Pyrevit has a family size button… However it seems to be broken for all of our company machines today…
Yes I know a big family can work better than a small family …
BUT - Is it possible to grab the filesize of a Revit family without exporting the Revit families (basically like pyrevit does it)
I tried .Length but AttributeError: ‘Family’ object has no attribute ‘Length’
I’d look into how PyRevit does this directly - the code is open source. There are a few ways, but as far as I know they all rely on putting the document on the disc somewhere (a requirement due to the compression inherent to all Revit file types - they are a form of structured storage after all).
My guess would be opening the family document, saving to a temp file, getting the size of the temp file, and moving onto the next (overwriting the file each time) before eventually deleting the temp file.
I know you can open pyrevit… but I’ve never done it and was hoping someone may already know the answer 
Suppose I’ll have to export 
Thanks tho.
Who has to open? It’s on GitHub, likely here: https://github.com/eirannejad/pyRevit/blob/6aa2c493231f4301125f2570dc5efd644691bbad/extensions/pyRevitTools.extension/pyRevit.tab/Analysis.panel/Tools.stack/Inspect.pulldown/ListFamilySizeCreator.pushbutton/ListFamilySizeCreator_script.py#L4
In particular see line 100 and on.
Ah! You rule! 
And you were right - they are exporting to a temp folder!
Awesome! Thank you
