How Does 3D Drafting Work? Ettol’s Quick Guide to 3D Drafting and Modelling

If you’ve ever been curious as to how 3D modelling and drafting work, you wouldn’t be alone. While most have seen the outcome in the form of intricate 3D models, most people don’t understand the complex process that goes into creating that model. The team at Ettol have been doing 3D drafting and modelling in Perth for a little while now, and our team of engineers have over 40 years of combined experience. We’re here to share with you a brief overview of how we bring your ideas, products, and inventions to 3-dimensional life.

The Difference Between Modelling and Drafting

While the two are sometimes used interchangeably, drafting and modelling are two separate phases of the design process.

  • 3D Drafting in Perth: Drafting is a design that doesn’t use any implementation-specific or technology-specific details.
  • 3D Modelling in Perth: A 3D model is a design that includes implementation and technology-specific details, and is often more accurate than a draft. 

The Process of 3D Drafting

3D drafting in Perth is achieved through the utilisation of computer-aided design (CAD) software. A couple of decades ago, engineering drafts were all hand-drawn, which took countless hours of calculations, measurements, and careful drawing. Not to mention the time needed to make edits and updates. Nowadays, CAD technology simplifies the process.

  • Problem definition: Before we can begin designing anything, the engineers at Ettol will first clearly define the problem you’re trying to solve. 
  • Brainstorming: From there, we brainstorm innovative engineering solutions tailored specifically to your problem. 
  • Preliminary design: The engineers at Ettol look at creating sketches and drawings as part of the initial design phase.
  • Drafting: After choosing the most vital parts of our initial designs, we input them into our cutting-edge CAD software to create a 2D draft of your design.
  • Rendering: We can then turn that 2D design into a 3D draft. While it won’t include any implementation or technology-specific details, it’s still an effective way to present ideas and concepts. 



The Process of 3D Modelling

Unlike 3D drafting, 3D modelling can use pre-existing designs. However, you can do the full design process within the CAD software if you’d prefer.

  • Making the parts. If your design or product involves a lot of intricate details, we’ll create part files.
  • Bringing sketches into 3D. Once we’ve drawn a sketch or imported an existing sketch, we make it 3D. We do this by using extrude, revolve, sweep, or loft features.
  • Modification and refinement. We can then refine our basic 3D shape by manipulating it with various tools. This provides details like rounding edges, hollowing out interiors, placing holes, and adding reflections. 
  • Assembling. We then place part files onto the 3D shape we’ve built and joined the pieces together. 
  • Create movement. If you need your model to move at all, we then use CAD software to program motion.
