SOLID.ByUnion to PYTHON

Revit
, , ,

Good morning.
I am trying to replicate in PYTHON the “SOLID.ByUnion” NODE where I can join all the solids inside the lists and return the united solid, thus maintaining the original number of indexes in the list.
Could someone please help me.

You just need to iterate over the sublists if I am understanding correctly.

Not at my PC but try this:

#after standard imports
listOfListsOfSolids = IN[0]
unionedSolids = [Solid.ByUnion(listOfSolids) for listOfSolids in listOfListsOfSolids]
OUT = unionedSolids

They are applying your recommendation but it returns an error, why?

You’re importing both the Revit Solid class and the Dynamo Solid class, so not just the standard boilerplate.

This means that you need to call out which ‘Solid’ you’re using, Dynamo’s or Revit’s. Calling out the namespace as a prefix (typically Revit.DB. or Geometry) will ensure you always use the right namespace. However…

You also have an alias of DS for the Dynamo Geometry class, which is a common way of ensuring no namespace collision issues while ensuring you always get Dynamo’s geometry library. So you need to use that as your prefix.

So instead of typing only Solid to call the Dynamo Solid class you would use DS.Solid instead.

Thank you very much for your time, I still need a lot of practice to be able to identify the errors well… thank you
