Dear Danny,
Thank you for your note.
I don't understand exactly. You mention loading "the new wide flange family symbol". That should be one call to load the family with all its symbols. You say "loads it multiple times". Why?
The change request REVIT-68222 [As Revit API user, i need ability to load more than one symbols via LoadFamilySymbol(String, String) method.] we discuss above is for the case when you have a large family definition containing many types and you wish to load a small subset, but significantly more than one.
The single symbol and all symbol cases are already covered.
From your description, I do not see how this affects you at all.
You sound as if you would like to prevent Revit from loading one or all symbols multiple times.
And so you should.
Please clarify.
Cheers,
Jeremy
