Slope Analysis Tool for Architects and Landscape Architects

Grasshopper Slope Analysis Tool

Turn any terrain, surface, or mesh model into a clear, data-driven slope map — directly inside Grasshopper.

This lightweight definition calculates slope angles from mesh face normals, converts them into degrees and colour-codes your geometry based on custom ratio or degree thresholds for accessibility, maintenance, or drainage design.

Includes:

✅ The Internalised test model as shown on the cover

✅ Automatic meshing and fine-tuning via QuadRemesh

✅ Adjustable ratio or degree lists

✅ Fully customizable colour ranges

✅ Optional mesh blur for smooth, presentation-ready visuals

Built for Rhino 8 / Grasshopper. No plugins required.

Perfect for architects, landscape designers, urban planners and anyone who wants quick, meaningful terrain feedback — without leaving Rhino.

This isn’t just another Grasshopper example — it’s a polished design tool built for real projects. It saves hours of trial and error by turning raw terrain into an instantly readable, colour-coded slope map. Architects and landscape designers use it to test accessibility, drainage, and buildability directly inside Rhino. It’s lightweight, fast, and ready to adapt to any site — so you can focus on design instead of debugging math.
