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
The above value specifies the number of vector lengths above the baseline
that the uppercase letters extend, and below indicates how far the lowercase
letters descend below the baseline. The baseline is similar in concept to the
lines on writing paper. These values define the basic character size and are
used as scale factors for the height specified in the TEXT command.
The modes byte should be 0 for a horizontally oriented font and 2 for a
dual-orientation (horizontal or vertical) font. The special 00E (14) command
code is honored only when modes is set to 2.
The standard fonts supplied with AutoCAD include a few additional characters
required for the AutoCAD dimensioning feature.
%%d Degree symbol (°)
%%p Plus/minus tolerance symbol ( )
%%c Circle diameter dimensioning symbol
You can use these and the %%nnn control sequences, as described under TEXT
in the Command Reference.
NOTE AutoCAD draws text characters by their ASCII codes (shape numbers) and
not by name. To save memory, specify the shape name portion of each text shape
definition in lowercase as shown in the following example. (Lowercase names are
not saved in memory.)
*65,11,uca
024,043,04d,02c,2,047,1,040,2,02e,0
Because the shape name uca contains lowercase letters, AutoCAD does not
save the name in memory. However, you can use the name for reference when
editing the font definition file. In this example, uca stands for uppercase A.
