FablnxThe AI copilot for structural steel

Upload a contract drawing. Let the copilot find the steel. Trace it into a coordinated 3D model with a full material takeoff — all in one workspace.

📄

Read any drawing set

Drop in a contract PDF and the copilot reads every sheet — scanned images or native vector drawings — and sorts the steel structural pages from the noise.

🤖

An AI copilot that does the grunt work

Six agents identify sheets, extract the design spec, and detect grids, columns and beams so you review instead of retype.

Trace the model on the drawing

A precise 2D editor lets you place grids, dimensions, columns, beams and braces right over the drawing, with snapping and progressive unlock.

A coordinated 3D model

Commit your traced facts into one coordinated model you can orbit, section, measure and color — the way a detailer expects.

Design spec, extracted for you

The general notes are read into a clean AISC design spec panel — grades, bolts, welds and defaults, without hunting through pages.

RFIs that point at the problem

Validation surfaces conflicts and missing information as tracked RFIs, each of which jumps you straight to the spot on the drawing.

Material takeoff in a click

Every member rolls up into an advanced bill of materials — mark, quantity, profile, grade, length and weight — exportable to CSV.

Built like an IDE

Tabs, split views, a command palette and keyboard shortcuts throughout — a workspace that gets out of your way.
