Play mat

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

The build. Made here, now, by the same interpreter a model gets.

Play mat, shown as a photorealistic visual reference — **The reference.** AI-generated, not bimtex output — the authored input this body was written against.

$surface:field

$surface:road

$surface:patch

$soft

$frame

This definition leaves $surface:field and $surface:road and $surface:patch and $soft and $frame 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 5 materialdefs the body resolves to, then the definition. Copying the lookdef alone still compiles and still validates — it just renders grey.
