Rook in Grasshopper

Grasshopper is full of repetitive setup — placing components, wiring them, relabelling, cleaning up a tangled canvas. Rook handles that side so you can focus on the logic of your definition.

Scaffold a definition

Section titled “Scaffold a definition”

“Set up a sphere driven by a radius slider, then I’ll build from there.”

Rook places the right components and wires them. You don’t name components or hunt the ribbon — you describe what the definition should do, and take over when it’s set up.

Tidy and reorganize

Section titled “Tidy and reorganize”

“Clean up this canvas — group related components and straighten the wires.”

“Relabel these sliders so I can tell them apart.”

The kind of housekeeping that’s tedious by hand, done in one ask.

Understand what’s there

Section titled “Understand what’s there”

“What does this definition do?”

“Is anything erroring, and why?”

Rook reads the canvas and explains it — useful when you inherit someone else’s file.

Reach for the right pattern

Section titled “Reach for the right pattern”

When you do want help with the logic, describe the effect rather than the mechanics:

“Make the panels smaller near that point and larger further away.”

Rook draws on real Grasshopper patterns — attractors, data trees, remapping — and wires in a starting point you can refine.
