Drawings uploaded by 9am IST returned as structured MTO within 48 business hours. Contractual SLA with penalty clauses. Volume pricing scales to 5,000+ isometric sheets per project with dedicated daily capacity.
Models trained on ISO 4067 isometric symbology and ISA 5.1 instrumentation conventions. Recognises every standard fitting, valve, flange, and instrumentation symbol with classification accuracy above 99%. Trained on 200,000+ isometric drawings spanning five decades.
Output formats configurable per client: SAP MM purchase requisition CSV, IBM Maximo asset import, AVEVA E3D MTO tables, Hexagon Smart Materials BOM format, Oracle iProcurement JSON, JDE BOM schema, or raw Excel/CSV/XML. Custom client-format mapping included at no extra fee.
Handle revamp isometrics where some lines are new, some are existing, some are being modified or demolished. Each MTO line tagged to scope (existing / modified / new-installed / demolish) so procurement orders only new material and fabrication knows what is field-welded to existing pipework.
Pipe cut lengths per line number, bore size, schedule, end preparation, material grade, and specification class extracted from isometric geometry and validated against project Piping Material Specification (PMS).
Every elbow, tee, reducer, cap, cross, plug, coupling, and valve extracted with type, size, rating, end preparation, material, and tag (where applicable). Specification break transitions flagged automatically.
Flange face type (RF, FF, RTJ), pressure class, material, gasket type and material, stud size and length, and nut grade extracted per ASME B16.5 / B16.47 / EN 1092 standards.
Every weld joint identified with joint ID, type (butt / socket / fillet / branch), field-vs-shop classification, and spool-level rollup. Cross-link to /solutions/piping-mto-extraction/weld-schedule for full weld schedule generation.
Line numbers parsed with full attribute set: fluid service, design temperature, design pressure, insulation class, painting code, and piping material class. Cross-sheet line continuations tracked across multi-sheet isometric sets.
Sheet-level MTO consolidated into project-level BOM by specification, size, material grade, and procurement category. Surplus and scrap estimates calculated per project standards.

No pre-processing required. The system handles skew, rotation, faded scans, and stitched multi-page drawings automatically.
48 hours per revision set under managed service. Drawings uploaded by 9am IST are returned as structured MTO within 48 business hours, contractually guaranteed. Individual drawings process in under 15 minutes once in queue. Sustained-volume projects (500+ sheets per day) run on dedicated capacity (Scale or Enterprise tier) with the same 48-hour SLA. The free 14-day trial completes its first delivery within 24 hours of upload.
AVEVA ERM, Hexagon Smart Materials, and Bentley OpenPlant Isometrics Manager all generate isometrics from a 3D model (AVEVA E3D, Hexagon Smart 3D, Bentley OpenPlant Modeler) and produce MTO from the model's metadata. None of them can read an isometric they did not author. For brownfield, revamp, and most mid-EPC projects in India and the Gulf, no 3D model exists. The isometric PDF or scanned hand-drawing is the only source of truth. Pathnovo is the only managed service globally that extracts MTO from non-modelled isometric drawings.
99.5% on pipe lengths, fitting counts, flange ratings, and material callouts, contractually backed with a remedy clause. Slightly lower on very poor-quality scans (typically 97-98% on faded blueprints, hand-photographed drawings). Every batch begins with a sample-review accuracy estimate before commercial commitment. A per-sheet audit trail is provided with every delivery so any out-of-spec line item is traceable to the source drawing region.
Credit-based, full platform included on every paid tier. Each isometric sheet consumes 8 credits. Starter (₹40,000/$1,200 per month, 1,000 credits) handles ~125 isometrics; Professional (₹1,75,000/$5,500, 5,000 credits) handles ~625; Scale (from ₹6,50,000/$20,000, 25,000 credits) handles ~3,125 sheets per month. Indian PSU rate-card compatibility available. Free 14-day trial with 100 credits before commitment. Full pricing detail at /pricing.
No. P&ID extraction reads piping & instrumentation diagrams (process flow, control loops, instrument tags). Isometric extraction reads isometric piping drawings (3D pipe geometry projected onto 2D, with bills of materials, weld joints, and field measurements). Pathnovo offers both as distinct services because the source documents, output formats, and downstream buyers are different. P&ID extraction → instrument index, equipment list, line list. Isometric extraction → piping MTO, BOM, weld map.
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.
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. See /solutions/procurement-intelligence for the procurement intelligence cluster.

Pathnovo's computer-vision models read isometric drawing geometry to identify pipe runs, every fitting (elbow, tee, reducer, cap), every flange with face type and pressure rating, valves with tag references, weld joints, and supports. Text and numeric annotations (pipe spec, dimensions, line number, material grade, service) 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 under 15 minutes per drawing once in queue, versus 2-4 hours manually. Trained on 200,000+ isometric drawings spanning five decades of drawing standards.
99.5% contractual accuracy on pipe lengths, fitting counts, flange ratings, and material callouts. Manual MTO by senior piping engineers achieves 90-95% at 2-4 hours per drawing. 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. Free 14-day trial with 100 credits before any project commitment.
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 (live: 10,247 tags, 600 P&IDs), 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 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. Pathnovo's output is also designed to feed AVEVA, Hexagon, or Bentley downstream, so customers can keep their authoring tool of choice while solving the legacy-drawing problem.
Excel S6 ranking #1 in unmet workflows in EPC document intelligence. Every brownfield project needs it. Every revamp needs it. Most mid-EPC greenfield projects in India and the Gulf need it because full 3D modelling is not commercially viable for sub-$500M capex projects. The cost of manual isometric MTO at scale is staggering: 15,000 isometric drawings × 3 hours per drawing × ₹3,000/hour senior piping engineer rate = ₹13.5 crore per project. Pathnovo's credit-based tier model recovers 80-95% of that cost, with higher accuracy and 48-hour turnaround instead of 8-12 weeks.
