Build the tools that build.

Make agents that take a plain request ("a 16×12 deck, two feet up, stairs in front") and return a checked, buildable plan set. You'll own the loop from prompt to geometry to sheet.

• Design tool interfaces agents can't misuse: sandboxed, typed, auditable.
• Build evals that check real outputs: dimensions, code rules, drawing completeness.
• Ship weekly to people who build things for a living.

You have shipped LLM-backed products, write solid Python, and care about failure modes more than demos.

Turn scans, photos and old drawings into clean, editable models. Plane fitting, segmentation, and learned priors that know what a wall is supposed to look like.

• Point clouds and meshes to structured BIM elements.
• Raster plans to vector linework you can dimension.
• Offline-first models that run on a workstation.

Make models feel real in the browser and on the workstation: fast, accurate and beautiful. Shaders, scene management, section cuts, measuring and the camera work you see on this page.

• WebGL/WebGPU, glTF, large-model streaming.
• Precision rendering for CAD: linework, hatches, dimensions in 3D.

Work on the core of Cadnat: geometry, solids, file formats and the native app. Correct first, then fast.

• Modern C++, Qt, B-rep and mesh geometry.
• DXF, IFC, STEP and friends, read and written faithfully.
