# Practice Makes Perfect: Mastering CAD Through Consistent Effort

By M.A. Buth

In any discipline, whether it’s playing the piano, playing tennis, programming, or CAD design, practice is the key to becoming proficient and efficient. However, the demands of a busy professional life often leave little room for dedicated practice. In times of low workload, practicing on command can create additional stress. My advice: Practice outside of professional constraints, on your own terms and schedule, but do it with enjoyment!

1. Accept That You Can’t Know Everything and Specialize

CAD is a vast field. Just as an ophthalmologist can't know everything about dermatology but should have a good understanding of it, you can’t master every aspect of CAD in a single lifetime. Accept that some colleagues might be faster and better at designing piping or gears, while you might be an expert in designing PCBs. You can shift your area of expertise over your career, but don’t try to master everything at once. The amount of knowledge required is simply too extensive.

2. Expand Your Expertise in a Relaxed Manner

CAD is almost always just one part of the development of an entire project. There are times when you can't focus much on CAD because you need to test prototypes, write reports, or perform other tasks that don’t involve CAD. This is a good opportunity to deepen your specialized knowledge or practice rarely used aspects of the CAD system that could be useful. Design things in your free time that meet these requirements but also have a practical use, such as toys for children, household items, or parts for your workshop, car, or quadcopter.

The big advantage here is that you can do all this without a deadline or professional time pressure. If you encounter problems, you can find your own solution without company constraints. Visit relevant forums and communities, describe your problem, learn new things, and determine the amount and speed yourself. The journey is the reward.

3. Use a 3D Printer to Validate Your Virtual Designs

Everything looks perfect on the screen, but when the CAD-designed object is in your hands, you might find that parts are mechanically unstable or don’t fit. FDM 3D printers have become so affordable and easy to use that you should invest $200-$300 to bring your creations to life. The printer doesn't need to be exceptionally fast or complex. On the contrary, use a reliable and relatively simple device so you can focus on CAD without investing much energy into learning complex additive manufacturing processes. For prototyping, PLA or PETG material is sufficient. This class of 3D printers is inexpensive and requires little effort and knowledge regarding operating parameters. Use a well-known, established device rather than the latest hyped super 3D printer. They look great on paper and promise a lot but often have "teething problems."

4. Utilize AI!

Forums and communities are great for finding help with a problem. Sometimes, however, it takes a long time to get a useful answer, which can be hours or even days. In the meantime, you can ask an AI like OpenAI's ChatGPT about your CAD problem. AIs have peculiar properties when it comes to the usefulness and accuracy of answers. You almost always get an answer, but it doesn't have to be correct. Nonetheless, AI can help you find a solution. It’s very quick and you can ask follow-up questions immediately.

I hope this brief essay has encouraged you to try new things to deepen your CAD knowledge!
