Team BMTR, NCSEA Big Build SE Hackathon 2026. Turn a framing sketch or an architectural PDF into a starting RISA-3D model, instead of retyping every node and member.

The team app

By Afshin. Runs on your PC.

  • Reads a sketch photo or a PDF plan with a Claude agent that checks its own drawing and revises
  • Framing editor with W-shape sizes
  • Writes a native RISA-3D .r3d model and opens it in RISA
Get it and run it

Truss to RISA

By Olu. Runs in the browser; the Claude drawing reader runs on claude.ai.

  • Fink, Howe/Pratt, flat-chord or mono trusses from parameters, or read from a drawing or photo with Claude
  • Steel or wood members, pin/roller/fixed supports, top and bottom chord unit loads
  • Writes a RISA-3D .r3d, repeated along a key plan when there are several trusses
