Grasshopper: Clip & Section

Parametric Sections

Grasshopper now speaks Rhino’s drafting language: clipping planes, sections, and 2D drawings are now native, parametric objects. Place and drive real Rhino clipping planes parametrically, control exactly which objects and layers they clip.

Parametric Drawings

The new Create Clipping Drawing component goes further: one component turns any clipping plane into a complete 2D drawing: section fills, hidden lines, silhouettes and more, delivered as a block that updates when your model does. Change the design, and the drawings follow.
