To understand CAD software, we should understand the function, interface and operating tools of the software. It is a visual drawing software, and many commands and operations can be realized through menu options and tool buttons. Beginners can basically operate when learning to use layers and cad blocks.
Cad drawing is a powerful software, which is also used in many industries and fields. It uses computers and their graphics devices to help designers complete the design work. Cad drawing has undergone many changes. Initially, this field was mainly used to make similar hand-drawn drawings. Nowadays, cad is not only used for drawing and displaying, but also begins to enter a more "intelligent" part of designers' professional knowledge.
It takes at least one month to learn the training course of cad drawing, which also depends on the individual's understanding and knowledge acceptance, and some of them take more than three months to master. Cad is not only to learn drawing, but also to understand design and process knowledge.
