Private SVG preflight

Catch file problems before material pays for them.

Drop an SVG for a deterministic first-pass review of structural blockers, open geometry, exact same-operation-looking duplicates, physical scale, near-gaps, hidden objects and other fabrication risks.

Your SVG stays in this browser. No file upload occurs. Only privacy-minimized usage events and aggregate result counts are sent — never your SVG or filename.

Evidence, not a promise.

Fabrication Doctor checks what it can resolve deterministically and shows limitations where it cannot. It does not certify manufacturability, material settings or machine compatibility.

How to read it

Blocked is not the same as “bad file”.

BLOCKED

A strong structural or portability problem was found.

REVIEW

A plausible risk exists, but fabrication context matters.

CLEAR FIRST PASS

No known issue was found. You still preview the actual job before production.
