Maps AutoCAD fonts to system TrueType fonts.
SmartSketch supports system TrueType fonts. AutoCAD-compiled shape fonts (.shx) and
postscript binary fonts (.pfb) are not supported. Many of the standard AutoCAD fonts
are pre-mapped to their most equivalent TrueType fonts. If a font is not mapped,
it defaults to the font specified in the first entry in the font mapping list.
