I created this post because I wanted to help clear up some of the confusion when DynamoBIM users want to select all the Loadable Revit Family Instances using DynamoBIM. Its easy and it only takes 2 nodes but the naming found within each node could be very confusing. So first add a Family Type selection node, select the family type, and then wire that to either the FamilyInstance.ByFamilySymbol or All element of Family Type node and click run... THATS IT!...Well...there is still the issue of the naming.... This process is summarized in the image below and notice... from the image it is clear that the nomenclature used in DynamoBIM is very confusing because two different words could mean the same thing... The question is....why is DynamoBIM like this? I have no idea. Stay tuned to this blog.... I will try my best to help clarify confusing naming conversions, in future posts, as I encounter them.
