I am trying to assign a list of wide flange column sizes to my Revit model using the Element.SetParameterByName node but I am having trouble selecting the correct family. I am currently using the FamilyType.ByName node but it is returning the first family type that it finds (i.e Steel-W-Wide Flange). Is there a way to read my list of W44x335 members and select the Steel-W-Wide Flange-Column family in lieu of the Steel-W-Wide Flange family? Thanks for your help.

So you’re trying to change a family… By changing a parameter?

Yes. I figured it out with the following image below. Thank you!

My concern now is how do I assign a Steel-HSS-Hollow Structural Section-Column if my list contains both HSS and Wide Flange column members?
