Choose how this project starts. Each mode is explicit about what the source of truth is.
No file needed. A structured brief — type, plot, floors, rooms, style — becomes a concept model with quantities and cost.
Upload IFC, DXF, DWG, PDF or an image. The file is parsed deterministically and you review exactly what was extracted.
Use an existing drawing as the base and tell the AI how to transform it. Parsed and AI-inferred geometry stay distinguishable.
Design from constraints: rooms, areas, setbacks, adjacencies. Compare scored candidates and convert one into the model.
