I am creating a script to delete all families containing a certain “R” prefix. By using Clockwork’s “All Families of Category”, I can select and filter and delete easily. However, “All Families of Category” does not work on system families (their disclaimer on it was right), and the same goes for “A…

This works on my end as well to delete Wall Types with names containing a string (it is only showing one element under the Object.Type node because only one of my walls contained “R”): [walltypesstringcontains] If your Elements.Delete node isn’t working, try one from a different package. The one…

The issue is not with the string, the issue is with specifically selecting multiple wall types. All of those posts are simply various methods of selecting multiple elements, not types. When it comes to selecting wall types, my options are limited to only WallType.ByName and Wall Types, both of which…

Try Element.GetType from Wombat Dynamo or Elements.Type from Archilab or Element.Type from Clockwork or the OOTB Element.ElementType node, or even better, Element Types + All Elements of Type, then use a ElementFilter.ByNameContains or ElementFilter.ByNameBeginsWith from Beaker

Is this not exactly what you’re looking for? [image]

No, this causes it to select the placed instance wall elements within the project, not the types themselves. This is proven by running it with delete elements and it will delete the wall instances, but types remain intact.

This is getting the wall types. Deleting them is probably failing because you have instances of these types in the project. [image] EDIT: Tried it out and deleting them actually works for me. It deleted all instances and the type. Which delete node are you using? Keep in mind you have to keep at …

I am using Elements.Delete, which worked on component families, what did you use? See below for method with Element Types, which only deleted wall instances for me, not the type in the project. [Delete]

Looks like I’m not the only one with this problem. This thread did not achieve a solution either. As he said, this solution is not ideal as it requires you to specify each wall. This does not allow for any changes to types within the project, or it will fail or miss new types.
