One runtime.
Two ways to reach it.
Engineering files are not text. Flatten a drawing into a caption and the geometry — the B-rep solids, the dimensions, the tolerances, the constraints — is gone before the model ever reasons about it. So the answers come back plausible and unusable.
Rowe keeps the geometry. Your STEP, IGES, DXF, PDF, or SVG file is parsed into a structured cad_scene — solids, faces, entities, dimensions, annotations — and the model reasons over that. You get typed JSON back: measurements, relationships, issues, and comparisons, each traceable to the geometry it came from.
- Four Echelon
- extraction, spatial reasoning, API, and deployment.
- Four Cad
- upload, inspect, compare, and export.
- Rowe 1.0
- structured scene in, typed reasoning and evidence out.
Model
Rowe 1.0
The spatial reasoning model.
One endpoint. Send a structured scene and a task type; get typed spatial output, usage, and a request id back. Rowe reasons over geometry that has been kept intact rather than described in prose.

Four Cad
CAD and drawings, made agent-readable.
The reference workbench for people, and the extraction API underneath it. Upload a STEP, IGES, DXF, PDF, or SVG file and get structured JSON: entities, dimensions, annotations, solids, and faces. No OCR anywhere in the path, so a dimension is read, not guessed.

- STEP / STP
- 3D solids, faces, exact volumes
- IGES / IGS
- 3D solids and surfaces
- DXF
- 2D entities, dimensions, annotations
- Vector drawing entities and annotations
- SVG
- Vector drawing entities
- OBJ / STL / JSON
- Point clouds and meshes, browser-side
What does not
- SolidWorks native (.sldprt / .sldasm)
- Export to STEP and upload that. The API returns HTTP 415 — deliberately, not as a bug.
- Latency SLAs
- The status page reports single-probe latency samples. We do not publish p50/p99 guarantees.
- Head-to-head accuracy claims
- We publish our own eval methodology and error bars. We do not claim to be best, superior, or state of the art.
- Draw.io and other diagram formats
- There is no parser and no normalized contract for them today. On the roadmap, not shipped.
Start with one call.
Get a key, send a file, read the JSON. Pricing is a $49.00/month base plus metered spatial tokens, and only successful requests bill.
