At its most simple level, the engineering discipline is about exploration and iteration—which are the two principles computer-aided design (CAD) is built upon. CAD has come a long way from the time when its primary use was to document finalized drawings. Where once CAD was a final step in the design process—today, it is a valuable first step. If you are not using CAD from the initial design stage, you are missing out on some of the most helpful aspects of the program.
Design Iterations
When it comes to designing, iterations are both helpful and inevitable. How often does our first design actually become the final design? Many inventors have an idea of what they want their final product to look like, but often times this initial design idea has to be modified to account for usability and manufacturing. With 3D CAD you can explore a seemingly endless array of design options without the need of “starting from scratch” for each iteration.
Explore the Design Possibilities
Coming up with the best possible design of a product is a trial-and-error process. You try one approach, when it fails, you try a different approach, and so forth until you come up with the best possible design. The features many CAD programs have today allow you to quickly navigate this trial and error stage while honing in on a final design that will meet all needed specifications.
By using a 3D digital design process, we are able to create designs and validate them with up to 95% certainty that they will work before even building a prototype. -Collin Kobayashi, President & Chief 3D Officer of 3D Innovations
Two valuable CAD features are parametric design and direct modeling, as detailed below by Autodesk:
“Parametric modeling allows users to build intelligent and reactive sequences of geometries in which engineers gradually capture their design intent. In this case, intelligent and reactive means the capability to create geometric objects that react to each other and behave as they would in the real world, rather than just on a computer. So as you iterate and change your model, the software’s parametric modeling capability maintains consistent relationships between elements.”
“With direct modeling, you manipulate a model’s geometry by pushing, pulling or twisting it. This allows you to focus initially on creating geometry rather than thinking about building features, constraints and design intent into models. You add features and constraints when editing the model, so you don’t have to edit the interim model stages.”
3D CAD lets you get a real sense for the product you are developing. Not only does it speed up product development, but it brings ideas to life at the fraction of the cost of what it takes to prototype. By shifting CAD to the start of the design process, you are opening the door to an array of design possibilities.
