From 3D Laser Scanning to SolidWorks

From 3D Laser Scanning to SolidWorks: Scan to BIM and Mechanical Engineering Consulting

Modern engineering projects often begin with an existing building, machine, process plant or industrial structure that has incomplete, outdated or unavailable drawings.

Traditional site measurement can provide basic dimensions, but it may not capture the full geometry, spatial relationships or installation constraints needed for accurate engineering design. This is where 3D laser scanning, Scan to BIM and SolidWorks-based mechanical engineering can form a complete digital engineering workflow.

Hamilton By Design provides engineering-led reality capture and mechanical design services for brownfield industrial, manufacturing, mining and infrastructure projects across Australia.



3D Laser Scanning Melbourne

3D laser scanning Melbourne provides a practical way to capture the existing condition of machinery, pipework, structures, buildings and industrial facilities.

A terrestrial laser scanner records millions of measurement points from multiple positions around the site. These individual scans are registered together to create a coordinated 3D point cloud representing the visible surfaces of the existing environment.

The point cloud can capture:

  • Structural steel and support frames

  • Mechanical equipment

  • Pipework and ducting

  • Platforms, stairs and access systems

  • Tanks, chutes and hoppers

  • Building interiors and service areas

  • Existing fabrication and installation constraints

  • Interfaces between new and existing equipment

For Melbourne engineering and industrial projects, laser scanning can reduce the need for repeated manual measurement and provide designers with a more complete understanding of the site before detailed design begins.

This is particularly useful for brownfield projects where new equipment must fit around existing structures, services and operating plant.

Turning Point-Cloud Data into SolidWorks Models

The point cloud created during scanning can be imported into compatible reality-capture, CAD and modelling software.

Relevant geometry can then be recreated as SolidWorks parts, assemblies or reference models. The amount of modelling detail depends on the project requirements.

For example, a project may require:

  • A simplified spatial model for equipment positioning

  • A detailed mechanical assembly

  • A fabrication-ready replacement component

  • A pipe-routing reference model

  • A structural interface model

  • A machine envelope for clearance checking

  • A layout for maintenance-access assessment

The point cloud does not automatically become a complete engineering model. Engineering judgement is required to determine which surfaces, features, interfaces and dimensions must be modelled accurately.

For mechanical projects, SolidWorks can then be used to develop design concepts, assemblies, fabrication drawings, bills of materials and engineering documentation.

Scan to BIM Services

Scan to BIM services convert measured site information into coordinated digital models that can be used for design, documentation and asset management.

Although BIM is often associated with architectural buildings, Scan to BIM can also support industrial and mechanical engineering projects.

A Scan to BIM workflow may include:

  1. Planning the areas and assets to be captured.

  2. Completing terrestrial LiDAR scanning on site.

  3. Registering and checking the scan data.

  4. Creating a coordinated point cloud.

  5. Modelling the required structures, equipment and services.

  6. Reviewing the model against the original scan.

  7. Issuing the required BIM, CAD or engineering deliverables.

Depending on the project, the final deliverables may include:

  • Revit models

  • Navisworks coordination models

  • AutoCAD drawings

  • SolidWorks models

  • STEP or SAT files

  • RCP or RCS point clouds

  • E57 or LAS scan data

  • General arrangements

  • Sections and elevations

  • Equipment and structural layouts

Scan to BIM is valuable when multiple disciplines need to work from the same existing-site information.

Architectural, structural, mechanical, piping and electrical teams can use a coordinated digital model to identify interfaces before construction or fabrication begins.

How SolidWorks Fits into a Scan to BIM Project

SolidWorks may not be the primary BIM authoring platform, but it plays an important role when a Scan to BIM project includes machinery, fabricated equipment or mechanical systems.

A BIM model may define the wider building or facility environment, while SolidWorks is used to design detailed mechanical components within that environment.

Examples include:

  • Equipment support frames

  • Access platforms and guarding

  • Chutes and transfer stations

  • Pipe supports and brackets

  • Replacement machine components

  • Skids and modular assemblies

  • Tanks and fabricated vessels

  • Maintenance platforms

  • Mechanical layouts

  • Custom industrial equipment

The surrounding BIM or point-cloud data provides the spatial context. SolidWorks provides the detailed mechanical design and fabrication information.

This approach allows the mechanical assembly to be designed around actual site conditions rather than relying only on old drawings or isolated measurements.

Mechanical Engineering Consulting

Reality capture and 3D modelling are most useful when they are connected to a clear engineering objective.

Mechanical Engineering consulting can assist with defining the design problem, reviewing site constraints, developing suitable concepts and preparing practical engineering deliverables.

Mechanical engineering consulting may include:

  • Mechanical equipment design

  • Brownfield modification planning

  • Reverse engineering

  • Fabrication design

  • Machinery layouts

  • Materials-handling equipment

  • Chute and hopper design

  • Pipework routing and support design

  • Access and maintenance reviews

  • Design verification

  • Finite element analysis

  • Engineering drawings and documentation

  • Coordination with fabricators and site teams

The engineering process should begin by understanding how the equipment operates, what loads are involved, how it will be installed and how it will be maintained.

The design model must therefore represent more than geometry. It should also consider function, safety, fabrication, assembly, access and expected operating conditions.

A Practical Digital Engineering Workflow

A typical project combining 3D scanning, SolidWorks and mechanical engineering consulting may follow the process below.

1. Define the engineering problem

The project begins by confirming what must be designed, replaced, modified or verified.

This may include identifying the required deliverables, modelling accuracy, operating conditions, design loads and applicable engineering standards.

2. Capture the existing site

The relevant machinery, structures and surrounding interfaces are captured using 3D laser scanning.

Additional photographs, site notes and critical measurements may also be collected.

3. Register and review the point cloud

The scan positions are combined into a coordinated point cloud.

The data is reviewed for coverage, alignment and suitability for the intended engineering work.

4. Build the required model

Relevant geometry is recreated using SolidWorks, Revit, AutoCAD or other suitable modelling software.

Only the level of detail needed for the project should be modelled.

5. Develop the engineering solution

Design concepts are developed while considering:

  • Existing-site constraints

  • Fabrication methods

  • Installation access

  • Equipment clearances

  • Maintenance requirements

  • Structural and mechanical loads

  • Safety and guarding

  • Relevant standards

6. Verify the design

The proposed design can be overlaid or compared against the point cloud to check fit, alignment and potential clashes.

Where required, calculations or finite element analysis can also be undertaken.

7. Prepare drawings and deliverables

The final output may include general arrangements, fabrication drawings, part drawings, assemblies, bills of materials and digital models.

Benefits of Combining Scanning and Engineering Design

Combining 3D laser scanning with SolidWorks and mechanical engineering consulting can provide several advantages.

Improved dimensional confidence

The design is based on measured site geometry rather than assumptions or incomplete drawings.

Reduced site rework

Potential clashes and fit-up problems can be identified before fabrication or installation.

Better project coordination

Designers, engineers, fabricators and site teams can work from coordinated digital information.

Fewer return visits

A comprehensive point cloud may allow additional measurements to be taken digitally after the site visit.

More practical designs

The surrounding equipment, structures and access conditions can be considered throughout the design process.

Improved fabrication information

SolidWorks models can be used to prepare detailed assemblies, part drawings and bills of materials.

Applications Across Industry

This workflow can support projects in:

  • Manufacturing facilities

  • Mining and mineral processing

  • Materials handling

  • Water and wastewater infrastructure

  • Food and beverage production

  • Ports and bulk-handling terminals

  • Commercial building services

  • Power and energy facilities

  • Mechanical plant rooms

  • Brownfield industrial sites

It is particularly effective where equipment must be installed within an existing operating environment.

Engineering-Led Reality Capture

A successful scanning project requires more than collecting a point cloud.

The scanning plan should reflect the final engineering purpose. The operator must understand which areas, interfaces and features are critical to the design.

For example, a mechanical designer may need clear scan coverage of:

  • Bolt-hole positions

  • Equipment centre lines

  • Flange locations

  • Support interfaces

  • Floor and platform levels

  • Structural members

  • Maintenance-removal paths

  • Nearby pipework and services

  • Crane and lifting access

An engineering-led approach helps ensure that the captured data is suitable for the next stage of the project.

From Existing Site to Fabrication-Ready Design

The combination of 3D laser scanning, Scan to BIM and SolidWorks creates a connected workflow from reality capture through to mechanical design.

The process can begin with an existing Melbourne facility, convert the measured environment into a coordinated digital reference and then use that information to develop practical engineering solutions.
