How Point Clouds Support Brownfield Mechanical Design in Sydney
Brownfield mechanical design starts with understanding what is already installed.
Existing factories, processing plants, warehouses and industrial facilities often contain equipment, pipework and structural elements that have been modified over many years. The current installation may therefore be significantly different from the original drawings.
For a SolidWorks designer, incomplete or inaccurate site information can result in:
Design clashes
Incorrect equipment interfaces
Pipework misalignment
Fabrication errors
Installation delays
Additional site visits
Costly site modifications
Hamilton By Design provides 3D scanning services in Sydney to capture existing equipment, pipework, structures and surrounding site conditions as a measurable three-dimensional point cloud.
The point-cloud information can then be used as a reference for developing accurate SolidWorks models for brownfield mechanical design, equipment replacement, reverse engineering and fabrication planning.
What Is Brownfield Mechanical Design?
Brownfield mechanical design involves introducing new equipment or modifying existing plant within an operating facility.
Unlike a greenfield project, a brownfield designer must work around existing:
Mechanical equipment
Pipework and valves
Conveyors and chutes
Structural steel
Platforms and walkways
Handrails and guarding
Electrical cable trays
Ductwork
Tanks and vessels
Building columns and walls
Existing maintenance-access requirements
Space is often restricted, and the proposed design may need to connect directly to existing equipment.
Accurate existing-condition information is therefore essential before detailed SolidWorks modelling begins.
What Is a Point Cloud?
A point cloud is a three-dimensional collection of measured points captured by a laser scanner.
Each point represents a position on a visible surface. Millions of points are combined to create a detailed digital representation of the scanned area.
A point cloud may capture:
Equipment locations
Pipework routes
Flange positions
Structural members
Conveyor alignments
Platform levels
Floor elevations
Wall and roof geometry
Access clearances
Chute interfaces
Existing mechanical connections
The registered point cloud can be viewed, measured and used as a geometric reference during the SolidWorks design process.
Hamilton By Design provides industrial 3D scanning in Sydney for projects where reliable existing-condition data is required before mechanical design or drafting begins.
From Point Cloud to SolidWorks
A point cloud is not automatically a finished SolidWorks model.
The scan records the visible geometry of the existing plant. Relevant equipment, structures and interfaces can then be interpreted and recreated as usable CAD geometry.
Depending on the project, the SolidWorks model may include:
Equipment envelopes
Pipework centre lines
Flange and nozzle locations
Structural members
Platforms and access ways
Conveyor geometry
Chutes and transfer points
Tanks and vessels
Mechanical guards
Building interfaces
Not every object in the point cloud needs to be modelled.
For many brownfield projects, only the geometry that affects the proposed design needs to be converted into SolidWorks. This selective approach can provide the required design context without unnecessarily modelling the entire facility.
How Point Clouds Support SolidWorks Mechanical Design
1. Creating an Accurate Existing-Conditions Model
The first benefit of 3D scanning is the creation of a measurable digital record of the existing facility.
Instead of relying only on photographs, tape measurements or outdated drawings, the SolidWorks designer can review the surrounding equipment and structures in three dimensions.
The point cloud can be used to establish:
Equipment positions
Structural locations
Platform elevations
Pipework routes
Available design space
Connection-point relationships
Access and maintenance clearances
This provides a more reliable foundation for the proposed mechanical design.
2. Supporting Equipment Replacement
Replacing an existing pump, fan, conveyor, vessel or processing machine may appear straightforward, but new equipment rarely has exactly the same dimensions or connection arrangement.
Replacement equipment may have different:
Overall dimensions
Baseplate sizes
Motor positions
Flange locations
Nozzle orientations
Maintenance envelopes
Access requirements
Supporting-frame arrangements
A point cloud allows the existing equipment and surrounding area to be recreated within SolidWorks.
The proposed replacement equipment can then be positioned within the existing environment to assess whether it fits and identify which surrounding services may need to be modified.
3. Verifying Mechanical Tie-In Locations
Brownfield modifications frequently require new equipment or pipework to connect to existing plant.
Point clouds can help establish the locations of:
Existing flanges
Pipe centre lines
Equipment nozzles
Conveyor discharge points
Structural fixing locations
Floor and platform levels
Chute inlets and outlets
Existing mounting points
These locations can be referenced within the SolidWorks model when developing the proposed arrangement.
Critical fabrication and installation dimensions should still be verified to the accuracy required by the project, but the point cloud provides a strong basis for design development.
4. Developing New Pipework Routes
Routing new pipework through an operating facility can be difficult when the available space is already occupied by existing services.
A point cloud can help the SolidWorks designer review:
Available pipe routes
Existing structural obstructions
Nearby cable trays
Valve-access requirements
Potential support locations
Equipment-maintenance zones
Congested service areas
Proposed connection points
The new pipe route can be modelled within the existing scanned environment to identify potential spatial conflicts before installation.
Pressure design, pipe flexibility, thermal expansion, support loads and applicable piping standards must still be assessed separately as part of the engineering process.
5. Supporting Conveyor and Chute Modifications
Conveyor and chute modifications often involve complex relationships between mechanical equipment, structural steel and access systems.
The design may need to account for:
Conveyor centre lines
Pulley locations
Belt elevations
Discharge points
Existing chute geometry
Supporting steelwork
Maintenance platforms
Access clearances
Adjacent equipment
The point cloud provides the geometric context required to develop a new chute, hood, skirt, guard or conveyor modification within SolidWorks.
This is particularly valuable where original drawings are incomplete or no longer reflect the installed plant.
6. Checking for Design Clashes
A proposed SolidWorks design can be compared against the existing point-cloud environment to identify possible clashes.
Potential conflicts may involve:
Existing pipework
Structural beams
Electrical cable trays
Platforms and handrails
Ductwork
Mechanical equipment
Building walls
Roof structures
Maintenance-access areas
Identifying these issues during the design stage allows the proposed arrangement to be revised before fabrication begins.
This can reduce the likelihood of components being modified or remade on site.
7. Supporting Reverse Engineering
Point clouds can also support reverse engineering when an existing component or assembly needs to be reproduced, modified or incorporated into a new design.
Typical applications include:
Existing guards
Chutes and hoppers
Equipment frames
Access platforms
Pipe supports
Conveyor components
Machinery enclosures
Brackets and mounting arrangements
Replacement mechanical assemblies
The required geometry can be recreated in SolidWorks and used to develop replacement parts, modified assemblies or fabrication drawings.
The level of detail required should be determined by the intended use of the model.
8. Improving Fabrication Planning
Fabricators need clear information about how a new mechanical item will connect to the existing installation.
A scan-supported SolidWorks model can help communicate:
Connection locations
Overall dimensions
Interface geometry
Equipment orientation
Structural relationships
Access restrictions
Assembly requirements
Installation considerations
Fabrication drawings can then be developed from the approved SolidWorks model.
Where installation tolerances are required, the design may incorporate:
Slotted holes
Adjustment plates
Site-fit sections
Removable connections
Nominated verification dimensions
Final site-measure requirements
9. Reducing Repeat Site Visits
Industrial site access can involve considerable time and cost.
A site visit may require:
Travel
Site inductions
Permits
Escorts
Shutdown coordination
Elevated-work access
Production-area restrictions
Safety documentation
Traditional measurement methods can result in another site visit when a required dimension is missed.
Capturing a comprehensive point cloud during the initial visit allows many additional dimensions to be reviewed after leaving the site.
Return visits may still be required for concealed conditions, critical fabrication interfaces or plant changes made after the scanning date.
Typical Brownfield Applications

Equipment replacement
Pump and motor installations
Pipework modifications
Flange and valve tie-ins
Conveyor upgrades
Chute replacement
Mechanical guarding
Access-platform modifications

Ductwork routing
Equipment-support frames
Reverse engineering

A Typical 3D Scanning to SolidWorks Workflow
Stage 1 — Define the Project Requirements
The scan area, required accuracy and intended use of the information are identified.
The project may involve:
One machine
A section of pipework
A conveyor-transfer area
A production line
An equipment room
A larger industrial facility
The intended design outcome should be understood before scanning begins.
Stage 2 — Complete the Sydney Site Scan
The laser scanner is positioned at multiple locations around the required equipment and surrounding area.
The scan positions overlap, allowing the individual scans to be registered into a coordinated point cloud.
The scanning plan should capture both the item being modified and the surrounding geometry that may affect the design.
Stage 3 — Register the Point Cloud
The individual scans are processed and combined.
The registered point cloud is reviewed for:
Coverage
Alignment
Usable line of sight
Missing areas
Registration quality
Suitability for the intended design work
Common point-cloud formats may include E57, RCP or RCS files.
Stage 4 — Develop the Existing SolidWorks Model
Relevant equipment, pipework and structures are recreated from the point cloud.
The existing-condition model may be simplified and include only the items that affect the proposed design.
This helps keep the SolidWorks assembly manageable while preserving the required geometric context.
Stage 5 — Develop the Proposed Design
The proposed equipment or mechanical modification is designed within the existing-condition model.
The SolidWorks design can be reviewed for:
Fit
Connections
Clearances
Access
Maintenance requirements
Potential clashes
Fabrication feasibility
Installation considerations
Stage 6 — Produce Drawings and CAD Deliverables
Depending on the agreed scope, deliverables may include:
Registered point-cloud files
SolidWorks parts
SolidWorks assemblies
STEP files
SAT files
Parasolid files
AutoCAD drawings
General-arrangement drawings
Sections and elevations
Fabrication drawings
Bills of materials
Existing-condition models
The required file formats and modelling detail should be agreed at the beginning of the project.
What a Point Cloud Cannot Confirm
A laser scan captures visible surface geometry, but it does not automatically confirm:
Material grades
Pipe wall thickness
Internal corrosion
Structural capacity
Weld quality
Hidden reinforcement
Operating pressure
Equipment performance
Underground services
Concealed construction
Compliance with applicable standards
These matters may require additional drawings, inspections, calculations, testing or information from the asset owner.
Point clouds should therefore be treated as an accurate source of visible dimensional information rather than a complete engineering assessment.

Frequently Asked Questions
Can a point cloud be imported directly into SolidWorks?
Point-cloud data generally requires processing before it can be used effectively for detailed SolidWorks design.
The scan can be retained as a reference, while relevant equipment, structures and connection points are recreated as usable SolidWorks geometry.
Does everything in the scanned area need to be modelled?
No.
Only the equipment and geometry that affect the proposed design may need to be converted into SolidWorks.
Selective modelling can reduce unnecessary design time while providing enough detail for interface design, equipment positioning and clash review.
Can 3D scanning replace all manual measurements?
Not always.
Scanning can greatly improve dimensional coverage, but critical interfaces, concealed features and high-precision fabrication connections may still require direct verification.
The required verification method depends on the project tolerances and the consequences of an incorrect dimension.
How accurate is 3D scanning for mechanical design?
The achievable accuracy depends on factors including:
Scanner type
Scan distance
Surface properties
Site conditions
Registration method
Required deliverable
Project tolerance
Accuracy requirements should be discussed before scanning, particularly where new components will be fabricated to connect directly to existing equipment.
Can an operating factory be scanned?
In many cases, yes.
The work must be planned around the site’s safety, access and operational requirements.
Moving machinery, vehicles, dust, steam, vibration and restricted access may affect the scanning plan and data quality.
Can point clouds support fabrication drawings?
Yes.
A point-cloud-derived SolidWorks model can provide the basis for fabrication-drawing development.
The design should still incorporate appropriate installation tolerances, verification dimensions and engineering requirements.
