cad的快捷键被人改了 怎么该回默认

怎么讲CAD快捷键还原为默认模式？

工具\材料
CAD软件 电脑
方法如下
1、首先在电脑上打开开始菜单，点击“所有程序”。

2、接着点击“Autodesk”选项。

3、接着鼠标单击“将设置重置为默认值”选项。

4、打开CAD软件，点击左上角的选项。

5、接着点击“选项”。

6、最后点击“配置”“重置”选项即可。

默认改不了了，除非有快捷间备份，替换已被修改的快捷键。或者别人改的你什么键，我去那个地方修改过来也行。
Tools(工具)，然后Customize（倒数第二个），然后Edit
Custom
Files（最后一个），最后Program
Parameters(acad.pgp)
或者，看不懂的话。直接密我。

打开cad，点工具---自定义---编辑自定义文件---程序参数
进去后摁ctrl+A（全选），删除
把下面我引号里的贴进去，不包括引号

; AutoCAD Program Parameters File For AutoCAD 2004
; External Command and Command Alias Definitions

; Copyright (C) 1997-2002 by Autodesk, Inc.

; Each time you open a new or existing drawing, AutoCAD searches
; the support path and reads the first acad.pgp file that it finds.

; -- External Commands --
; While AutoCAD is running, you can invoke other programs or utilities
; such Windows system commands, utilities, and applications.
; You define external commands by specifying a command name to be used
; from the AutoCAD command prompt and an executable command string
; that is passed to the operating system.

; -- Command Aliases --
; You can abbreviate frequently used AutoCAD commands by defining
; aliases for them in the command alias section of acad.pgp.
; You can create a command alias for any AutoCAD command,
; device driver command, or external command.

; Recommendation: back up this file before editing it.

; External command format:
; <Command name>,[<DOS request>],<Bit flag>,[*]<Prompt>,

; The bits of the bit flag have the following meanings:
; Bit 1: if set, don't wait for the application to finish
; Bit 2: if set, run the application minimized
; Bit 4: if set, run the application "hidden"
; Bit 8: if set, put the argument string in quotes
;
; Fill the "bit flag" field with the sum of the desired bits.
; Bits 2 and 4 are mutually exclusive; if both are specified, only
; the 2 bit is used. The most useful values are likely to be 0
; (start the application and wait for it to finish), 1 (start the
; application and don't wait), 3 (minimize and don't wait), and 5
; (hide and don't wait). Values of 2 and 4 should normally be avoided,
; as they make AutoCAD unavailable until the application has completed.
;
; Bit 8 allows commands like DEL to work properly with filenames that
; have spaces such as "long filename.dwg". Note that this will interfere
; with passing space delimited lists of file names to these same commands.
; If you prefer multiplefile support to using long file names, turn off
; the "8" bit in those commands.

; Examples of external commands for command windows

EXPLORER, START EXPLORER, 1,,
NOTEPAD, START NOTEPAD, 1,*要列出的文件: ,
PBRUSH, START PBRUSH, 1,,

; Command alias format:
; <Alias>,*<Full command name>

; The following are guidelines for creating new command aliases.
; 1. An alias should reduce a command by at least two characters.
; Commands with a control key equivalent, status bar button,
; or function key do not require a command alias.
; Examples: Control N, O, P, and S for New, Open, Print, Save.
; 2. Try the first character of the command, then try the first two,
; then the first three.
; 3. Once an alias is defined, add suffixes for related aliases:
; Examples: R for Redraw, RA for Redrawall, L for Line, LT for
; Linetype.
; 4. Use a hyphen to differentiate between command line and dialog
; box commands.
; Example: B for Block, -B for -Block.
;
; Exceptions to the rules include AA for Area, T for Mtext, X for Explode.

; -- Sample aliases for AutoCAD commands --
; These examples include most frequently used commands.

默认改不了了，除非有快捷间备份，替换已被修改的快捷键。或者别人改的你什么键，我去那个地方修改过来也行。
Tools(工具)，然后Customize（倒数第二个），然后Edit Custom Files（最后一个），最后Program Parameters(acad.pgp)
或者，看不懂的话。直接密我。

修改快捷键的步骤

1、依次单击“工具”菜单 »“自定义”»“界面”。
2、在“自定义用户界面”编辑器的“自定义”选项卡上，单击“键盘快捷键”旁边的加号 (+) 将其展开。
3、单击“快捷键”旁边的加号 (+) 将其展开。
4、单击某个快捷键。
5、“特性”窗格中将会显示选定快捷键的特性。

重新安装一下就可以了!
