Naming rules of CAD shortcut commands and commonly used shortcut keys

Thread Content

Naming rules of CAD shortcut commands and commonly used shortcut keys AutoCAD is currently the preferred design software for engineering designers around the world. Ease of learning and accuracy are two important reasons for AutoCAD's success. There are many commands provided by AutoCAD, but only 20% of them are most commonly used when drawing. When using the keyboard to input commands, some commonly used commands are long, such as BHATCH (fill) and EXPLODE (explode). The number of keystrokes required during input is large, which affects the drawing speed. Although AutoCAD provides two complete input methods, menu and toolbar, to increase the drawing speed, you can only master the fast command input method provided by AutoCAD. While conducting AutoCAD design, training and teaching research, the author has accumulated some experience in the use and management of shortcut commands. I have now summarized them for your reference when using AutoCAD 2000. 1. Overview: The so-called shortcut command is a shortcut defined by AutoCAD to increase the drawing speed. It uses one or a few simple letters to replace commonly used commands, so that we do not have to remember many long commands, nor do we have to search for them on menus and toolbars to execute a command. All defined shortcut commands are saved in the ACAD.PGP file in the SUPPORT subdirectory of the AutoCAD installation directory. We can define our own commonly used shortcut commands by modifying the contents of the file. Every time we create or open an AutoCAD drawing file, CAD itself will automatically search the SUPPORT path in the installation directory, find and read the ACAD.PGP file. When AutoCAD is running, we can use the command line to complete an operation using the shortcut commands defined in the ACAD.PGP file. For example, if we want to draw a straight line, we only need to enter the letter "L" in the command line. China 3S Bar 3s8.cn 2. Naming rules of shortcut commands 1. A shortcut command is usually the first or first two letters of the English word of the command, and some are the first three letters. For example, the shortcut command for Line is "L” ； The shortcut command for copying (COpy) is "COpy"” ； The shortcut command for line scale (LTScale) is "LTS". During use, try to use the first letter of the command. If that doesn't work, use the first two letters, or at most the first three letters. That is to say, AutoCAD's shortcut commands generally do not exceed three letters. If a command does not work with the first three letters, you can only enter the complete command. 2. Another type of shortcut command is usually composed of "Ctrl key + a letter", or is defined by the function keys F1~F8. For example, Ctrl key + "N", Ctrl key + "O", Ctrl key + "S", Ctrl key + "P" respectively represent creating, opening, saving, and printing files. ； F3 stands for "Object Snap". 3. If the first letters of some commands are the same, then the commonly used commands will be represented by the first letter, and other commands can be represented by the first two or three letters. For example, "R" means Redraw, "RA" means Redall ； For example, "L" represents Line, "LT" represents LineType, and "LTS" represents LTScale. 4. We need to remember some exceptions. For example, "modify text" (DDEDIT) is not "DD", but "ED"” ； There are also "AA" for Area, "T" for Mtext, and "X" for Explode. China 3S Bar 3s8.cn 3. 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.
