Detailed tutorial on CAD commands?

As CAD drawing is widely used in engineering, design and other fields, it is crucial to master its basic commands. In this tutorial, PHP editor Youzi will explain the basic CAD commands in detail, from drawing line segments to filling graphics, step by step, and in simple terms. By learning these commands, beginners can quickly master the basics of CAD drawing, while experienced users can also improve drawing efficiency and lay a solid foundation for actual project applications.

1: Commonly used function keys

F1: Get help

F2: Switch between the drawing window and the text window
