Hexagon SmartPlant 3D
Alternative: 2D Engineering Extraction, Not 3D Authoring
Hexagon SmartPlant 3D is the authoring backbone for greenfield 3D plant design within the Hexagon SmartPlant ecosystem: model new plants in 3D, generate isometrics, manage piping spec, run clash detection. It is not an extraction tool: SmartPlant 3D generates content; it does not read existing PDFs, scanned 2D drawings, or third-party content. Pathnovo extracts structured engineering data from 2D engineering documents (P&IDs, isometrics, datasheets, HAZOP, mill certs) to produce EPC deliverables. For greenfield 3D-native projects, SmartPlant 3D is the engineering backbone. For brownfield digitisation + 2D-source MTO + mid-EPC scope + non-Hexagon sources, Pathnovo extracts what SmartPlant 3D cannot.
Why Switch from Hexagon SmartPlant 3D
2D Extraction vs 3D Authoring
Hexagon SmartPlant 3D's strength is greenfield 3D plant design authoring. Pathnovo's strength is 2D extraction from existing PDFs and scanned engineering drawings. Different workflows entirely: SmartPlant 3D creates 3D content; Pathnovo reads 2D content. Most owner-operators end up using both: SmartPlant 3D for new design, Pathnovo for brownfield digitisation and non-Hexagon sources.
Piping MTO from Scanned Isometrics (Blue Ocean)
SmartPlant 3D generates piping MTO from the 3D plant model. For projects without a 3D model (brownfield revamps, mid-EPC scope, M&A integration, legacy plants), SmartPlant 3D does not apply. Pathnovo extracts piping MTO from scanned + PDF + hand-drawn isometric drawings, no 3D model required. See the piping MTO from isometric workflow.
Mid-EPC Accessibility
Hexagon SmartPlant 3D enterprise licensing is positioned for tier-1 EPC and large owner-operators (typically $200K-$1M+ multi-seat per project bundled within broader SmartPlant ecosystem contract). Pathnovo is credit-based; mid-EPC contractors can produce engineering deliverables without enterprise commitment. See pricing for plans.
Indian Regulatory Layer
SmartPlant 3D has no IBR, OISD 118, PESO, or CCOE compliance output. Pathnovo encodes all four regimes natively. See the indian EPC compliance bundle.
Services-Arm Population Story
For Hexagon-committed customers running SmartPlant 3D as the 3D authoring backbone, Pathnovo provides the upstream services-arm scope: extract structured data from existing 2D drawings, populate SmartPlant Foundation via SDx2, then SmartPlant 3D authors new design on top of the populated baseline.

Who Wins for Which Buyer
Real buyer scenarios with honest “who fits best” framing.
Tier-1 EPC contractor designing greenfield $500M+ capex project end-to-end inside Hexagon SmartPlant ecosystem
Winner: Hexagon SmartPlant 3DSmartPlant 3D's multi-discipline 3D plant authoring + clash detection + isometric generation is the right backbone for greenfield Hexagon-native projects. Pathnovo does not replace authoring tools; we extract from existing 2D drawings.
Brownfield digitisation with legacy PDF P&IDs and scanned isometrics (no 3D model exists)
Winner: PathnovoSmartPlant 3D cannot extract from existing 2D drawings. Pathnovo extracts from any PDF / scanned / hand-drawn isometric and feeds SmartPlant Foundation via SDx2. See the piping MTO from isometric workflow.
Mid-EPC contractor needing piping MTO from existing isometrics
Winner: PathnovoSmartPlant 3D's enterprise scope is not commercially viable at mid-EPC scale. Pathnovo's credit-based pricing with 48-hour first delivery makes piping MTO extraction accessible at mid-EPC scope without a 3D model.
Owner-operator brownfield revamp project extending existing 3D-modeled plant with new modules
Winner: Pathnovo + SmartPlant 3DHybrid pattern. SmartPlant 3D handles greenfield extension authoring; Pathnovo extracts structured data from existing 2D drawings of the brownfield baseline. Common pattern for refinery and petrochemical brownfield revamps.
Indian PSU refinery with IBR + OISD 118 + PESO + CCOE compliance obligations
Winner: PathnovoSmartPlant 3D has no Indian regulatory bundle. Pathnovo encodes all four regimes natively. See the indian EPC compliance bundle.
When the competitor is still the right choice
Honest framing matters. Here are the scenarios where Pathnovo is not the right fit.
- 01
SmartPlant 3D's multi-discipline 3D plant authoring + clash detection + isometric generation are outside Pathnovo's scope. For greenfield 3D plant design, SmartPlant 3D (or comparable: AVEVA E3D, Bentley OpenPlant) remains the platform.
- 02
SmartPlant 3D's tight integration with SmartPlant Foundation + Instrumentation + HxGN SDx2 is materially deeper than any third-party extraction layer for Hexagon-committed customers.
- 03
SmartPlant 3D's customer base on $500M+ capex projects (Aramco, ADNOC, Reliance Jamnagar, IOCL, BPCL, KBR, McDermott) demonstrates the platform-maturity Pathnovo does not replicate at the 3D authoring layer.
- 04
For organisations committed to the full Hexagon SmartPlant stack as the corporate engineering backbone, SmartPlant 3D's integrated 3D-to-SDx2 data flow is the natural cultural fit. Pathnovo bridges what SmartPlant ecosystem cannot ingest natively from non-Hexagon 2D sources.

Frequently Asked Questions
What is Hexagon SmartPlant 3D?
Hexagon Intergraph SmartPlant 3D (formerly Intergraph PDS 3D) is the global incumbent 3D plant design authoring suite within the Hexagon SmartPlant ecosystem. Used by tier-1 EPC contractors and large owner-operators on $500M+ capex projects worldwide for multi-discipline 3D plant design, clash detection, and isometric generation.
How does SmartPlant 3D compare to AVEVA E3D?
Both are tier-1 3D plant design authoring suites. AVEVA E3D dominates global EPC for greenfield projects within the AVEVA ecosystem; SmartPlant 3D has a stronger position in tier-1 owner-operator plants within the Hexagon SmartPlant ecosystem. Both share the same fundamental limitation: they generate 3D content but cannot extract from existing 2D drawings or non-ecosystem sources. Pathnovo bridges that gap for either ecosystem.
Can Pathnovo replace SmartPlant 3D?
No. SmartPlant 3D is an authoring tool; Pathnovo is a 2D extraction layer. They serve different points in the workflow. Most Hexagon-committed owner-operators end up using both: SmartPlant 3D for new design, Pathnovo for brownfield 2D extraction and non-SmartPlant sources.
Can Pathnovo extract piping MTO without a 3D model?
Yes. This is Pathnovo's blue-ocean workflow. Pathnovo extracts piping MTO from scanned + PDF + hand-drawn isometric drawings using 2D topology recognition. No 3D model required. For projects without a SmartPlant 3D-authored 3D model, this is the only path to piping MTO from existing drawings.
Can mid-EPC contractors afford SmartPlant 3D?
Realistically, no. SmartPlant 3D enterprise licensing is bundled within Hexagon SmartPlant ecosystem contracts (typically $200K-$1M+ multi-seat scope for greenfield EPC projects). Mid-EPC contractors ($50M-$500M project scope) cannot absorb the licence + implementation cost. Pathnovo's credit-based pricing makes engineering data delivery accessible at mid-EPC scale without enterprise 3D authoring commitment.
Can Pathnovo feed data into SmartPlant 3D?
Indirectly. SmartPlant 3D consumes structured design data primarily through SmartPlant Foundation. Pathnovo feeds extracted data into SmartPlant Foundation via the SDx2 data take-on schema. For brownfield digitisation projects feeding into greenfield SmartPlant 3D-authored design, Pathnovo provides the upstream extraction layer. See the Hexagon SDx integration for the technical detail.
