How CAD Services Changed Product Design
Using CAD Services May Help with Your Next Product Design
The most fundamental definition of product design is the process by which one efficiently and effectively generates concepts which lead to new products. Product design used to be a process where idea and concept generation happened with sketches on the board, from which industrial designers would then capture the details of the sketch in pencil, pen, or marker. Perhaps the next step would be a mockup of the product out of foam core. This process still occurs today but now there are more avenues by which one can go from ideation to prototype.
What is Computer Aided Design?
Computer Aided Design (CAD) is part of the product design process by which designs can be created as 3D models. Instead of being confined to a 2D sketch, by using CAD software, you can create a 3D model that can be surfaced and shaped to meet your design goals. One of the benefits of this over the traditional method is the potential time and cost savings for design iterations and even prototyping.
Another aspect about CAD models is the ease of rendering. What is rendering? Rendering, also referred to as image synthesis, is the process of taking a 2D or 3D model and generating a photorealistic representation of the model, using a placement of virtual cameras and spotlights. The appropriate 3D rendering software is determined by your starting model, either a 2D sketch or a 3D model. If you have a 2D sketch say from an industrial designer, you can easily take that to the next level with a project rendering in Photoshop. On the other hand, if you have a 3D model, then you can use 3D rendering software such as Photoview 360 or Fusion 360 to create a rendered scene. On the model itself, you can choose color, material property, decals, etc. to get the maximum realistic representation. With a rendered CAD model, your product design workflow becomes much cheaper to iterate both in terms of cost and time.
Does CAD Improve Product Design Workflow?
As mentioned before, your product design workflow of ideate, prototype, iterate, and manufacture can become cheaper both in terms of cost and time. How? The CAD models allow for immediate design feedback in spatial context of manufacturing, especially for more complex assemblies. By using CAD, you can catch any errors in your design before even building a physical prototype.
Another way the product design workflow is improved is through more options in rapid prototyping. By having a 3D model, you are able to quickly process the model for 3D printing, CNC machining, etc. With the quick turnaround times, you will be able to see and implement any design iterations which may be necessary. In turn, once the design is iterated, the product could be rapid prototyped to facilitate the feedback loop until design finalization.
