Hi, I’ve been trying to use the Dimension ByReferences node from the Genius Loci package, but the references from the linked duct elements always lead to null output. I’ve use the Convert Linked Reference node to process the element reference already but still no success.

The same setup will work if the element reference is from the active model.

Appreciate any suggestions!

@dh2 ,

be aware when your dimension are refered to Linked elements, that dimensions get lost by updating the file!

We managed that with design freezes

Hi @sovitek, yes, and the node will use the active view by default. 🙂
