Fonts define the shapes of the text characters that make up each character set. A single font can be used by more than one style. Use the FileName property to set the font file for the text style. You can assign TrueType or AutoCAD-compiled SHX fonts to a text style.
The following example gets the current font values using the Font property for the active text style and then changes the typeface for the font to “PlayBill.” To see the effects of changing the typeface, add some multiline or single-line text to your current drawing before running the example. Note that, if you don't have the PlayBill font on your system, you need to substitute a font you do have in order for this example to work.
