CHAAC Plan2Model

AI-assisted pipeline that converts architectural plans (PDF / CAD) into validated building geometry. AI interprets drawing intent while deterministic code enforces geometric truth — calibration, snapping and topology checks — producing simulation-ready gbXML and DXF output.

  • AI interpretation of architectural floor plans
  • Deterministic calibration and geometric validation
  • Interactive 2D review and 3D model validation
  • gbXML export for whole-building simulation
  • DXF export for CAD workflows
Tested for
gbXML on IESVEDXF in NanoCad
Access via the user portal with a business email account.
Exports consume credits — DXF: 0.75 credits, gbXML: 1.0 credit.

Scope notes
gbXML: windows are not implemented yet.
Spaces are intentionally unnamed — a safeguard to enforce human review in the energy model software.
Shading surfaces and adjacent buildings are not produced yet.
Result quality is highly dependent on the quality of the input plans. This tool supports the energy modeler in spending more time on value-adding analysis: detailed physics, operation load behaviour, construction materials and HVAC.

Automation tools developed from real engineering projects. These tools simplify repetitive calculations and report preparation for DGNB, LEED and IESVE workflows.
