The only managed service globally that extracts piping material take-off from scanned, PDF, and hand-drawn isometric drawings. No 3D model required. No template configuration. 48-hour turnaround with 99.5% contractual accuracy. Built for brownfield EPC projects, revamps, and legacy plant digitisation where 3D-model-based tools like AVEVA ERM and Hexagon Smart Materials cannot operate.
Scanned hand-drawn isometrics, CAD PDF exports, AutoCAD DWG, ISOGEN outputs, and legacy drawings from the 1980s onward. Faded scans, rotation, handwritten annotations, and non-standard drawing conventions handled without pre-processing.
Pipe cut lengths per line number, every fitting (elbow, tee, reducer, cap), every flange with face rating and bolting, gaskets, studs and nuts, insulation lengths, supports, and field weld joints. Output maps directly to client's MR/BOM template.
Every MTO line validated against the project piping material class (PMS). Material grade, pressure class, schedule, end preparation, and fitting type cross-checked automatically. Specification break transitions flagged.
Cut-to-length pipe schedules, spool identification, field-vs-shop weld split, weld joint IDs, and isometric-level BOM rollup delivered in fabrication shop formats (PDS, PCF, IDF, Excel).
Drawings uploaded by 9am are returned as structured MTO within 48 hours with a contractual SLA. Volume pricing scales to 5,000+ isometric sheets per project.
AI extraction followed by piping engineer review. Published contractual accuracy of 99.5% on pipe lengths, fitting counts, and specification callouts. Independent audit trail provided per sheet.
Output format configurable to client's Piping Material Specification (PMS), Material Requisition (MR), or ERP purchase order schema (SAP MM, Oracle iProcurement, JDE). CSV / Excel / JSON / XML delivery.
Handle isometrics from revamp scope where some lines are new, some are existing, and some are being modified. Changed-line callouts and as-built deltas supported.
Brownfield refinery revamp: extract MTO from 800 legacy isometrics archived as scanned PDFs
Greenfield EPC without full 3D model: isometrics issued for construction need MTO for procurement
Fabrication shop pre-ordering: isometrics arrive on-site, MTO needed in 48 hours before material cut-off
Legacy plant digitisation: ONGC / IOCL / HPCL / BPCL scan-room drawings converted into structured asset registers
As-built MTO from field redline markups on issued-for-construction isometrics
MTO QA: validate incumbent EPC's manual MTO against the actual isometric for cost recovery
Insurance / valuation audits needing a current MTO against a plant's legacy drawing set
Change order MTO: Rev B isometric issued, delta MTO needed against Rev A for cost impact
AVEVA ERM and Hexagon Smart Materials extract MTO from 3D digital models (E3D / Smart 3D). For brownfield plants, revamps, and most Indian / Gulf mid-EPC projects, no 3D model exists. The isometric PDF or the scanned hand-drawing is the only source of truth. Pathnovo is the only vendor globally with a production managed service that solves this.
Scanned PDFs (any DPI from 150 up), native AutoCAD DWG / DXF, ISOGEN PCF / IDF outputs, PDS isometrics, hand-drawn legacy drawings scanned as TIFF or JPEG, and photographed drawings from mobile cameras. No pre-processing required. We handle skew, rotation, and stitched multi-page drawings.
Manual MTO by an experienced piping engineer runs 90–95% accuracy at a rate of 2–4 hours per isometric. Pathnovo delivers 99.5% contractual accuracy on pipe lengths, fitting counts, flange ratings, and material callouts, typically under 15 minutes per isometric once drawings are in queue. The difference at scale is enormous: on a 1,000-isometric project, a 5% manual error is thousands of incorrect line items affecting every downstream PO and shop ticket.
Any batch of isometrics uploaded before 9am is returned as structured MTO within 48 business hours. The SLA is contractual; penalty clauses apply. For ongoing projects we configure dedicated capacity so sustained daily volume is handled at a fixed delivery slot.
Yes. Revamp isometrics typically carry markup showing existing / demolish / new scope. Pathnovo tags each MTO line item to scope (existing, modified, new-installed, demolish) so procurement teams order only new material and fabrication teams know what is field-welded to existing pipework.
Output formats are configurable. We deliver in any format your downstream system needs: AVEVA E3D MTO tables, Hexagon Smart Materials BOM format, SAP MM purchase-requisition CSV, Oracle iProcurement JSON, JDE BOM schema, or raw Excel / CSV / XML. Custom formats are configured per client at no extra fee.
ASME B31.3 (process piping), ASME B31.1 (power piping), B31.4 / B31.8 (pipelines), EN 13480, PD 5500. Project-specific piping material classes (PMS) are loaded at project kick-off. The system validates every MTO line against the applicable PMS automatically.
IPS iDrawings handles P&IDs, not isometric MTO. PlantFCE does cost estimation on P&ID annotation. Neither extracts isometric MTO. Pathnovo is the only vendor with a production managed service for scanned-isometric piping MTO globally.
Credit-based: each isometric sheet consumes 8 credits. The full platform is included on every paid tier, so revision-set workflows draw from the same credit pool as P&ID extraction, MTO, and reconciliation. Starter (1,000 credits/month), Professional (5,000 credits), Scale (25,000+ credits), Enterprise custom for Indian PSU, Gulf EPC, and global O&G operators with dedicated capacity. Free 14-day trial available. See our pricing page for full plan details.
Yes. Pathnovo's MTO output is designed to feed directly into MR package assembly, which we also offer as a managed service. End-to-end workflow: scanned isometrics → MTO → MR package → BOM → PO-ready data, all delivered in the same 48-hour slot.

Pathnovo's computer-vision models read isometric drawing geometry to identify pipe runs, every fitting (elbow, tee, reducer, cap), every flange with face and rating, valves with tag, weld joints, and supports. Text and numeric annotations (pipe spec, dimensions, line number, material grade) are parsed alongside. The extracted graph is reconciled against the project's piping material class (PMS) to validate every line item. Output is a fully quantified MTO in client-native format. The end-to-end process runs in minutes per drawing, versus 2–4 hours manually.
99.5% contractual accuracy on pipe lengths, fitting counts, flange ratings, and material callouts. Manual MTO by senior piping engineers achieves 90–95%. On a 1,000-isometric revision set, that 5-percentage-point gap is thousands of incorrect line items affecting every downstream purchase order, every fabrication shop ticket, and every field measurement. Pathnovo's accuracy claim is backed by a per-sheet audit trail and a contractual SLA with penalty clauses.
Indian and Gulf EPC contractors working on refinery revamps, petrochemical plant expansions, fertiliser upgrades, LNG projects, and greenfield builds where a full 3D model is not feasible. Typical buyers: VP Engineering, Piping Lead, Materials Engineer, Procurement Manager. Named customers include McDermott, GCKC (in build), Zetwerk (in build). Target project size: $60M to $6B capex.
AVEVA ERM and Hexagon Smart Materials extract MTO from their own 3D models (AVEVA E3D, Hexagon Smart 3D); they cannot read any drawing that was not authored in the native tool. Pathnovo extracts from any isometric format (scanned, PDF, hand-drawn, third-party CAD) with no authoring tool dependency. For brownfield and mid-size EPC work (the bulk of Indian and Gulf projects), Pathnovo is the only option.
Yes. Our training set includes scanned hand-drawn isometrics from the 1980s onward, faded blueprints, photographed drawings, and isometrics with handwritten revision markups. Accuracy is slightly lower on very poor-quality scans (typically 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.
