Rooftop package unit

rooftop-package-unit dresses asset:rtu — and nothing else. Appearance is invisible to the drawing set, so adding this changes no plan, no section and no elevation.

The reference. AI-generated, not bimtex output — the authored input this body was written against.
$frame
$surface

This definition leaves $frame and $surface open, and a look line fills them. Every combination is one body — same geometry, same selector, same sheets — so the block below rewrites itself as you pick. Only materials are slottable: a size would have to agree with the plan, so it stays on the entity.

Paste this

Every part: the 2 materialdefs the body resolves to, then the definition. Copying the lookdef alone still compiles and still validates — it just renders grey.
