Hello. New to Dynamo here so go easy please. I am hoping that I can use Dynamo to achieve the following - opening each family loaded into a model, ungrouping all elements, purging, and loading them back into the model. Am I being too optimistic? This is because a job we’re working on has got 2300+…

I found some time to take a look at the reloading: The IFamilyLoadOptions implemented in python: class FamilyOption(IFamilyLoadOptions): def OnFamilyFound(self,familyInUse,overwriteParameterValues): overwriteParameterValues = True return True def OnSharedFamilyFound(self, sharedFamily, f…

They are, and I didn’t really expect to have work done for me, was quite genuinely wondering whether it’s the type of thing it would do or not. Thanks for your help though!

OK, this topic could possibly go further, so here is a way to get started: [image] Group.UngroupElements is from Rhythm or Clockwork. Please use with caution and do some preliminary tests (don’t run in automatic or several times and use Undo in Revit if needed)

Oooo. Thank you for this, will see how I get on and report back!

"Usually, proceeding step by step leads to results" Usually not. Thus, your next post about ungrouping is a good example - it works only with elements in the model. The original topic is much trickier - how to process families and work inside them as we do in models. Look fwd to gurus.

[image] Einar_Raknes: I 'm not sure if it’s possible to reload the documentes with Dynamo. You can use IFamilyLoadOptions Interface in Revit API IFamilyLoadOptions Interface

Yes, you have to use that as an argument in one of the overloads of the LoadFamily Method . It requires that you create a custom class and maybe utilize StrongBox type to handle the out attributes in that class’ methods. That shouldn’t be any problem, but I had some doubt about the transactions, but …

@Einar_Raknes definitely but am snowed under with other work at the moment! I will report back once I find the time to dedicate to this. Many thanks!

There was a similar question on how to edit multiple families quite a while ago, that was answered here: [image] Modify Room Calculation Point toggle (Builtin Parameter) Packages Jeff, Does this work for you? [Capture]Here is how this works. You take a family that you w…
