3D CAD MODELLING

3D CAD Modelling Services – Professional Design, Engineering & Technical Drafting

Introduction to the Service

3D CAD (Computer-Aided Design) has transformed the way products are conceptualised, designed, and manufactured. Modern engineering and fabrication industries rely heavily on accurate digital models to streamline production, reduce errors, and improve efficiency. At Draftings Australia, we specialise in delivering high-quality 3D CAD Modelling Services that support every stage of the design cycle—from concept development through to manufacturing.

Our team of experienced engineers and drafters uses industry-leading CAD software to generate detailed, functional, and accurate 3D models. These models form the foundation of your engineering drawings, prototypes, visualisations, and product documentation. Whether you require complex assemblies, precision components, or industrial equipment layouts, we offer a reliable, efficient, and cost-effective drafting solution tailored to your needs.

What is a 3D CAD Modelling Service?

A 3D CAD Modelling Service involves creating digital three-dimensional representations of components, parts, and assemblies using professional CAD tools such as SolidWorks, Autodesk Inventor, CATIA, and Creo (Pro-E). These models replicate real-world objects with exact dimensions, design intent, and geometric accuracy.

By developing a 3D model first, we can generate all downstream technical outputs, including:

• Fully dimensioned 2D engineering drawings (AS/ISO standard compliant)
• Photorealistic renders and design visualisations
• 3D print-ready files (STL)
• Assembly simulations, animations, and exploded views
• Interference and collision checks
• BOM (Bill of Materials) generation

3D modelling supports parametric and direct (explicit) modelling approaches:

• Parametric modelling retains design intent and allows easy modification based on and geometric relationships.
• Direct modelling enables quick edits without relying on feature history, ideal for conceptual and fast-turnaround projects.

This combination allows engineers to design smarter, iterate faster, and produce highly accurate documentation.

What 3D CAD Modelling Services Does Draftings Australia Offer?

At Draftings Australia, almost all of our technical drawings and documentation begin with a 3D model. While we still use 2D CAD (AutoCAD) for simple schematics, electrical layouts, and basic MEP drawings, the majority of our work is driven by advanced 3D solid modelling.

Our primary 3D CAD services include:

• Manufacturing Drawings
• Fabrication Drawings
• Patent Drawings
• Datasheets
• Shop Drawings
• Renders & Product Visualisations
• Mechanical Design & Assembly Modelling
• Reverse Engineering Models
• Prototype & 3D Print Modelling

Design modifications are completed directly in the 3D model, ensuring the associated drawings update automatically, saving significant time and reducing revision errors.

We primarily work with SolidWorks and hold multiple licensed seats supplied by our authorised VAR.
