CAD命令的定制与开发

CAD命令的定制与开发

通过CAD上的“工具——自定义——编辑自定义文件——程序参数（acad.pgp）”可以打开acad.pgp文件，该文件就是CAD命令定制文件，如下图所示：

CAD的命令文件存放在C:/Documents and Settings/xzy/Application Data/Autodesk/AutoCAD 2004/R16.0/chs/Support下面，如下图所示：

下面来看一下该文件的内部结构：
;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.

; 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.

该文件中，凡是“；”后面的都是注释，删除对结果没有任何影响，但是为了方便识度，还是保留为好。
其中，以“VIEWPORTS, *VPORTS”为例，前面的VIEWPORTS是要求输入的文字命令，后面的VPORTS是CAD的内部命令，通过VIEWPORTS和VPORTS命令进行一个连接。当然你可以随便更改前面的VIEWPORTS，只要和已有的命令不重复，但是后面的一定不能更改。譬如你可以更改为“V1,*VPORTS”，而且输入V1命令和输入VPORTS命令的结果是一样的。根据更改ACAD.PGP文件，你可以编写适合自己特点的命令文件。同时，当你安装其他CAD的开发软件后，如南方测绘等，它会更改系统原来的命令，这适合你只需要将ACAD.PGP文件恢复就可以了。
