Caddisfly is a Grasshopper add-on for Rhino that automates the design of free-form and complex structures, from concept through to fabrication-ready kits of parts.
It targets architects and structural engineers working on space frames, grid shells and facade systems, applying AI-driven design logic, code checks, and cost/time estimation.
Caddisfly is a Grasshopper add-on (plug-in for Rhino) developed by Ardaena for designing and delivering automated kits of parts for free-form and complex structures. It covers the workflow from conceptual design through analysis to fabrication-ready 3D output, including single- and double-layer space frame structures, grid shells, and facade systems. The tool applies AI-driven design logic, including building-code compliance checks, DfMA (design for manufacture and assembly) reporting, and cost and construction-time estimation, and generates 3D elements ready for CNC fabrication. It is built using Python and C# for flexibility across components. Ardaena, the firm behind Caddisfly, also uses the tool internally on its own computational design and engineering projects, such as the Ava Center skylight. There is no self-serve download or published pricing; access is arranged by booking a demo directly with Ardaena.

Reer
Reer is an AI-powered workspace designed to bring intelligent assistance directly into CAD and BIM workflows.
It helps architects, engineers, and designers create, analyze, coordinate, and modify models using natural-language instructions. By working across platforms such as Rhino, Grasshopper, and Revit, Reer automates repetitive tasks, connects fragmented tools, and supports faster problem-solving.
The platform helps teams explore ideas, streamline design processes, and improve efficiency across complex projects.
Grasshopper 3D is the visual programming environment included with Rhino for computational and parametric design. Architects, engineers, façade specialists, and fabricators connect components on a canvas to generate geometry, process data, and test design variables without building every option manually. It works directly with Rhino’s modeling environment and can extend into BIM, analysis, optimization, and fabrication workflows through official integrations, scripting, and plugins.
Finch is an AI-powered generative design platform for architects, integrating with Rhino, Grasshopper, Revit and Autodesk Forma. It generates and compares floor plan and unit-mix options in early-stage design, producing code-aware layouts and BIM-ready geometry.
