Bentley OpenPlant
Alternative: Extract from Any Format, Not Just Bentley-Authored
Bentley OpenPlant is built for projects authored end-to-end inside the Bentley ecosystem. For brownfield plants, revamps, and the majority of Indian / Gulf mid-EPC projects where designs live in PDF form, OpenPlant's authoring workflow does not apply. Pathnovo extracts engineering data from any P&ID, isometric, or datasheet format (scanned, PDF, legacy CAD), without ecosystem lock-in. Feeds Bentley iTwin cleanly when iTwin is the downstream platform, works standalone otherwise.
Why Switch from Bentley OpenPlant
Works on Any Drawing Format
OpenPlant is authoring-native: designs are drawn inside the tool. Pathnovo reads any drawing format: scanned PDFs from the 1980s, AutoCAD legacy DWGs, third-party CAD exports, hand-annotated drawings. No authoring tool dependency.
No Instrumentation Module Gap
OpenPlant focuses on P&ID and isometric authoring. Full instrumentation module (instrument index, I/O list, loop diagrams) is not native. Pathnovo provides complete instrumentation coverage: see the instrument index automation workflow.
No Procurement or Compliance Layer
OpenPlant handles engineering design. It does not cover procurement (MR assembly, BOM generation, PO reconciliation, mill certificate traceability) or Indian regulatory compliance (IBR, OISD 118, PESO, CCOE). Pathnovo provides the full EPC delivery chain.
Mid-EPC Pricing
Bentley licensing starts around $5,995/yr per Piping Passport plus project-scale enterprise deals. Pathnovo is credit-based, full platform included on every paid tier, with a free 14-day trial: mid-EPC accessible. See pricing for plans.

Pricing Compared
Transparent pricing for every vendor where public. Where the vendor does not publish pricing, we say so.
Pathnovo
Credit-based subscription, full platform on every paid tier (P&ID + isometric + instrument + procurement + compliance), 14-day free trial with 100 credits and no card. Published per pricing page. Mid-EPC accessible at sub-six-figure annual spend; enterprise tier available for tier-1 EPC and owner-operator portfolio rollouts.
Bentley OpenPlant
OpenPlant Piping Passport starts around $5,995/yr per seat (Bentley public Subscription Store), but real-world plant deployments require additional modules (Modeler, Isometrics Manager, ProjectWise, iTwin Active Program) layered into enterprise contracts. Six-figure annual spend is typical for tier-1 EPC and owner-operator scope; not published. ProjectWise + iTwin licensing negotiated separately.
Who Wins for Which Buyer
Real buyer scenarios with honest “who fits best” framing.
Greenfield refinery designed end-to-end inside Bentley iTwin + ProjectWise ecosystem
Winner: Bentley OpenPlantAuthoring-native architecture wins when every drawing originates inside Bentley. Pathnovo's extraction value is minimal here; OpenPlant + iTwin is the right stack. Pathnovo can still be useful downstream for mill cert traceability and HAZOP register extraction that OpenPlant does not cover.
Brownfield refinery digitisation with 30 years of PDF P&IDs and scanned isometrics
Winner: PathnovoOpenPlant cannot extract from legacy formats. Pathnovo reads any PDF, scanned, or AutoCAD legacy drawing and outputs structured data in iTwin-compatible schema. Pair Pathnovo extraction with optional iTwin downstream for digital-twin operational use, per the digital twin data integration workflow.
Indian PSU refinery with IBR + OISD 118 + PESO + CCOE compliance obligations
Winner: PathnovoOpenPlant has no Indian regulatory bundle. Pathnovo encodes all four regimes natively; see the indian EPC compliance bundle. For Indian PSU procurement empanelment + rate-card pricing, Pathnovo is the only path.
Mid-EPC contractor ($50M-$500M project scope) building piping MTO from isometric drawings
Winner: PathnovoBentley OpenPlant licensing is positioned for tier-1 EPC and large owner-operators. Mid-EPC scope cannot absorb six-figure annual OpenPlant spend. Pathnovo's credit-based pricing with full platform on every paid tier makes piping MTO extraction commercially viable at mid-EPC scale.
Owner-operator portfolio with mixed Bentley + AVEVA + Hexagon authored plants
Winner: PathnovoOpenPlant reads only Bentley-authored content. Pathnovo extracts uniformly across all three ecosystems into one consolidated asset register, then feeds AVEVA AIM, Hexagon HxGN SDx2, or Bentley iTwin downstream depending on operator preference.
When the competitor is still the right choice
Honest framing matters. Here are the scenarios where Pathnovo is not the right fit.
- 01
If you are designing a greenfield plant inside the Bentley iTwin + ProjectWise stack from day one, Bentley OpenPlant's authoring-native architecture is the right engineering backbone. Pathnovo does not replace authoring tools; we extract from existing drawings.
- 02
Bentley's iTwin Active Program and ProjectWise AI-driven document search (GA 2026) are stronger choices for operators committed to Bentley as the long-term digital twin platform. Pathnovo integrates with iTwin but is not Bentley-native.
- 03
For organisations with significant existing Bentley investment + ML engineering team expecting Bentley-led delivery, OpenPlant + ProjectWise + iTwin is the obvious ecosystem fit. Pathnovo's productised extraction model adds value primarily for legacy drawing digitisation, not for greenfield Bentley-authored projects.
Frequently Asked Questions
Is Bentley OpenPlant the same as AVEVA or Hexagon SmartPlant?
Similar category (plant engineering authoring suite), different ecosystem. Bentley OpenPlant is native to the Bentley iTwin / ProjectWise ecosystem and integrates with Bentley's broader infrastructure portfolio (roads, rail, utilities). AVEVA and Hexagon each have their own authoring-tool ecosystems. For brownfield plants and mid-EPC projects outside any of these ecosystems, Pathnovo is the extraction engine that works standalone.
Can Pathnovo feed data into Bentley iTwin?
Yes. Pathnovo exports CFIHOS-compliant and iTwin-compatible structured data for ingestion into Bentley iTwin instances. Extract from legacy PDF drawings, feed iTwin for digital twin operational use. See the digital twin data integration workflow.
Does OpenPlant cover procurement and compliance?
No. OpenPlant is an engineering authoring suite. It does not cover material requisition assembly, BOM generation from drawings, technical bid evaluation, mill certificate traceability, or Indian regulatory compliance (IBR, OISD 118, PESO, CCOE). Pathnovo provides the full procurement intelligence and compliance layer on top. See the procurement intelligence pillar.
Can I use Pathnovo and Bentley OpenPlant together?
Yes, for operators with mixed portfolios: some projects authored in OpenPlant, others as PDF-based brownfield or mid-EPC. Pathnovo provides a uniform extraction layer across both, with OpenPlant-compatible output formats for projects that ultimately flow into iTwin or ProjectWise.
Which should I choose for a brownfield refinery digitisation?
Pathnovo, every time. OpenPlant is an authoring tool: it does not extract from legacy drawings. Brownfield digitisation requires reading existing paper / PDF archives, which Pathnovo does natively. Once extracted, the structured data can optionally be loaded into Bentley iTwin for operational digital twin use.
