What Is Scan-to-CAD?
Scan-to-CAD is the process of converting three-dimensional measurement data from an existing object or environment into a usable computer-aided design model.
Industrial 3D laser scanners capture millions of measurement points, creating a point cloud that represents the visible geometry of existing equipment, structures or installations.
This information can then be used as a dimensional reference to develop 3D CAD models.
Unlike a point cloud, which represents measured surfaces, a CAD model contains defined geometric features that can be used for engineering design, manufacturing and technical documentation.
Depending on project requirements, Scan-to-CAD deliverables may include:
- SolidWorks 3D part models
- Mechanical equipment assemblies
- Structural steelwork models
- Pipework routing models
- STEP and Parasolid files
- General arrangement drawings
- Fabrication and manufacturing drawings
- Installation layouts
- Reverse-engineered components
- Existing-condition engineering models
The required level of detail is established according to the intended application, including whether the model will be used for visualisation, design modification, fabrication or engineering analysis.

For complex installations, a registered point cloud provides a three-dimensional reference that can help reduce uncertainty during engineering modelling and fabrication planning.
3D Scanning for Fabrication in Chatswood
Fabrication projects frequently require new components to connect to existing structures, machinery or equipment.
When original drawings are unavailable or no longer reflect actual site conditions, obtaining accurate dimensional information becomes particularly important.
Hamilton By Design provides 3D scanning and engineering modelling services to support fabrication projects involving existing industrial infrastructure.
Our services can capture:
- Structural beams and columns
- Existing equipment supports
- Pipework and flange locations
- Machinery mounting arrangements
- Structural connection interfaces
- Access platforms and walkways
- Equipment installation envelopes
- Existing fabricated assemblies
The captured point cloud can be used to develop CAD geometry and fabrication drawings that account for existing site conditions.
This approach is particularly useful for brownfield engineering projects where new fabricated components must integrate with established infrastructure.
Critical fabrication dimensions, connection details and tolerances are identified and verified according to the requirements of the project.
Reverse Engineering of Machinery and Mechanical Components
Reverse engineering involves recreating the geometry of an existing component or assembly when original CAD models or engineering drawings are unavailable.
Hamilton By Design provides mechanical reverse engineering services using 3D scanning, dimensional measurement and SolidWorks modelling.
Typical applications include:
- Replacement machinery components
- Existing fabricated assemblies
- Mechanical equipment modifications
- Pump and equipment components
- Machine guards and covers
- Brackets and support structures
- Existing equipment interfaces
- Custom fabricated components
- Obsolete equipment documentation
Depending on the size and complexity of the component, either terrestrial LiDAR scanning or handheld blue-laser scanning technology may be used.
For smaller components requiring higher-detail measurement, Hamilton By Design uses a Revopoint MetroY Ultra handheld blue-laser scanner.
The captured geometry can then be recreated as a CAD model suitable for the agreed engineering or manufacturing application.
Where necessary, additional measurements and engineering interpretation are used to establish features that cannot be reliably determined from scanning alone.
SolidWorks 3D CAD Modelling and Engineering Drawings
Hamilton By Design uses SolidWorks to develop mechanical engineering models, assemblies and drawings from captured scanning data.
SolidWorks models can be used to support design modifications, component development, equipment installation and manufacturing documentation.
Our CAD modelling capabilities include:
- Parametric mechanical part modelling
- Multi-component assembly modelling
- Structural steelwork geometry
- Machinery and equipment layouts
- Pipework and mechanical services models
- Reverse-engineered components
- Equipment support structures
- General arrangement drawings
- Fabrication drawings
- Engineering design modifications
Where required, models can be exported in neutral formats such as STEP and Parasolid for use in other CAD systems.
For projects requiring engineering analysis, the CAD geometry can also be developed or simplified to support finite element analysis, subject to the agreed scope.
Structural Steelwork Scan-to-CAD and Fabrication
Existing structural steelwork often presents dimensional challenges when new platforms, equipment supports or structural modifications are required.
Traditional site measurements may not fully capture the relationships between beams, columns, connection points and surrounding equipment.
Hamilton By Design provides structural steelwork scanning and CAD modelling services to support fabrication and installation planning.
Typical applications include:
- Structural steelwork modifications
- New equipment support frames
- Existing beam and column documentation
- Access platforms and walkways
- Industrial stair and ladder installations
- Crane and lifting equipment support interfaces
- Fabricated steelwork connections
- Structural clearance assessments
The registered point cloud can be used to develop a three-dimensional representation of existing steelwork.
Proposed components can then be modelled relative to the captured geometry to assist with installation planning and identify potential dimensional conflicts.
Where structural design verification or engineering certification is required, this is addressed as a separate engineering scope.
Pipework Scan-to-CAD and Fabrication Drawings
Pipework modifications are common in industrial facilities, commercial mechanical plantrooms and manufacturing environments.
Existing pipework may be congested, difficult to access or installed in arrangements that differ from original drawings.
Hamilton By Design provides 3D scanning and mechanical engineering services to support pipework routing, modifications and fabrication planning.
Our services can assist with:
- Existing pipework geometry capture
- Pipe centreline and route modelling
- Flange and equipment interface documentation
- Pipe support location identification
- New pipework routing
- Mechanical services coordination
- Installation clearance assessments
- General arrangement drawings
- Pipework fabrication documentation
Using the registered point cloud as a dimensional reference, proposed pipework routes can be developed within a three-dimensional CAD environment.
This allows engineers and fabrication contractors to consider existing structures, equipment, access requirements and available installation space.
Critical pipework dimensions, flange orientations and fabrication tolerances can be verified separately where required.
Mechanical Plantroom Modifications and Equipment Installation
Commercial buildings throughout Chatswood, Artarmon, St Leonards and North Sydney contain mechanical plantrooms supporting HVAC systems, pumps, ventilation equipment and building services infrastructure.
When existing equipment requires replacement or modification, accurate site measurements can help reduce installation uncertainty.
Hamilton By Design provides 3D scanning and Scan-to-CAD modelling for mechanical plantroom upgrades.
Typical applications include:
- Pump replacement projects
- Chilled-water pipework modifications
- HVAC equipment installation
- Mechanical equipment support frames
- Equipment access and maintenance clearance assessments
- Existing plantroom layout documentation
- Pipework and structural interface coordination
The captured geometry can be used to develop engineering models that represent existing equipment and surrounding infrastructure.
Proposed modifications can then be assessed within the available installation envelope before fabrication begins.
From Point Cloud to Fabrication Drawings
A registered point cloud provides a detailed record of visible existing geometry, but it does not automatically constitute a fabrication-ready engineering model.
Hamilton By Design follows a structured Scan-to-CAD process to develop practical engineering deliverables.
Step 1 – Project Scope and Fabrication Requirements
We review the intended fabrication or engineering application, including the required geometry, critical interfaces, tolerances and final deliverables.
This helps establish the appropriate scanning and modelling methodology.
Step 2 – 3D Scanning and Site Measurement
Existing equipment, structures and surrounding geometry are captured using suitable 3D scanning equipment.
Additional measurements may be undertaken where critical dimensions cannot be reliably established from scanning alone.
Step 3 – Point Cloud Registration and Processing
Individual scans are aligned and processed into a registered point cloud.
The data is reviewed for coverage, registration quality and suitability for the agreed engineering application.
Step 4 – 3D CAD Model Development
The registered point cloud is imported into the engineering workflow and used as a dimensional reference for CAD modelling.
Geometry is developed according to the required level of detail and intended use.
Step 5 – Engineering and Fabrication Documentation
Where required, general arrangement drawings, component drawings and fabrication documentation are prepared from the CAD model.
Critical dimensions, manufacturing requirements and engineering assumptions are documented according to the agreed scope.
Step 6 – Digital Delivery
Final files are supplied in agreed formats suitable for the client’s design, engineering or manufacturing workflow.
