Cadio for Grasshopper
Describe parametric relationships in plain English, or feed in scan data for parametric reconstruction. Cadio brings text-to-CAD and scan-to-CAD into Grasshopper.
CadioWhat You Can Create
Visual Programming with Prompts
Describe the parametric logic you want and Cadio wires up the Grasshopper components—sliders, series, domains, and data trees.
Algorithmic Patterns
Generate Voronoi patterns, attractor fields, and paneling systems by describing the design intent.
Live Parametric Control
Ask Cadio to add sliders for key parameters so you can fine-tune the design interactively.
Scan-to-CAD inside Grasshopper
Parametric reconstruction from scan data — feed a mesh into Grasshopper and Cadio generates a parametric definition that rebuilds the geometry with editable parameters. Scan-to-CAD will be available when Grasshopper support launches.
