Text Font Descriptions
Text fonts must include a special shape number 0 that conveys information
about the font itself.
AutoCAD is packaged with numerous text fonts. You can use the STYLE
command to apply expansion, compression, or obliquing to any of these fonts,
thereby tailoring the characters to your needs. You can draw text of any height,
at any baseline angle, and with either horizontal or vertical orientation using
these fonts.
AutoCAD text fonts are files of shape definitions with shape numbers
corresponding to the ASCII code for each character. Codes 1 through 31 are
for control characters, only one of which is used in AutoCAD text fonts:
10 (LF) The line feed (LF) must drop down one line without drawing. This is
used for repeated TEXT commands, to place succeeding lines below the first
one.
*10,5,lf
2,8,(0,-10),0
You can modify the spacing of lines by adjusting the downward movement
specified by the LF shape definition.
Text fonts must include a special shape number 0 that conveys information
about the font itself. The format has the following syntax:
*0,4,font-name
above,below,modes,0
