Recipe 9 — Bake Geometry

What: Bakes Grasshopper geometry into the Rhino document on a named, colored layer using Model Object + Model Layer (Rhino 8+).

Zone Map: [Layer_Panel][Color_Swatch] → [Model Layer] → [Model Object] ← [Geometry] → [Cache]

Components

Step	Component	Config	Notes
1	Panel	Layer name as text (e.g. `"2D::Outline"`)	Nested layer names use `::` separator
2	Swatch	Pick desired layer color	Drives the baked layer’s display color
3	Model Layer	default	Takes name (Panel) + color (Swatch) → layer definition
4	Geometry	Right-click → set geometry type	Curve, Brep, Mesh — whatever you want to bake
5	Model Object	default	Takes geometry + layer → baked model object in Rhino
6	Content Cache	default	Caches the baked result so it persists across solves

Output

Baked Rhino objects on the specified layer. The Content Cache ensures the geometry persists in the Rhino document without re-triggering a full solve.

Typical Next Steps

→ After any modeling recipe (0–8): swap a preview endpoint for this bake pipeline to commit geometry to the Rhino document · Change the Panel text to organize baked output into separate layers (e.g. "Structure", "Facade", "Mesh") · Combine with Recipe 6 (Dispatch) to bake two subsets to different layers.
