About Me
I am a Mechanical Engineering Draftsperson with more than 19 years of Australian industry experience, specialising in mechanical CAD modelling, drafting, detailing, and manufacturing documentation.
Through RN Aus Drafting, I provide 3D CAD modelling and technical drafting services based on design requirements, specifications, dimensions, sketches, mark-ups, reference information, and engineering direction supplied or approved by the client and/or their nominated engineers.
My services include the preparation of assembly drawings, manufacturing drawings, fabrication drawings, and other technical documentation to support manufacturing, fabrication, assembly, installation, and project documentation requirements across mechanical, mining, rail, manufacturing, marine interior, and industrial sectors.
My focus is on preparing clear, practical, and production-ready drawings that help clients communicate design intent, support workshop manufacture, and maintain reliable project documentation.

Professional Background
Across my career, I have worked in mechanical drafting and design support roles for Australian engineering, manufacturing, and industrial companies. These roles have given me strong practical experience in 3D CAD modelling, mechanical detailing, manufacturing drawings, fabrication documentation, BOM preparation, DXF/DWG outputs, and drawing control.
Previous roles include:
Floveyor Pty Ltd — Designer, Technical & Sales
Prepared equipment layouts, product modifications, configurations, manufacturing drawings, assembly drawings, and SolidWorks PDM documentation for bulk materials handling equipment.
Wabtec / Track IQ — Mechanical Engineering Design Draftsperson
Developed large SolidWorks assembly models, mechanical drawings, sheet metal components, BOMs, DXF/DWG files, and manufacturing documentation for rail-related equipment and locomotive vision system projects.
Freelance Engineering Design & Drafting Professional
Provided mechanical drafting and CAD documentation support for mining-related products including Monowills barriers, stanchions, stairways, grating, access platforms, civil drainage products, and FRP components.
Webforge / Valmont — Mechanical Engineering Draftsperson
Produced fabrication drawings, DXFs, workshop documentation, and CAD drafting for grating, walkways, stairways, safety barriers, platforms, access covers, and drainage grates used across mining, industrial, and offshore projects.
Beurteaux Pty Ltd — Mechanical Engineering Design Draftsperson
Worked in an engineering and manufacturing environment specialising in marine interior projects. Prepared mechanical assembly drawings, sheet metal documentation, CNC manufacturing drawings, and production drawings for components used in marine interior systems.
This background gives RN Aus Drafting a strong practical understanding of workshop requirements, manufacturing processes, fabrication constraints, and the level of drawing clarity required for production.
