Get Family Symbols From Families

Hi,

1st let us explain what we are trying to do : within a Revit project I would like to be able to evaluate whether families contain symbol lines or not.

This is an exemple of an object in project containing Symbol lines :

This is what we are trying to retrieve.

This is the object in the family editor :

This is where the symbol lines are coming from.

We tested Get Family Symbols From Families.dyf from Clockwork (old version…)

Our questions are :

  • Does this node actually do what we are trying to do? If not, could you tell us which node would work?
  • This node is no longer available. Do you know of the existence of an equivalent?

Family Symbols are actually Family Types. In the Revit API Family Types are called Family Symbols. So the clockwork node won’t do what you are trying to do.
I don’t think you could achieve what you want with the available nodes (custom or OOTB).

I think you’d have to open the family in family editor prior to running the script. In the project environment Revit will only allow you to select the entire family, and as such Dynamo will only allow for the same. You can select the lines in the project environment though.

As always, if you can’t do it in Revit natively, you can’t do it with Dynamo.
