I am making 3D solids and attaching part references to them.
When I make the 3D Solid, attach the reference, and then make the block: the part shows up on the parts list.
However, when I make the 3D Solid, Make the block, and then add the part reference in the block editor: the part does not show up on the parts list. Saving and closing the drawing, restarting does not fix this issue.
Saving the block externally and then reinserting it does cause it to show up on the parts list, but thats a terrible workaround. It also does not count the existing blocks that were inserted from the instance already in the drawing.
Why doesn't the part show up when the part reference is added in the block editor environment?
