Engineering-Led 3D LiDAR Scanning | Scan-to-CAD | Mechanical Design | Reverse Engineering | Fabrication Drawings
WE SCAN → WE DESIGN → WE ENGINEER → IT FITS. IT WORKS.
We Are Not Surveyors or Cameramen. We Are Engineers.
At Hamilton By Design, we don’t approach 3D scanning as a photography exercise or simply a means of collecting millions of measurement points.
We are engineers who use 3D scanning to solve engineering problems.
We understand numbers, dimensions, tolerances, mechanical interfaces and the engineering principles that determine whether components will fit together and function as intended.
A point cloud may contain millions of measurements, but those measurements only become valuable when they are interpreted correctly and applied to a practical engineering outcome.
We don’t just capture millions of points. We understand what those points mean.
Our responsibility extends beyond operating a scanner and delivering a point cloud. We consider the engineering requirements, critical dimensions, fabrication tolerances, mechanical interfaces and installation clearances that determine whether equipment can be successfully designed, manufactured and installed.
We don’t blame the scanner when something doesn’t fit. We take responsibility for understanding the measurements, verifying critical dimensions and engineering the solution.
A scanner is a measurement tool. It is the engineer’s responsibility to understand its accuracy, limitations and suitability for the intended application.
Our engineering-led approach combines 3D LiDAR scanning, dimensional verification, CAD modelling and mechanical engineering to help reduce fabrication errors, installation conflicts and costly rework.
We don’t simply document what exists. We engineer what comes next.
3D Scanning for Engineering Outcomes — Not Just Point Clouds
Hamilton By Design provides engineering-grade 3D scanning services throughout Sydney, Greater Sydney and New South Wales.
Our services are designed for engineers, manufacturers, industrial operators, fabrication contractors, mining companies and asset owners who require more than a digital representation of an existing installation.
We use 3D LiDAR scanning as part of an integrated engineering process to support:
- Mechanical equipment design and modification
- Industrial plant upgrades and brownfield projects
- Conveyor and transfer chute design
- Pipework modifications and spool development
- Structural steelwork and equipment supports
- Mechanical component reverse engineering
- Machine guarding and safety improvements
- Fabrication and assembly drawings
- Installation planning and dimensional verification
- Engineering analysis and design assessment
Our objective is to establish accurate existing-condition information that can be used to develop practical engineering solutions.
The scanning process is not the end of the project. It is the beginning of an informed engineering design process.
Why Engineering Knowledge Matters Before Scanning Begins
Not every point in a point cloud has the same engineering significance.
A large industrial installation may contain millions of measured points, but a relatively small number of critical interfaces can determine whether a proposed modification will fit.
These may include:
- Mounting hole positions and bolt patterns
- Equipment centre lines and shaft alignments
- Pipe flange locations and orientations
- Structural steel connection points
- Conveyor belt elevations and transfer positions
- Installation and maintenance clearances
- Existing machinery envelopes
- Access requirements for fabrication and assembly
An engineer understands why these dimensions matter and how measurement uncertainty may affect the final design.
At Hamilton By Design, we consider the intended engineering outcome before determining the scanning methodology.
This allows us to identify where terrestrial LiDAR scanning is appropriate and where additional close-range scanning, direct measurement or dimensional verification may be necessary.
The objective is not to collect the greatest number of points. It is to collect the right information for the engineering problem.
WE SCAN — Engineering-Grade 3D LiDAR Scanning
Hamilton By Design uses engineering-grade scanning equipment to capture existing industrial facilities, machinery, mechanical components and structural installations.
Our equipment include but not limited to:
FARO Focus S70 Terrestrial LiDAR Scanner
Used for capturing large industrial installations, buildings, structural steelwork, mechanical equipment, pipework and complex existing environments.
Revopoint MetroY Ultra Handheld Blue-Laser Scanner
Used for close-range measurement and reverse engineering of smaller mechanical components where higher-detail geometric capture is required.
The scanning equipment and methodology are selected according to the scale, accessibility, surface characteristics, accuracy requirements and intended engineering application.
Understanding Scanning Accuracy
Scanner specifications do not automatically establish the accuracy of every dimension derived from a point cloud.
Measurement uncertainty can be influenced by:
- Scanner selection and calibration
- Measurement distance and angle
- Surface characteristics and reflectivity
- Line-of-sight limitations
- Point cloud registration
- Environmental conditions
- Data processing and modelling methods
For this reason, Hamilton By Design considers the suitability of the measurement data for the intended design.
Where critical dimensions exceed the practical accuracy of terrestrial scanning, supplementary measurement or higher-accuracy scanning may be required.
Engineering accuracy is not simply a scanner specification. It is the result of an appropriate measurement and verification process.
WE DESIGN — Turning Point Clouds into Practical Engineering Models
Capturing existing geometry is only the first stage.
The next challenge is converting the measured information into CAD models and engineering drawings that can be used for design, manufacture and installation.
Hamilton By Design uses SolidWorks, Autodesk Inventor and AutoCAD to develop engineering geometry from registered point clouds and verified dimensional information.
Our Scan-to-CAD Capabilities
Mechanical Equipment Modelling
Creation of CAD models representing existing machinery, mechanical assemblies, equipment interfaces and industrial installations.
Reverse Engineering
Reconstruction of mechanical components and assemblies where original manufacturing drawings or CAD models are unavailable.
Conveyor and Transfer Chute Design
Development of new or modified equipment to interface with existing conveyors, structural steelwork and surrounding machinery.
Industrial Pipework Design
Modelling of existing pipework and development of proposed pipe routes, equipment connections and spool arrangements.
Structural and Mechanical Interfaces
Development of supports, brackets, equipment frames and mechanical connections based on measured existing geometry.
Fabrication Drawings
Preparation of general arrangement drawings, assembly drawings, component drawings and fabrication documentation.
Our modelling approach is based on the intended engineering application.
We do not necessarily model every visible surface or point. We develop the geometry required to support the agreed design, verification and manufacturing requirements.
WE ENGINEER — Understanding Why Components Fit and Function
Engineering involves more than producing a three-dimensional CAD model.
A model may appear geometrically correct on a computer screen while still presenting problems during fabrication or installation.
Hamilton By Design considers the engineering requirements that influence whether a proposed modification is practical.
Depending on the agreed project scope, these may include:
- Mechanical loads and operating conditions
- Material selection
- Structural and mechanical interfaces
- Dimensional tolerances
- Installation and assembly requirements
- Maintenance and operational clearances
- Fabrication methods
- Equipment alignment
- Mechanical functionality
- Applicable Australian Standards
- Engineering calculations and Finite Element Analysis
Our mechanical engineering capability allows scanning data to be integrated into the design and assessment process.
We Understand Numbers — Not Just Point Clouds
Engineering requires an understanding of the relationship between measurement accuracy, manufacturing tolerances and functional requirements.
For example, a terrestrial point cloud may provide suitable geometry for the layout of a large industrial plant.
However, the same data may not provide sufficient accuracy to establish the fit of a precision-machined shaft, bearing housing or close-tolerance mechanical connection.
An engineering-led approach recognises these differences.
Rather than assuming that every dimension in the point cloud is equally reliable, we identify which measurements are critical and determine how they should be verified.
We understand that a measurement is only useful when its accuracy is appropriate for the engineering decision being made.
IT FITS. IT WORKS. — The Engineering Outcome
The ultimate objective of our engineering-led 3D scanning process is not the number of scans completed or the size of the point cloud.
It is developing an engineering solution that can be manufactured, installed and operated as intended.
IT FITS.
A successful design must account for the existing installation.
This includes:
- Available space
- Mounting interfaces
- Equipment alignment
- Structural connections
- Fabrication tolerances
- Installation access
- Mechanical clearances
- Assembly requirements
By capturing and verifying critical dimensions before fabrication, we aim to reduce the likelihood of discovering dimensional conflicts during installation.
IT WORKS.
A component fitting into the available space does not necessarily mean it will function correctly.
Engineering design must also consider mechanical performance, operational requirements, loads, materials, safety and maintainability.
Hamilton By Design integrates these considerations into the agreed engineering design process.
Fit is a dimensional requirement. Function is an engineering requirement. Both matter.
Successful outcomes also depend on appropriate fabrication quality, installation controls and verification of the finished work.
We Don’t Blame the Scanner
A common problem in engineering projects occurs when discrepancies are discovered between the CAD model, fabricated component and existing installation.
These discrepancies may arise from incomplete measurement coverage, incorrect assumptions, registration errors, inappropriate tolerances or changes to the site after scanning.
Simply stating that the scanner produced the measurement does not resolve the engineering problem.
At Hamilton By Design, we recognise that scanners are tools and that engineering judgement is required to interpret their data.
Our approach is to:
- Understand the intended engineering outcome.
- Identify critical dimensions and interfaces.
- Select a suitable measurement methodology.
- Review the quality and limitations of the captured data.
- Verify dimensions where the engineering application requires it.
- Develop CAD models using appropriate design assumptions.
- Review installation clearances and mechanical interfaces.
- Document relevant tolerances, limitations and verification requirements.
We don’t treat the point cloud as an unquestionable source of truth. We assess whether the data is suitable for the engineering decision.
This is particularly important where components must be fabricated off-site and installed into an existing operating facility.
Engineering-Led Scanning for Brownfield Industrial Projects
Brownfield engineering projects involve modifications to existing installations, often where original drawings are incomplete or no longer represent actual site conditions.
Over time, industrial facilities undergo equipment replacements, structural modifications, pipework changes and maintenance repairs.
The resulting installation may differ substantially from the original design documentation.
Engineering-led 3D scanning provides a method of capturing accessible existing geometry and developing updated CAD information.
Example — Conveyor Transfer Chute Replacement
Consider an existing conveyor transfer chute requiring replacement within a congested industrial installation.
The new chute must interface with existing conveyors, supporting steelwork, mechanical equipment and maintenance access arrangements.
The engineering process may involve:
Stage 1 — Existing-Condition Scanning
Capture the surrounding steelwork, conveyor equipment, chute geometry and accessible installation interfaces.
Stage 2 — Dimensional Verification
Identify critical mounting positions, conveyor centre lines, clearances and connection dimensions requiring verification.
Stage 3 — Mechanical CAD Design
Develop the replacement chute geometry using the measured installation as a dimensional reference.
Stage 4 — Engineering Assessment
Consider loads, materials, structural interfaces, mechanical clearances and operational requirements.
Stage 5 — Fabrication Documentation
Prepare the agreed general arrangement, assembly and component drawings.
Stage 6 — Installation Review
Check the proposed equipment envelope and interfaces against the captured geometry and verified measurements.
This integrated process aims to identify potential dimensional and design conflicts before fabrication.
The value is not simply knowing what the existing chute looks like. It is understanding how the replacement chute must fit and function.
