A digital studio & brand workshop building the stuff people remember

We team up with ambitious founders, scale-ups and brands to turn strategy into products, identities and experiences that actually ship.

Architecture & Core Principles

The model authors, code generates.

Deterministic verification over generative guesswork — engineered for mid-market discrete manufacturing.

Harness & Verify Pipeline

Frontier Claude models read full drawings and author build123d scripts. Pure OpenCASCADE code generates geometry. The model never touches solid B-rep directly, ensuring true CAD parametric integrity.

Size & Form Gate Referee

Dual-gate verification: size gate measures stated values along axes; form gate projects silhouettes to score 0.5 mm/px IoU. Guessed sizes are catalogued by name and value — no hidden hallucinations.

ASME Y14.5 & ISO Review

Deterministic rule engine evaluates structured records against versioned rules with per-field confidence from orthogonal signals. 3-way correction attribution: rule wrong, extraction error, or approved deviation.

Air-Gapped & Zero Retention

Customer drawings and IP never train public models. Zero-retention API endpoints, signed DPAs, and a self-contained 72.7MB demo bundle running fully air-gapped on factory networks without external keys.

Archive Diagnostic & FLIP Pilot

Deploy Drawing Intelligence on your factory archive.

Book a two-week paid archive diagnostic ($3,000–$5,000) or request early FLIP conversion access. We take your legacy prints and deliver duplicate reports, geometric clusters, and verified 3D STEP solids.

VERTEX BUILDS AI IN ENGINEERING. ITS FIRST PRODUCT IS FLIP: ANY ENGINEERING DRAWING IN — DWG, DXF, VECTOR PDF, SCANNED PRINTS, OR A PHONE PHOTO — AND A CHECKED 3D STEP SOLID OUT IN MINUTES.

THE MODEL AUTHORS; CODE GENERATES; CODE DECIDES. EVERY STATED DIMENSION IS MEASURED ON THE SOLID, EVERY GUESSED SIZE IS NAMED, AND AN HONEST VERDICT IS GIVEN BEFORE ANY METAL IS CUT OR SCRAPPED.

── THE_FLIP_PIPELINE ─────────────────────────────────────────────
* 01 // UNIVERSAL INPUT INGESTION
ANY SHEET GOES WHOLE TO THE AGENT WITHOUT LOSS OF CONTEXT. NATIVE DWG, DXF, HIGH-RES VECTOR PDF, CRUMPLED SHOP SCANS, AND MOBILE PHONE PHOTOS.
[NATIVE DWG/DXF] [VECTOR/RASTER PDF] [SHOP PRINTS] [PHONE CAPTURES]

* 02 // HARNESS & VERIFY (AGENT AUTHORS, KERNEL GENERATES)
A CLAUDE AGENT READS THE FULL SHEET AND WRITES A BUILD123D SCRIPT. CODE EXECUTES OPENCASCADE TO GENERATE A SINGLE WATERTIGHT B-REP SOLID.
[ZERO TRIANGLE MESHES] [EXACT B-REP SOLIDS] [STEP / CAD EXPORT]

* 03 // FOUR HONEST VERDICTS
WE DO NOT HIDE FAILURES BEHIND DRAFTS OR REFUSAL THRESHOLDS. FLIP SHIPS AN HONEST VERDICT ON EVERY RUN:
- VERIFIED ........ 0 FAILED DIMENSIONS; CONFIRMED AGAINST ANSWER KEY
- NEEDS REVIEW .... NAMED DEFECTS IN PLAIN WORDS (E.G. 'R3 FILLET MISSING')
- FAILED: NO MODEL  MULTI-BODY OCCURRENCE OR VIEW EXTRACTION CORRUPTION
- FAILED: SERVICE .. PROVIDER TIMEOUT (USER NOT CHARGED)

* 04 // THE 'WHAT FLIP GUESSED' LEDGER
WHEREVER SIZES ARE UNSTATED (HEX DEPTH, UNNOTED RADII), FLIP NAMES EVERY CHOICE OPENLY IN A DEDICATED PANEL INSTEAD OF SILENTLY HALLUCINATING.

── ENTERPRISE_SUITE ──────────────────────────────────────────────
- FLIP 2D->3D — ON-DEMAND STEP SOLIDS FOR CAM PROGRAMMERS & LEGACY PRINTS.
- ARCHIVE SEARCH — GEOMETRIC RETRIEVAL ACROSS 10K+ DRAWINGS TO STOP RE-MANUFACTURING PARTS ALREADY SITTING IN BINS.
