Specifying an Alternate FontIf your drawing specifies a font that is not currently on your system, the font designated as your alternate font is automatically substituted. By default, the simplex.shx file is used. If you want to specify a different font, enter the alternate font file name by changing the FONTALT system variable. If you use a text style that uses an Asian Big Font, you can map it to another font using the FONTALT system variable. This system variable uses a default font file pair: txt.shx and bigfont.shx.In previous releases, you could display PostScript ® fonts in the drawing. Because later releases cannot display PostScript fonts, Autodesk has supplied TrueType font equivalents. These PostScript fonts are mapped to the equivalent TrueType fonts in a font mapping file.
Additionally, when a TrueType font is not available, you can specify a different TrueType font, making sure that the fonts are similar to avoid text length or wrapping problems.If the default font does not support the characters you enter using the In-Place Text Editor, an alternative font is substituted.CIF or MIF codes entered with the In-Place Text Editor are now automatically converted to display the actual characters. Editing the Font Mapping FileA font mapping file is a list of text fonts and their substitutes. If a text font used in a drawing cannot be located, another text font is substituted for the missing font using a font mapping file.Each line in the font mapping file contains the name of a font file (with no file extension or path) followed by a semicolon (;) and the name of the substitute font file. The substitute file name includes a file extension such as.ttf.A font mapping file is an ordinary ASCII text file with a.
Fmp extension. You can change the font assignments in a font mapping file using any ASCII text editor.For example, you could use the following entry in a font map file to specify that the timesnr.pfb font file be substituted with the times.ttf font file:timesnr;times.ttfThe following table shows the font substitution rules used if a font file cannot be located when a drawing is opened.
