Learning CAD requires the following aspects:

Learning CAD (computer-aided design) requires the following elements:

1. Computer hardware: A high-performance computer is required to run CAD software and meet the requirements of CAD Minimum system requirements for the software. Computers are usually required to have a faster processor, large memory, and a high-performance graphics card. In addition, a high-resolution monitor is required to display the CAD drawing.

2. CAD software: Choosing the right CAD software is the key to learning CAD. There are many different CAD software options on the market, such as AutoCAD, SolidWorks, Catia, etc. Choose the appropriate CAD software based on your needs and learning goals.

3. Learning materials and tutorials: Obtain some learning materials such as CAD books, online tutorials, and video tutorials to help understand the basic functions and operation methods of CAD software. These materials can be obtained from bookstores, online education platforms, and official websites of CAD software manufacturers.

4. Basic drawing concepts and skills: Before learning CAD, you need to have some basic drawing concepts and skills. Understanding basic concepts such as coordinate systems, dimensional specifications, projection methods, and fixation points, and possessing certain hand-drawing skills will help you learn and apply CAD software.

5. Practice and projects: In addition to theoretical knowledge, practice is the key to learning CAD. By completing some practice projects and practical design tasks, you can improve your proficiency in CAD software and apply what you have learned to real-life situations.

Example:

If you choose to learn AutoCAD, you need to prepare the following materials:

1. (1) A computer with high configuration that meets the requirements of AutoCAD.
2. (2) Install AutoCAD software, you can purchase or download the trial version from the official website.
3. (3) Materials and tutorials: Purchase some textbooks or online learning platform courses, such as AutoCAD official tutorials, books or online video tutorials.
4. (4) Learn basic drawing concepts and skills: Learn basic concepts such as coordinate systems, dimension specifications, drawing commands, etc., and practice hand drawing.
5. (5) Practice and projects: Start with simple practice projects and gradually challenge more complex design tasks, such as floor plan drawing, architectural design, mechanical design, etc.

Summary:
 Learning CAD requires computer hardware, CAD software, learning materials and tutorials, basic drawing concepts and skills, and practices and projects. By preparing these things, you can start learning and applying CAD software to improve your capabilities in the field of computer-aided design
