Reducing fabrication uncertainty, improving equipment fit-up and supporting mining shutdown planning. The Challenge of Modifying Existing Mining Equipment Mining processing plants rarely remain exactly as they were originally designed. Over time, conveyors are modified, transfer chutes are replaced, platforms are installed and mechanical equipment is upgraded to meet changing production requirements. Unfortunately, the original engineering drawings may not reflect these modifications. For maintenance superintendents, project engineers and shutdown planners, this creates an important question: How can new equipment be designed and fabricated to fit an existing mining plant when the installed geometry is uncertain? One practical solution is to use 3D LiDAR scanning before engineering design begins. Hamilton By Design combines 3D scanning, point cloud processing, mechanical engineering and CAD modelling to support mining equipment modifications across Australia. Read the full engineering ...

Computer Aided Drafting – Modern Engineering Design with CAD and 3D Modelling
Computer Aided Drafting (CAD) has transformed the way engineering and design projects are developed. What was once done manually on drawing boards is now completed using advanced digital tools that allow engineers to create accurate 2D drawings and intelligent 3D models.
Today, CAD is not just about drafting—it is a critical part of a broader digital engineering workflow that supports design, analysis, and manufacturing.
Computer-aided design enables engineers to create, modify, and optimise designs digitally, improving accuracy and efficiency while reducing reliance on manual processes.
At Hamilton By Design, CAD is integrated with engineering expertise and modern technologies to deliver practical, real-world solutions for industrial and mechanical projects.
What Is Computer Aided Drafting?
Computer Aided Drafting (CAD or CADD) refers to the use of computer software to produce technical drawings and 3D models.
These drawings are used to communicate design intent, including:
Dimensions and tolerances
Material specifications
Assembly details
Fabrication requirements
CAD systems allow engineers to develop both 2D drawings and 3D models, enabling better visualisation and coordination before any physical work begins.
This shift from manual drafting to digital modelling has significantly improved design quality, productivity, and collaboration across engineering projects.
From Drafting to Digital Engineering
Traditional drafting focused primarily on creating drawings. Modern CAD workflows go much further.
Today, CAD supports:
3D modelling and assemblies
Design validation and simulation
Coordination between disciplines
Integration with manufacturing processes
Rather than producing static drawings, engineers now develop intelligent digital models that can be modified, analysed, and optimised throughout the project lifecycle.
This evolution has made CAD an essential tool across industries including manufacturing, mining, construction, and infrastructure.
The Role of SolidWorks in Modern CAD
One of the leading CAD platforms used in engineering today is SolidWorks.
When combined with engineering expertise, SolidWorks becomes more than just a drafting tool—it becomes a platform for delivering complete, buildable design solutions.
Why Accurate Data Matters in CAD
One of the biggest challenges in engineering design is ensuring that drawings reflect real-world conditions.
Many projects still rely on:
Outdated drawings
Manual measurements
Incomplete documentation
This can lead to errors, rework, and costly delays.
To overcome this, modern CAD workflows increasingly rely on accurate site data, often captured using 3D laser scanning.
Integrating CAD with 3D Laser Scanning
At Hamilton By Design, we combine CAD with 3D laser scanning (LiDAR) to create a fully integrated design workflow.
By working from real-world geometry, we significantly improve design accuracy and project outcomes.
Scan to Model – A Modern Workflow
Our approach follows a structured process:
Scan → Register → Model → Design → Deliver
This workflow ensures that:
Designs are based on verified data
Models reflect actual site conditions
Engineering decisions are informed and accurate
For complex environments such as industrial plants, this approach is critical to reducing risk and ensuring successful project delivery.
Applications of Computer Aided Drafting
CAD is widely used across a range of industries and applications, including:
Mechanical engineering and equipment design
Structural steel and infrastructure
Pipework and plant layout
Manufacturing and product design
Mining and materials handling systems
CAD models allow engineers to visualise, test, and refine designs before fabrication, improving overall efficiency and reducing errors.
Reverse Engineering and Existing Plant
In many projects, original drawings are missing or no longer accurate.
CAD plays a key role in reverse engineering by enabling engineers to:
Recreate existing geometry
Develop updated 3D models
Produce new fabrication drawings
Modify designs for upgrades
When combined with 3D scanning, this process becomes even more powerful—allowing accurate digital models to be created from real-world assets.
Benefits of Computer Aided Drafting
The adoption of CAD has delivered significant benefits across engineering and manufacturing industries.
These include:
Improved accuracy and precision
Faster design development
Better communication through clear documentation
Reduced design errors and rework
Enhanced collaboration between teams
CAD has largely replaced manual drafting because it allows engineers to create more detailed and efficient designs, improving overall project outcomes.
A Practical, Engineering-Led Approach
At Hamilton By Design, CAD is not treated as a standalone service—it is part of a broader engineering solution.
Our approach ensures that every design:
Is based on accurate data
Reflects real-world conditions
Is practical to fabricate and install
Supports long-term operation and maintenance
By combining CAD, SolidWorks, and 3D scanning, we deliver solutions that work in practice—not just on paper.
Final Thoughts
Computer Aided Drafting has evolved from simple 2D drawing into a powerful digital engineering tool.
When combined with modern technologies such as 3D modelling and laser scanning, CAD enables engineers to design with greater accuracy, efficiency, and confidence.
Whether you are developing new equipment, upgrading existing plant, or reverse engineering legacy systems, an integrated CAD workflow provides the foundation for successful project delivery.
For Coal Wash Plant Reliability and Maintenance Coal Handling and Preparation Plants (CHPPs) form the backbone of Australia’s coal production network — from the Bowen Basin to the Hunter Valley and the Central West. Yet these plants face relentless mechanical and environmental challenges. Every tonne of coal that passes through generates impact, vibration, slurry, and corrosion — all of which degrade mechanical systems and shorten asset life. At Hamilton By Design, we specialise in helping operators and contractors transition from reactive maintenance to precision-based, data-driven engineering. Through advanced 3D scanning, mechanical design, finite element analysis (FEA) , and practical shutdown planning, our goal is simple: design for reliability, maintain for efficiency, and execute for safety . 1. Designing for Reliability Most unplanned failures in a coal wash plant can be traced back to early design decisions. Poor geometry in chutes, undersized bearings, or inadequat...
3D Scanning Perth: Engineering-Grade LiDAR for Mining, Industrial and Fabrication Projects Accurate existing-condition information is essential when planning modifications to operating plants, mining facilities, structural steel, pipework or industrial equipment. Traditional site measurements can be slow and may not capture every obstruction, connection point or interface.
