Hello all! I am quite new to Dynamo, so any advice is appreciated. I want to select all instances of a fabrication part, however when I select the part and pull the family name, then feed that name to the Family.ByName node (which pulls the correct family name), it cannot find any matching families…

Jacob, Updating this thread with the information you send over DM: I took your advice and disabled all addons, as well as switched the run style from automatic to manual. It worked! Thank you very much. It appears that the main issue was not the addons but the automatic run setting, as when I swit…

Hi, When you select an element, you want to find out how many of that element there are, if I understand you correctly. Can you try this [1]

Volcan, Thank you for the reply. I do not want to just find out how many there are, but to select all of the same family. What I find strange about my node configuration is that it pulls the family name from the current document, and when I go search that same document it says that a family of that…

With this, you can take not only how many, but also those elements and process them. Archi-lab.net package [image]

Volcan, For some reason, Archi-lab will not appear under the Addons list after installing, despite installing with no errors. Does it support the latest version of Dynamo? I am currently using the latest build for Revit 2022, which I believe is version 2.12

You need to install the version of Archi-lab for your Revit version. This is the version ending in “22” for Revit 2022, “21” for Revit 2021, and so on. See the link above for more info.

Thank you all for the help. However, unlike your example volcan, my element.type appears to be pulling the element type, not the family type. [image] with the error "Warning: ElementQueries.OfFamilyType expects argument type(s) (Revit.Elements.FamilyType), but was called with (Revit.Elements.Eleme…

See what parameters you have for the element (not the element type) via an element.parameters node. Fabrication parts are very unique as they aren’t really Revit elements the way most are, so you may have to use another method of collection entirely. If you post a sample model I might be able to di…

Right, I was wondering if fabrication parts had anything to do with it. I have been trying to come up with a workaround, and think I may nearly have it. I am trying to tag all selected elements (those elements being the fabrication families I have been trying to select), but once I try to run the ta…

We can keep it in this thread for now - but we need to include how you’d elected the instances as well in the post marked as a solution. Can you post an RVT with a half dozen or so fabrication parts? Really simple model, nothing crazy. I don’t want to just make one and assume the wrong version of R…

You can also use this method if you are having trouble installing the Archi-lab package.
