Service Overview

Conversion of Point Cloud to 3D Modeling Services

Brownfield projects depend on accurate as-built information, and existing drawings rarely reflect what is installed. We convert registered laser-scan point clouds into intelligent, specification-driven 3D models — not just surfaces — so that the existing plant can be used directly in design, clash checking and deliverable extraction.

The as-built model becomes the baseline for revamps, tie-ins, debottlenecking projects, maintenance planning and digital-twin initiatives.

Scan Processing

Clean, registered point clouds

Scan data is checked, cleaned and prepared for modelling, and the modelling tolerance and level of detail are agreed with you before production starts.

  • Import of registered scans (E57, RCP / RCS, PTS, LAS and native formats)
  • Registration quality check and control point verification
  • Noise removal, segmentation and area-wise packaging
  • Modelling tolerance and level-of-detail (LOD) matrix agreed up-front
Intelligent Modelling

Specification-driven 3D objects

Components are modelled as intelligent objects in the target platform, carrying line numbers, specifications and tags.

  • Piping with line numbers, sizes, specs, valves and in-line items
  • Equipment with nozzles, platforms and ladders
  • Structural steel, concrete, cable trays and HVAC ducts
  • Modelling in AVEVA E3D, SmartPlant 3D or AutoCAD Plant 3D
  • Model-to-cloud deviation checks and QA reports
Brownfield Deliverables

Design that fits the existing plant

The as-built model is used for new design and for extracting up-to-date documentation.

  • Tie-in identification, tie-in isometrics and demolition drawings
  • Clash detection of new design against the scanned plant
  • As-built piping isometrics, GA drawings and P&ID verification
  • Model export to Navisworks / review platforms and asset information systems
FAQ

Frequently asked questions

What point cloud formats do you accept?

Registered scans in E57, RCP / RCS (Autodesk ReCap), PTS, LAS and most native scanner formats. Send a sample and we will confirm compatibility.

What modelling accuracy can you achieve?

Accuracy depends on scan quality and registration. We agree a modelling tolerance (typically in the range of ±10–25 mm for piping) and verify it with model-to-cloud deviation checks.

Do you model intelligent objects or just geometry?

Intelligent objects in the target plant design platform, with specifications, sizes, line numbers and tags, so the model can be used directly for design and isometrics.

Do you carry out the laser scanning?

We focus on processing and modelling. We can work with your existing scans or coordinate with a scanning partner.

Can the model be delivered in our software?

Yes — AVEVA E3D / PDMS, SmartPlant 3D, AutoCAD Plant 3D, or neutral formats for review platforms.
