Learning CAD can be both challenging and rewarding. Here are some tips that helped me along the way:
1. Get familiar with at least 20–40 commonly used commands, and understand what each parameter does. It’s important to know not just how to use them, but also when and why.
2. Learn the shortcuts for frequently used commands. This will save you time and make your workflow smoother. Don’t be afraid to experiment and see how different commands work together.
3. Practice while learning. I’ve been using CAD for two years now, and even after all this time, I still come across commands I don’t fully understand. When that happens, I look up tutorials or study example drawings to improve my skills.
4. Follow a structured approach. Work through textbooks step by step, and always take time to review and reflect on what you’ve learned. Repetition is key to mastering any skill.
5. Understand how to use layers effectively. Layers help organize your drawing and make it easier to manage complex projects.
6. Keep notes as you go. Writing things down helps reinforce your memory. Start from the basics, and don’t skip over anything. Even small details can have a big impact in the long run.
7. Embrace challenges. Stress can actually be a great motivator if you learn to use it wisely. Every difficulty you overcome makes you a better designer.
Here is a list of common CAD shortcuts that can speed up your workflow:
