Just wondering if anyone could help me please, maybe explain.
So I run this simple routine to put the Element ID on each element,
but the thing is I always get an error, although the it works fine,
just wondering why the error occurs and if there is a way to stop it,
you’r getting all instances of FamilyInstance. This would include instances of all families from different categories. Do all categories have the Element ID parameter that you have created?
so its an Instance parameter, I have added to every Family in the model, although I only really need it on certain Familys, Structural framing families, Generic etc. Would this be a reason for the error ?
@a.dyko check what are the collected families in the All Elements of Type node, it is better to collect only the families that you are after if you ask me, try to use Categories node instead, or Category.ByName node with an All Elements of Category node: https://dictionary.dynamobim.com/#/Revit/Elements/Category/Create/ByName
