The AI copilot for steel detailing

Every steel project on earth, detailed at the speed of software.

fablnx reads your contract drawings, builds the 3D model natively in Tekla Structures, and sizes every connection to AISC 360 — in 4–8 hours, not 4–6 weeks.

fablnx
The starting point 01 — the paper

Every steel building starts as 2,000 pages of drawings.

…and an army of people who redraw every single beam, by hand, before a fabricator can cut steel.

What it takes today

The finished model, taken apart — one drawing at a time.

pages of drawings
The grind 02 — the manual pipeline

Between design and steel, there is 4–6 weeks of manual work.

One project. Dozens of specialists. Zero software in the middle — a drawing packet crawls through five human stages before a single beam is cut.

Why it stayed manual 03 — until now

Software never fixed this — for three reasons.

Lock 01

Unstructured PDFs

Drawings are pixels, not data — nothing to read programmatically.

Lock 02

Expert judgment

The rules that size a joint live in engineers' heads, not a spec file.

Lock 03

Fragmented tools

CAD ↔ Tekla ↔ spreadsheets — no thread runs end to end.

Construction tech grows 14% a year — yet only 12% of detailing is automated. The locks just broke.

The fablnx pipeline 04 — automated, end to end

The entire pipeline. Automated.

01

Drop the drawings

The contract PDF is the whole workflow. No setup, no export, no re-keying.

02

Read straight off the page

Members, grids and specs are parsed directly from the sheet — pixels become structured data.

03

The model builds itself

The full 3D model assembles natively in Tekla Structures — nothing rebuilt by hand.

04

Every joint, code-checked

Each connection is sized and checked to AISC 360 automatically — no hand calculations.

05

Delivered in any format

PDF, DWG, IFC, NC1 — whatever the client specifies, out the other end.

4–8 hours not 4–6 weeks · the same project
The result 05 — proof

The economics flip.

No one else goes end to end — drawings in, fabrication-ready model out.
