AHA !
I Found how to filter by object type, but then it took me a while to guess that “Model Block Instance” which is the object type as labeled by the new components is NOT the text value to use, but rather just “Instance”.
Now if I try to use the presets in the “Key” input of the “Contains” component, this is what would make the most sense :
…but the Key turns out to be just “Name”, and filters by Rhino Name :
I find it kind of silly that I can filter stuff that has this or that print width (Who needs that ???), but I can’t filter by block definition name !!!
Is there some kind of online reference for these new components, or is it just as usual ?
