Does anyone know all the shortcut commands for CAD?

I think it is better to buy a book. It is very convenient to keep at hand. The book is not very expensive and is easy to buy. You can also borrow it from your colleagues and have a look.

The definition of shortcut commands has been comprehensively mentioned. All shortcut commands defined by AutoCAD are saved in the ACAD.PGP file. ACAD.PGP is a plain text file that users can edit using an ASCII text editor (such as EDIT under DOS) or directly using the Notepad in the WINDOWS attachment. Users can add some Auto CAD command shortcuts to the file themselves. Typically, shortcut commands use one or two letters that are easy to remember and use them instead of the full command name. The shortcut command definition format is as follows: Shortcut command name, * The full name of the command is as follows: CO, * COPY means after typing the shortcut command, type a comma and the full name of the command replaced by the shortcut command. AutoCAD commands must be prefixed with an asterisk. (1) Letter class 1.

Now most people define themselves. * By using the left-hand keys, this can greatly improve the drawing speed. If you are interested, you can try it yourself.

After using CAD for a long time, you will naturally understand that practice makes perfect.

If you define it yourself, it will be convenient for you to use it, but if you suddenly use a colleague's computer, it will be awkward.

There are a lot of them in the forum. You can find them by searching them, or you can search them on Baidu.

Just a few commonly used ones will do. I remember so many there.
