Industrial Fabrication Takeoff Software (AI-Powered)
One AI platform for the fabrication shop: structural steel, sheet metal and ductwork. Turn drawings and 3D models into quantities, tonnage and fabrication BOMs — beams and connections, laser-cut blanks and gauge, duct footage and SMACNA weight.
Industrial fabrication takeoff software uses AI to read the drawings and 3D models a fabrication shop works from — structural steel plans, shop drawings, 3D CAD parts and mechanical plans — and automatically extract the quantities needed to cut, form and price the work: member counts and steel tonnage, sheet-metal gauge and flat-pattern blanks, and duct footage with SMACNA weight. It turns hours of measuring the drawing or the model by hand into a review pass, where every quantity traces back to the mark, sheet or part it came from.
Three fabrication trades, one platform
Steel, sheet metal and ductwork share the same problem — turning a drawing or a model into a priced cut list. Each has a dedicated reader.
Structural Steel Takeoff →
Framing plans, structural schedules, shop drawings and reinforcement details → beams, columns, joists, deck, connections and rebar, with marks reconciled across sheets and tonnage from the stated sections.
Sheet Metal Takeoff (STEP → BOM) →
Drop a 3D CAD part — STEP, STL or OBJ — and get a fabrication BOM: material, sheet gauge, flat-pattern blank size and cut weight, per part and across the assembly. Try the free demo on a real part.
HVAC Duct Takeoff →
Mechanical plan sets → duct linear footage by size and system, fitting and diffuser counts, and SMACNA sheet-metal weight by the pound — a duct BOM in minutes instead of a day of tracing.
How AI Fabrication Takeoff Works
Four steps from a drawing or a 3D part to a priced fabrication BOM with tonnage and weight.
Upload drawings or 3D parts
Bring what the shop actually receives: PDF structural and mechanical plan sets, shop drawings and schedules, or 3D CAD parts (STEP, IGES, STL, OBJ). Aginera reads every sheet and every solid — no manual page setup.
AI reads the fabrication scope
Structural drawings yield beams, columns, joists, deck and connections; 3D parts yield material, gauge and flat-pattern blank; mechanical plans yield duct runs, fittings and terminals. Each drawing type is read with a schema written for it, not a generic reader.
Quantities become tonnage and BOM
Sections resolve to steel tonnage; solid volume and gauge resolve to sheet-metal weight and blank area; duct sizes resolve to SMACNA sheet-metal weight. Marks are reconciled across sheets and identical parts collapse to a quantity.
Review, price and export
Every line carries a confidence score and a reference back to the mark, sheet or part it came from, so review is a targeted spot-check. Export the fabrication BOM to Excel or into your estimating workflow.
Exact where the geometry is exact, honest where it isn't
Weight taken from a 3D solid is not an estimate — the CAD kernel computes true volume and multiplies by material density, so a sheet-metal or machined part's weight is accurate to the model. That determinism is why fabrication takeoff from 3D is a genuinely different proposition from tracing a 2D plan.
Quantities read from 2D drawings are a fast first pass a fabricator verifies: schedules and tables extract most reliably, framing plans and dense mechanical sheets are harder, scanned sets hardest. Every line carries a confidence score and a source reference so review effort goes exactly where it is needed — and we'd treat any vendor quoting one accuracy number across all drawing types, ourselves included, with caution.
Industrial Fabrication Takeoff — Frequently Asked Questions
What is industrial fabrication takeoff software?
Industrial fabrication takeoff software uses AI to read the drawings and 3D models a fabrication shop works from — structural steel plans, shop drawings, 3D CAD parts and mechanical (HVAC) plans — and automatically extract the quantities needed to cut, form and price the work: member counts and steel tonnage, sheet-metal gauge and flat-pattern blanks, and duct footage with SMACNA weight. Instead of measuring the drawing or the model by hand, the estimator reviews AI-generated quantities that trace back to the source.
Which fabrication trades does Aginera cover?
Three that share the same fabrication DNA: structural steel (framing plans, schedules, shop drawings, connections and rebar), sheet-metal and machined parts (STEP/STL/OBJ 3D models → material, gauge, blank size and weight), and HVAC ductwork (mechanical plans → duct linear footage, fittings, terminals and SMACNA sheet-metal weight). Each has a dedicated page and a dedicated extraction schema.
Can it produce steel tonnage and sheet-metal weight for pricing?
Yes. Where a structural drawing states the section (a W12x26, an HSS size, a rebar diameter) the quantity is expressed in weight as well as count and length. For 3D sheet-metal parts, weight is exact geometry — the CAD kernel computes true solid volume and multiplies by material density. For ductwork, sheet-metal weight is derived from duct size and gauge using SMACNA conventions. Where a section is missing on the sheet, Aginera reports the count and flags it rather than assuming and producing a confident wrong tonnage.
What file formats does it read?
PDF plan sets and shop drawings, CAD files (DWG, DXF), and neutral 3D formats — STEP (.step/.stp), IGES (.iges/.igs), STL and OBJ — parsed with an OpenCascade CAD kernel. Steel and duct scope comes from the 2D drawings; sheet-metal and machined-part scope comes from the 3D models.
How accurate is AI fabrication takeoff?
It varies by source, and pretending otherwise would be dishonest. Geometry taken from a 3D solid — volume, surface area, weight — is computed deterministically and is accurate to the model. Quantities read from 2D drawings depend on sheet type: schedules and tables extract most reliably, framing plans and dense mechanical sheets are harder, scanned sets hardest. Every line carries a confidence score and a source reference so verification is a targeted spot-check, and we treat any single accuracy figure quoted across all drawing types — including our own — with caution.
Who is this built for?
Steel fabricators and detailers, sheet-metal and machine shops quoting from customer CAD, and HVAC/mechanical contractors pricing ductwork — anyone who receives a drawing or a model and has to turn it into a cut list, a tonnage figure, or a fabrication BOM before they can quote.
