Engineering geometry for programs
where the review cycle is the bottleneck.
What we are actually solving
Defense hardware programs carry the same geometry problems as aerospace, with longer review chains and stricter provenance requirements. Every Rowe answer is traceable to the structured scene it was computed from, which is what makes it reviewable.
How teams use it
01
Fit and clearance review
Interference, envelope, and access checks against structured B-rep geometry, with the measurement attached to every finding.
task_type: fit
02
Configuration comparison
Diff configurations and revisions and get an explicit list of what geometry moved.
task_type: compare
03
Auditable output
Typed JSON with request ids, usage, and a versioned extraction schema — so a finding can be re-derived rather than trusted.
task_type: understand

Files are parsed into a structured scene and reasoned over. Uploads are processed for the request, not retained as a library — persist the outputs on your side. Data retention
What we do not claim
Four Echelon is a commercial API running on commercial infrastructure. There is no accreditation, no classified enclave, and no air-gapped deployment today. Ask us before assuming a compliance posture.
Try it on one of your own files.
The quickstart is a single curl call. If you would rather see it before you build against it, upload a part in the workbench.
