What is CAD Design?

Firstly let’s ask the question what is CAD Design?

CAD is an acronym that stands for Computer Aided Design. In short, is the process of creating design outcomes using the computer, rather than a pencil and paper. Its usage varies from two-dimensional architectural drawings, to full scale three-dimensional realistic computer models. In short, CAD is used in all disciplines of design from consumer products through to large scale architectural work.

Specialist computer software is used for CAD modelling, and there are a lot to choose from depending on designers specialities and requirements. Blue Dots Design uses Fusion 360 for computer modelling, which is used by over 1.2 million individuals, and large companies such as Yamaha and Logitec.*

In product design terms, it is the stage of the design cycle that moves a concept from a hand drawing or sketch into a more refined computer model. Creating a 3D model of the proposed product design enables designers to resolve areas of the product that otherwise will have been overlooked on paper. Is also helps clients to view the proposed design in a virtual reality space in 3D form on screen.

With 3D CAD, designers can share, review, simulate, and modify designs easily (most of the time!) This allows a smooth transition and work flow from the design development stage to a more refined product.

Computer rendering

3D CAD can also be used to create photorealistic renderings. These renderings can be used for promotional videos, fundraising and advertising. In fact, a lot of large brands use computer renderings on websites instead of photographs because the lighting and material textures are much easier to edit than the real products.

From CAD to prototype

Computer generated 3D CAD models are also essential to produce a prototype of the desired design. They provide sizes, material thicknesses and joining mechanisms that are needed to produce a realistic prototype.

A 3D CAD model is usually the exact same size and shape that the real world product would be, allowing the prototype production to happen easily. This helps communicate scale, form, and feel to clients quickly and in a cost effective manner.
