For WebPano users, understanding these distinctions is crucial – it allows for efficient planning of presentations, measurements, and design processes. This article explains what point clouds, meshes, and CAD/BIM models are, their advantages, disadvantages, costs, and when to use them.

1. Point Cloud – the most accurate representation of reality

A point cloud is generated directly from 3D scanning (laser or photogrammetry) and looks like millions of colored dots in space, each with precise coordinates (x, y, z).

Applications:

• precise measurements and analysis,

• quality control (comparing the real object to CAD/BIM design),

• documentation of the existing state.

Advantages and disadvantages:

• maximum accuracy and a reliable representation of reality,

• harder to interpret for inexperienced users, “raw” appearance.

Cost and processing:

• Generating a point cloud is a direct result of scanning and costs no more than fieldwork.

• No post-processing is required, only decimation (automatic process).

• Data must be cleaned (e.g., removing noise or unnecessary elements), affecting preparation time and cost.

2. Mesh – surfaces instead of dots

A mesh is created from a point cloud by connecting points into triangles forming surfaces. This makes the object visually readable and suitable for 3D presentations.

Applications:

• attractive visualization for clients,

• collision checking (full as-built model not always required).

Accuracy and optimization:

• More scanner positions result in a denser mesh with fewer “holes,”

• Quality depends on triangle optimization – the mesh can be simplified for smooth performance or retain details at the cost of larger file size,

• Mesh is non-editable – it is a representation of reality, not a design model.

Advantages and disadvantages:

• readable and intuitive,

• sufficient for many visualization and collision-checking applications,

• less accurate than the raw point cloud,

• cannot be modified like CAD/BIM models.

Cost:

• medium – requires additional processing; higher precision and more scans increase preparation costs.

• Process is still automated, time-consuming but computationally feasible.

3. CAD / As-Built / BIM Models – full functionality

CAD Model:

• Created in design software (AutoCAD, MicroStation, Revit, ArchiCAD).

• Contains mathematically defined geometry – objects are editable and compatible with multiple CAD programs.

• Applications: design, technical documentation.

BIM Model:

• A 3D model of a building enriched with information on materials, costs, and construction time.

• Applications: multidisciplinary coordination, construction planning, facility management.

As-Built:

• Reflects the actual state of the object after construction.

• Editable and updatable – unlike a mesh.

Hybrid Approach – cost vs. accuracy compromise:
Fully modeling an object can be expensive and time-consuming. A hybrid approach uses a mesh for the whole object and CAD modeling only for critical fragments.

Examples:

1. Industrial installation – model only connection points with new installations.

2. Steel structure – hall remains a mesh; CAD models only joints for new elements.

3. Building – mesh for the whole structure + precise window/door openings for facade or joinery alignment.

This approach reduces costs and time while maintaining high accuracy where it matters most.

4. Costs and practical decisions

Format	Cost	Accuracy	Application	Editability
Point Cloud	low	very high	measurements, quality control, documentation
Mesh	medium	medium–high	visualization, collision checking, online presentations
CAD/BIM Model	high	high, ideal	design, analysis, facility management
Hybrid (mesh + CAD fragments)	medium–high	where needed	cost savings, precision only in key areas	partial

Summary

• Point Cloud = most accurate representation of reality.

• Mesh = readable, great for visualization and collisions, but non-editable.

• CAD/BIM/As-Built Model = full functionality, editable, expensive but indispensable for design and management.

• Hybrid = compromise: mesh for the whole object + CAD only where truly necessary.

Condition Monitoring Location point cloud

Do you manage critical Condition Monitoring Locations (CMLs) on your industrial assets in line with API inspection standards? Are you looking for a way to monitor pipeline integrity, prevent corrosion, and plan retrofits more effectively—including estimating the time and cost of scaffold installations? Your answer might be WebPano Visual Plant from 3Deling.

Visual Plant platforms like WebPano are redefining how CML management and pipeline modernization planning are done. Whether you’re working with a full 3D model or only point cloud data, WebPano allows you to locate, annotate, edit, and manage these crucial inspection points while staying fully compliant with industry codes.

What Are CMLs in API Standards?

CMLs (Condition Monitoring Locations) are strategically selected points on industrial systems—especially piping (API 570) and pressure vessels (API 510)—designated for regular monitoring. These locations are used to assess material loss due to corrosion (uniform, localized, or under insulation/CUI), erosion, wear, or other forms of degradation.

Ultrasonic thickness readings are often taken at CMLs during inspections. API 570 and API 510 recommend tracking the lowest or average readings from these points to calculate corrosion rates and remaining life. Accurate spatial placement of these locations is critical for mechanical integrity, failure prevention, and long-term maintenance planning—especially within Risk-Based Inspection (RBI) frameworks based on API RP 580.

Two Scenarios: Managing CMLs with and without a 3D Model

Scenario 1: CML Management with a 3D Model

• Object Search & Navigation: Easily locate CML points via the search function in the LISTS panel.
• Pinpoint Accuracy: The target icon helps pinpoint specific CMLs directly on the 3D model in the viewport.
• Visibility: CML markers are clearly visible on the model, facilitating rapid inspection planning.
• Real-Time Measurement: Use the measurement tool to check distances, access routes, or clearance.
• Import Custom Geometry: Upload your own .obj files—such as scaffolding models—to simulate real-world interventions.
• Adjust for Reality: Move and rotate imported objects to test for fit within tight spaces.
• Editable Interface: Add, organize, and edit CML points through an intuitive browser-based interface.

Scenario 2: CML Management Using Only Point Cloud Data
