Flagship Service

Built by an Engineer,
for Engineers

Proven on 1,000+ real construction drawings from the Kia Kazakhstan automotive manufacturing plant (2023–2025). Unlike generic translators, this platform preserves Engineering Intent — not just words.

Structural member specs, joint details, tolerances, material callouts — information where a mistranslation becomes a safety incident — handled with field-verified accuracy.

Process

Three Steps.
One Translated Drawing.

Upload your file and receive a fully translated, AutoCAD-compatible DWG in minutes.

01
Upload Your DWG

Drag and drop your DWG file. The platform analyzes the drawing structure and extracts all translatable text — while every layer, block, and geometry stays untouched.

02
AI Translation

A multi-stage AI engine translates each string with engineering context awareness. The adaptive glossary ensures consistent terminology across your entire project.

03
Download Result

Translated text is placed back at the exact entity positions. The output DWG is fully compatible with AutoCAD and all major CAD platforms — ready to use immediately.

Security & Deployment

Your Drawings Never
Leave Your Environment

For defense, semiconductor, and advanced-manufacturing facilities, engineering drawings are confidential assets — they cannot be sent to a public translation service. Sinbiroum ships in two operating modes: an Online Mode for general, non-sensitive drawings, and a Secure Mode that uses only an LLM endpoint as its language backend — with no third-party translation APIs in the processing pipeline. This is the same configuration that processed 1,000+ drawings on the Kia Kazakhstan plant project, entirely within the client's intranet.

🛡️
Operating Modes
Secure Mode & Online Mode
Choose per project sensitivity
Secure Mode for confidential projects (LLM-only backend); Online Mode for general drawings via the managed cloud demo at /dwg-trans/.
🔒
Secure Mode
LLM-only Pipeline
No third-party translation APIs
In Secure Mode, the only language-model dependency is a single LLM endpoint — drawing text is not routed through external translation services.

What Engineers Say

Feedback from professionals who use the platform in real projects.

★★★★★

"We translated over 1,000 Russian structural drawings for the Kia plant project. What used to take our team weeks now finishes in a day. The time savings alone justified the switch."

D. Park
Construction Project Manager · Automotive Plant, Kazakhstan

★★★★★

"What surprised me most was the accuracy on structural terms — member specs, weld callouts, and material grades came through correctly. And the DWG opens perfectly in AutoCAD without any cleanup."

S. Yoon
Structural Engineer · Steel Fabrication, Korea

★★★★☆

"Multi-language support is a game changer for our international projects. We can now handle Japanese and Vietnamese drawings too. Looking forward to Chinese support being added."

M. Tanaka
Plant Design Engineer · EPC Firm, Japan

★★★★★

"Every layer, block reference, and dimension stayed intact after translation. As an MEP engineer, I was worried about losing annotation positions — but nothing moved. Impressive."
