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.
Auto-generate complete weld schedules, NDE (non-destructive examination) plans, and PWHT (post-weld heat treatment) requirements directly from isometric drawing data. Every weld joint identified by joint ID, classified by type (butt / socket / fillet / threaded), sized, matched to material combination, assigned to the correct WPS (welding procedure specification), and tagged with NDE method and percentage. ASME B31.1 / B31.3 / B31.4 / B31.8, EN 13480, and ASME Section IX compliant. Works on any isometric format (scanned PDF, CAD export, ISOGEN, PDS) with no 3D model required.
Yes. Pathnovo is the only product that extracts piping MTO from scanned hand-drawn isometric drawings. Our models handle faded scans, hand-annotated markups, and non-standard conventions from any era.
Pipe lengths, fitting types and counts, flange specifications, fastener requirements, weld joint types, material grades, specification breaks, insulation requirements, and support locations.
Manual MTO from isometrics takes 2-4 hours per drawing with 90-95% accuracy. Pathnovo processes drawings in minutes with 99.5% accuracy and automated reconciliation against piping specifications.
Yes. Weld schedules include joint ID, joint type, pipe size, material grade, WPS assignment, NDE requirement (RT, UT, MT, PT), PWHT specification, and welder qualification requirements.
Upload the PDF (scanned, native, or DWG-converted). Pathnovo's computer-vision models read the isometric geometry and annotations, extract every pipe segment, fitting, flange, valve, and weld joint, validate against your piping material class (PMS), and return a fully quantified MTO in your client format. Typical turnaround is 48 hours per revision set with a 99.5% contractual SLA.
AVEVA ERM, Hexagon Smart Materials, and Bentley OpenPlant Isometrics Manager all generate isometrics from a 3D model (E3D, Smart 3D, 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. Pathnovo is the only managed service globally that solves this.
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). Every batch begins with a sample-review accuracy estimate before commercial commitment, and a per-sheet audit trail is provided with every delivery.
Credit-based, with the full platform included on every paid tier. Each isometric sheet consumes 8 credits, so a 1,000-sheet revision set is 8,000 credits, sitting comfortably inside Professional (5,000 credits/month) or Scale (25,000 credits/month) depending on tempo. Starter (1,000 credits/month) is sized for smaller batches. Free 14-day trial with 100 credits before any commitment. See our pricing page for full plan details.

Pathnovo's models read isometric geometry to identify pipe runs, fittings, flanges, valves, and weld joints. The system parses dimensions, specification callouts, and material annotations to generate complete MTOs. Unlike 3D model extraction, this works on legacy 2D isometrics including hand-drawn drawings from the 1980s.
Pathnovo delivers 99.5% accuracy on piping MTO extraction with a contractual SLA. Manual MTO compilation by experienced piping engineers achieves 90-95% accuracy. The difference is significant at scale, for 10,000 isometrics, 5% error means thousands of incorrect line items affecting procurement, fabrication, and cost control.
