Type a sentence, walk through a house: Forge3D Spaces browser CAD

Forge3D Spaces lets users type a sentence like "4-bed duplex with a garage" and instantly generates a furnished 3D house with floor plans, DXF export, and cost estimates. The pipeline uses an LLM to output a structured room program, then a slicing-tree solver from chip design lays out rooms deterministically. The tool runs in-browser via WebGPU with WebGL fallback, and handles real-time editing with cached CSG operations for wall openings.
