characters come from the text font assigned to the STANDARD text style at a
scale of 0.1, an upright rotation of 0 degrees, an X offset of -0.1, and a Y offset
of -0.05. This pattern continues for the length of the line, ending with a dash
0.5 drawing units long. The linetype would be displayed as shown below.


Notice that the total upstroke length is 0.2 + 0.2 = 0.4 and that the text origin
is offset -.01 units in the X direction from the end of the first upstroke. An
equivalent linetype would be


*HOT_WATER_SUPPLY,----HW ----HW ----HW ----HW ----HW ----
A,.5,-.1,["HW",STANDARD,S=.1,U=0.0,X=0.0,Y=-.05],-.3

The total upstroke is still 0.1 + 0.3 = 0.4, but the text origin is not offset in the
X direction.


Additional information about each field in the character descriptor follows.
The values to be used are signed decimal numbers such as 1, -17, and 0.01.


textThe characters to be used in the linetype.


text style nameThe name of the text style to be used. If no text style is
specified, AutoCAD LT uses the currently defined style.


scaleS=value. The scale factor to be used for the text style relative to the scale
of the linetype. The height of the text style is multiplied by the scale factor.
If the height is 0, the value for S=value alone is used as the height.


rotationU=value, R=value, or A=value. U= specifies upright or easy-to-read
text. R= specifies relative or tangential rotation with respect to the line. A=
specifies absolute rotation of the text with respect to the origin; that is, all
text has the same rotation regardless of its position relative to the line. The
value can be appended with a d for degrees (degrees is the default value), r for
radians, or g for grads. If rotation is omitted, 0 relative rotation is used.


Rotation is centered between the baseline and the nominal cap height.
