The capability to customize AutoCAD and AutoCAD LT is based on
the fact that most of the support files are text files that you can edit
yourself. The menu and tool palettes are in XML files that you customize
using the Customize User Interface dialog box and the
Customize dialog box.
| sample.cus |
Custom dictionary file. You can add words to the custom dictionary for use with the SPELL command. |
| acad.pgp |
Program parameters file. This file is generally used to create keyboard shortcuts (called aliases) for commands. |
| acad.cui |
Customization file. You modify this file using the Customize User Interface dialog box. |
| acad.mnl |
AutoLISP routines used by AutoCAD's main menu. If you create your own menus, you can have an MNL file with the same name as your menu for AutoLISP routines. |
| acad2007.cfg |
Configuration file for storing digitizer and other settings. Usually, you should use the Options dialog box to make these selections, instead of manually editing this file. |
| acad.dcl |
Dialog Control Language (DCL) file. This file describes dialog boxes. You usually don't edit this file, but you can write your own DCL files to create dialog boxes. |
| acad.lin and acadiso.lin |
Linetype definition file. You can also create your own linetype definition (LIN) files or add your own definitions to acad.lin. |
| acad.lsp and acaddoc.lsp |
AutoCAD's AutoLISP files. You create these files from scratch. You can edit or add to these files to automatically load AutoLISP routines. |
| acad.mln |
AutoCAD's multiline library file. AutoCAD only. |
| acad.pat and acadiso.pat |
AutoCAD's hatch pattern file. You can also create your own. |
| *.pc3 |
Plot configuration files. You can also create your own. A PC3 file contains all configuration settings for a plotter. This is not a text file; you customize it using a dialog box. |
| acad.fmp |
Font mapping file. Use this file to specify substitute fonts, whether or not the original fonts are available on your system. |
| acad.psf |
PostScript support file. It is used for the PSOUT and PSFILL commands. |
| acad.slb |
Slide library file, used for hatch pattern examples in menus. You can use this file or create your own slide libraries. This is not a text file; |
| *.scr |
A script file that you create and name. Script files are
macros of commands and options that run automatically. |
| *.shp |
A shape file that you create and name. Shape files usually hold fonts, but can hold other shapes as well. A shape file is then compiled into a file with an SHX extension for more efficient use. |
| acad.rx |
A list of ARX (an interface for programming AutoCAD)
applications that load automatically. |
| mtextmap.ini |
Font mapping for the appearance of text in the MTEXT editor. |
| acad.unt |
A file that defines every conceivable type of unit. |
