Matching is a crucial part of learning CAD. Here are some key points to help you improve your skills:
1. Master at least 20–40 commonly used commands and understand their parameters thoroughly.
2. Learn the shortcuts for frequently used commands, which will significantly speed up your workflow.
3. Practice while learning. I've been using CAD for two years, and even now, I still refer back to examples or data to reinforce my understanding.
4. Follow a structured approach by going through textbooks step by step. Repeating lessons and reviewing them helps solidify your knowledge.
5. Understand how to use layers effectively, as they are essential for organizing drawings.
6. Take notes while practicing. Start from scratch if needed, and don't rush. Learning takes time, but it's rewarding when you see progress.
7. Embrace challenges and stress as motivation. They push you to learn more and improve faster.
Here is a list of common CAD shortcuts that can greatly enhance your efficiency:
