You can designate fonts to be substituted for other fonts or as defaults when AutoCAD cannot find a font specified in a drawing.
The fonts used for the text in your drawing are determined by the text style and, for mtext, by individual font formats applied to sections of text.
You can use font mapping tables to ensure that your drawing uses only certain fonts, or to convert the fonts you used to other fonts. You can use these font mapping tables to enforce corporate font standards, or to facilitate offline printing. AutoCAD comes with a default font mapping table. You can edit this file using any ASCII text editor. You also can specify a different font mapping table file by using the FontFileMap property on the Preferences object.
For more information about font mapping tables and substituting fonts, see ‚ÄúSubstitute Fonts‚ÄĚ in the User's Guide.
