Frame file".
The library manager tool made the file, AC doesn't recognize it. Very odd.
You ask about "no caps" do you mean butt-glazed? ...
