CAD programs are among the most powerful tools available to modern engineers, architects, and inventors. They have made it easier to design and test new products than ever before, and that has revolutionized many industries. They embody many of the best features of technological progress, and there is a lot to learn about technology from examining them.
Technology Begets Technology
CAD modeling is not useful because it makes our lives better on its own, but because it helps us to make things that make our lives better. That reveals one of the secrets of technology that few people grasp. Technology creates tools that allow us to make better tools, and the most influential technologies are those that lead to later developments. Even an invention that seems useless on its own can be valuable when it is necessary to create other things. CAD has improved dozens of industries, and it has even made it easier for astronauts to operate in space. Who knows what else it will help us to do?
It Needs Human Guidance
CAD is a tool, but tools only function with human hands to guide them. It makes it easier for humans to develop new products, but it can’t do that without a human who understands their goal and the principles of engineering. This simple fact teaches us that no matter how far technology has come and how many tasks it can perform, we still haven’t been able to design a machine that is as creative as a human.
It Takes Practice
No program can serve as a substitute for skill. CAD modeling can make the design process much easier, but that doesn’t mean that anyone can do it without training. CAD is a skill in its own right that people need to learn in order to rely on it. It’s simpler and quicker to learn than many other skills, but workers still need to practice if they want to get good at it.Technology changes the skills that people need, but it doesn’t eliminate the need for skills.
It Reduces Costs
Technology revolutionizes industries because it makes things cheaper. In the case of CAD, it does that by saving time and reducing the need for expensive prototypes. In other cases, it can do that by making precision work easy or by performing unskilled labor. This is an important lesson, because it illustrates the amount of social and industrial change that can come from simply reducing costs.
It Changes Industries
No industry can face the technological revolution without changing. CAD changed the way that designers work and it made things cheap, and that changed the entire world of design. All technologies have that power, and it’s impossible to predict those changes far in advance. Workers in the technological world must learn to expect change and need to be ready to adapt to it.
