Type your rooms and dimensions — or describe your building in a sentence — and Allspace generates an exact, walkable 3D model, with multiple floors, stairs, doors and windows. Already have a clean CAD plan? Import that too.
Works best on crisp CAD / vector exports · JPG, PNG, WEBP · Max 16 MB
No plan handy? Try a sample:
Beta — importing detects walls from the image, so messy scans or heavily-annotated plans may only partly reconstruct. After generating you'll see exactly which walls were found. For exact results, use Type it in.
Generation
Interior elements
Use “Force floor plan” if a blueprint or coloured plan isn’t detected correctly.
Scale
Sets real-world metre scale on the exported model. Assumes 96 DPI scan.
Describe it (optional)
Lists the rooms and arranges them for you — then drag them around below to fine-tune. Understands room names and counts (sizes default to typical, adjust by dragging).
