Piping Fabrication Shop
Software, Iso to BOM
AI-powered MTO extraction from isometric drawings for piping fabrication shops. Cutting lists, weld schedules, and material requisitions, from legacy isometrics in minutes, not hours.
Problems We Solve
MTOs are compiled manually from isometrics
Fabrication shops receive hundreds of isometric drawings per project. Estimators spend days extracting pipe lengths, fittings, and weld counts manually, with 5-10% error rates that affect procurement and scheduling.
Cutting lists take hours per isometric
Converting isometric data into cut-to-length pipe schedules requires manual measurement of every pipe run, every bevel, and every fit-up gap.
Weld schedules are built from scratch for every project
Every weld joint needs WPS assignment, NDE method selection, and PWHT flagging based on material grade and thickness, manually repeated for every isometric.
Material procurement is based on estimates, not data
Without accurate MTOs, fabrication shops over-order by 15-25% to avoid shortages. The excess becomes scrap or slow-moving inventory.
Use Cases for Fab Shops

Create cutting lists for pipe spool fabrication automatically
Build weld schedules with WPS assignments and NDE requirements
Reconcile material requisitions against piping specifications
Reduce material procurement waste by 15-25%
Track fabrication progress against isometric deliverables
Documents We Process
Isometric Drawings
Legacy hand-drawn and CAD isometric drawings processed. Pipe runs, fittings, flanges, and weld joints extracted.
Cutting Lists
Cut-to-length pipe schedules with bevel specifications, fit-up gaps, and material grades.
Weld Schedules
Weld joint registers with type, size, WPS assignment, NDE requirements, and PWHT specs.
Material Requisitions
Consolidated material requirements by specification, size, and material grade.
Why do piping fabrication shops need automated MTO extraction?
Piping fabrication shops routinely receive hundreds of isometric drawings per project and must generate cutting lists, weld schedules, material requisitions, and spool drawings within tight fabrication deadlines. Each drawing requires manual extraction of pipe lengths, fittings, flanges, weld joints, and material grades; manual MTO takes 2-4 hours per isometric with 5-10% error rate. At scale, this means days-to-weeks of senior estimator time, 15-25% material over-ordering to avoid shortages (becoming scrap or slow-moving inventory), and fabrication schedule slippage. Pathnovo automates the entire extraction to minutes per isometric with contractual 99.5% accuracy, turning a schedule-critical activity into a non-critical 48-hour deliverable.
What makes piping fabrication shop software different from EPC MTO tools?
EPC-scale MTO tools (AVEVA ERM, Hexagon Smart Materials) extract from 3D models; they cannot read 2D isometric drawings. Fabrication shops work primarily from 2D isometric drawings issued by their EPC client (often hand-drawn or printed from legacy systems) without any access to the 3D model. Pathnovo is the only product globally that reads existing 2D isometrics to generate MTOs, cutting lists, and weld schedules for fabrication use. This blue-ocean workflow has zero direct competitors; see the [MTO from isometric workflow](/solutions/piping-mto-extraction/mto-from-isometric) for the capability detail.

Frequently Asked Questions
Can you process legacy hand-drawn isometric drawings?
Yes. Pathnovo is the only product globally that extracts piping MTO from scanned hand-drawn isometrics. Our training set includes scanned hand-drawn drawings from the 1980s onward, faded blueprints, photographed drawings, and isometrics with handwritten revision markups. Accuracy is slightly lower on very poor-quality scans (97-98% vs 99.5% on clean PDFs), but even low-quality scans are processable. We provide accuracy estimates per batch at sample review before committing to a project SLA.
What data is extracted from isometrics?
Complete fabrication data: pipe cut lengths per line number, every fitting (elbow, tee, reducer, cap, cross, bend), every flange with face rating and bolting, gaskets, studs and nuts, insulation lengths, supports, field weld joints with joint ID, shop weld joints, branch connections, specification breaks, material grades, pressure classes, schedules, and end preparations. Output maps directly to client's cutting list / BOM / weld schedule template.
How does this help fabrication shops?
Five concrete benefits: (1) MTO generation time compressed from 2-4 hours to under 15 minutes per isometric; (2) accuracy improved from manual 90-95% to contractual 99.5%; (3) material over-ordering waste reduced from 15-25% to under 3%; (4) cutting list and weld schedule generated same-day from isometric arrival; (5) weld joint register with WPS / welder qualification matrix ready for fabrication day one. For a typical shop loading 1,000+ isometrics per year, annual savings run $60,000 to $240,000 in estimator time and material waste combined.
Do you serve fabrication shops in Gujarat?
Yes. Active coverage across the Surat-Mumbai-Vadodara fabrication corridor, plus Dahej, Hazira, and Ahmedabad plants. Credit-based pricing in INR with GSTIN invoicing by Pathnovo India Pvt Ltd, full platform included on every paid tier, accessible for fabrication shops of all sizes including MSME-scale operations. See the Ahmedabad regional page for Gujarat market detail.
Does Pathnovo integrate with fabrication shop ERPs?
Yes. Direct export to fabrication shop ERP and planning systems: Larsen & Toubro LFMS, Intergraph SmartPipe, Bentley AutoPIPE, L&T Fabcon, Siemens Teamcenter (where used for piping fab), custom shop ERPs. Output formats include PCF (Piping Component File), IDF (Isometric Drawing File), ISOGEN-compatible XML, and standard Excel / CSV / JSON. Custom formats configured per client at no extra fee.
How does Pathnovo support IBR-scoped piping fabrication?
IBR-scoped piping (pressure piping for boilers and process equipment above IBR thresholds) requires IBR-approved welding procedures (WPS), IBR-certified welders, IBR-approved NDE, and IBR Chief Inspector stamping. Pathnovo's weld schedule output tags IBR-scoped welds specifically, assigns only IBR-approved WPS, validates welder qualification (IBR Form VIII acceptance), and maintains the traceability chain for Chief Inspector review. See the IBR compliance workflow for the full pipeline.
