FilterType is from the Elefront plugin, which I installed at some point to evaluate but never used so I forgot I had it. Apparently it doesn’t consider an “Untrimmed Surface” as a Brep. And doesn’t accept a list of types on its ‘T’ (Object Type) input (as a logical “OR”):
As indicated by the tooltip when you mouseover the ‘T’ input, it is optimized for connecting a Value List, which it populates automagically with the supported choices. Again, it works only as a ‘Dropdown List’ (single value only!), not as a ‘Check List’ with more than one geometry type selected.
