Data-shapes node convert output type?

[TexxK]

I’m trying to collect Revit categories from a selection box using the UI.multipleinputform++ node to run a very simple interference check. My problem occurs when filtering out which categories of elements to run the Tool.IntersectionChecker with. How do I go from the Data-shapes output to a Revit Category?

Try this having a look at this post:

Filter loaded families for better user experience in Dynamoplayer?

@KennethVeithElgaard Absolutely. It’s a great package, although takes some time to understand, so I suggest reading the website and following some examples. Use the UI.dropdown data in conjunction with the UI.multipleInputForm++ (as below) You’ll need to convert the list of family types to a list of strings before connecting to UI Dropdown node. Then on the other side of the UI node use the “FamilyType.byName” node. (no need for the list.create node) [image]

The issue was that I was using Revit Categories instead of Category names earlier in my script, stupid… Resolved
