So we have some windposts in the masonry wall. They’re just RHS sections.
But do we model them as structural framing, or as some kind of custom-made generic model?
Logic says they’re a length of RHS with structural properties, so they’re structural framing. But logic also says they’re wall-based.
How would it be if you could embed a piece of RHS structural framing inside a wall-based family? Just like you can embed a shared window or door. Then the family could be both structural framing and wall-based at the same time: The structural framing element would give you all the structural properties, and the wall-based wrapper would give you the sticks-to-the-wall feature.
