Long gone are the days where design activities were completed using pencil and paper on a drafting board. The evolution of computers in the 1980s helped to introduce a complete paradigm shift. Computer-aided drafting (CAD) became more and more commonplace as users realized the benefits and cost savings over the old way of doing things.
If anything can be said about technology, it’s that it certainly doesn’t stand still. The rudimentary CAD in the early days was limited to 2D line drawings (such as those made with early AutoCAD versions), but that didn’t last for long.
Moving into the 90s, a genesis toward 3D design started to take place. Programs such as Autodesk Inventor along with early versions of Pro/ENGINEER started to flow into the market. The options and benefits that working within a 3D space have opened up cannot be understated as far as their importance is concerned.
Immense time and cost savings could now be realized thanks to a 3D design process and workflow. Mistakes could now be caught long before prototypes were made. Simulations could mimic complex mechanisms in action and show where failures in the design may have been present. Even the production of 2D manufacturing drawings was streamlined – with the right software all it takes is a few clicks to create a 2D drawing with multiple views. Some even add dimensions as well!
It would be a gross understatement to say that 3D design has only benefitted those that do mechanical design. Almost any industry now has very powerful tools at their disposal to create impressive designs in ways that were never thought possible just a few short decades ago.
Let’s take a brief look at many of the ways that 3D design has helped those across a wide and diverse array of services.
For the most part, all other areas of 3D design could be considered subsets of 3D modeling in general. 3D modeling is the process where mathematically accurate models of physical objects are created within a 3D space. Once generated, these models can be altered and manipulated for just about any purpose, as described in the different sections below.
Imagine being able to design a building and being able to generate realistic virtual. A benefit of 3D architectural modeling is the ability to execute a flythrough.
Once a building or any sort of environment is created virtually using 3D technologies, a designer can actually show on screen what may occur in real life within that space. Designers for manufacturing plants can walk through the plant floor and identify areas where the design or workflow could be improved. Residential architects can have a client move from room to room in their new house without ever laying a single brick. Commercial architects can verify retail floor space designs in real-time, or also show how an office layout may increase overall productivity.
It goes without saying, but 3D design is really good with “things”. Designs for items such as furniture can be quickly “prototyped” virtually on a computer screen. These models also can then be used for rendering purposes whereby complete room, home, and office environments can be viewed with an unbelievable amount of realism.
Mechanical and machine design are two areas that have benefitted greatly from 3D design processes and services. 3D design and modeling as allowed a great deal of “front-loading” when compared to the design processes from the past. Virtual prototypes can be tested and analyzed for proper form, fit, and function before expensive physical prototypes are produced.
Revisions can be made and tested in a matter of minutes. All of the heavy lifting (design-wise) is upfront, resulting in reduced development time, more robust designs, and real cost savings.
As processing power and graphics fidelity have increased, the use of 3D rendering and visualization has become more and more prominent in many design fields. Architects can use photorealistic renderings to show clients how a building environment will look (complete with lush landscaping as well).
Companies such as IKEA use rendered images almost exclusively in their marketing materials and on their website, allowing their customers to let their creative juices flow and build the perfect room – all without making a single purchase upfront. Marketing costs can be greatly reduced as the need for expensive photo sessions have now become a thing of the past.
If you are designing a product and have 3D models created for every part, you can virtually assemble them. This can detect errors such as holes that do not align between parts, and you can also check for interferences that would keep actual parts from being assembled as they should be.
One of the most tedious design processes in the past was the creation of assembly documentation. 3D design gives you an unprecedented level of flexibility in this regard. Software packages such as SolidWorks will let you automatically “explode” an assembly, and you can then take any viewpoint and translate it into a 2D drawing. Bills of materials can be generated on the fly as well by using model description fields (part name, part number, etc.) that are input when the individual 3D part models are created.
3D CAD design is a great asset to any design project. Whether you're developing new consumer products, working on an engineering project, or designing new medical devices, 3D design is a useful tool at many stages of the design process. Early on, 3D models and virtual prototyping is a powerful and cost-effective strategy for concept testing and iterating designs without having to physically produce anything. Later, high-quality 3D renders can be used as marketing tools and to impress investors.
With modern CAD software, the detail and complexity possible with 3D modeling allows designers to do a lot of early development work digitally which used to have to be done through hand-drawn sketching and prototyping. Today, software tools like Autodesk Inventor and SketchUp allow CAD designers to perform stress analysis and other forms of engineering analysis on virtual prototypes before any money has to be spent on creating tangible prototypes. While this doesn't eliminate the need for real prototypes down the road, it allows for designers to fully test out ideas during the conceptual phase of design fearlessly and with as many iterations as needed.
And when it does come time for a real functional prototype, 3D design still has a role to play. With modern 3D printing technologies, rugged functional prototypes can be rapidly manufactured using materials that are similar or identical to those used in final production. Without having to worry about tooling or production runs, additive manufacturing heavily streamlines the prototyping phase. And, of course, you can't take advantage of 3D printing without a good printable 3D design. Many of the designers at Cad Crowd are experienced in creating STL files for 3D printing and understand the manufacturing process.
