python - How to pick the right LoadFamily function in revitpythonshell -

revitpythonshell provides 2 similar methods load family.

loadfamily(self: document, filename:str) -> (bool, family) loadfamily(self: document, filename:str) -> bool 

so seems return values different. have tried calling in several different ways:

(success, newfamily) = doc.loadfamily(path) success, newfamily = doc.loadfamily(path) o = doc.loadfamily(path) 

but bool back. want family too.

you can @ overload looking this:

import clr family = clr.reference[family]() # family object reference (not set instance of object!) success = doc.loadfamily(path, family)  # explicitly choose overload # family revit family object , can used wish 

this works creating object reference pass function , method overload resultion thingy knows 1 for.

working under assumption list of overloads shown in rps same order appear - think pretty safe assumption make, can this:

success, family = doc.loadfamily.overloads.functions[0](path) 

and will, indeed, return tuple (bool, autodesk.revit.db.family).

note, has happen inside transaction, complete example might be:

t = transaction(doc, 'loadfamily') t.start() try:     success, family = doc.loadfamily.overloads.functions[0](path)     # stuff family     t.commit() except:     t.rollback()
