I am trying to get all categories from a linked file. It works when I use OOB revit nodes but I could only retrieve 1 category at a time. I tried getting all categories from data-shapes packages but it didnt work.
I thought it might be due to the object data type, check out the image below.
“Revit.Elements.categories” VS “Autodesk.Revit.DB.Category”
Input “Category” at archi-lab custom node is expecting Revit.Elements.Category. The easiest way is to use Category.ByName node after “Category name(s)” and connect the values to “Category” at custom node. Cheers!
