Character Descriptor Format
The format for adding text characters in a linetype description is as follows:
["text",textstylename,scale,rotation,xoffset,yoffset]
This format is added as a descriptor to a simple linetype. For example, a
linetype called HOT_WATER_SUPPLY is defined as
*HOT_WATER_SUPPLY,---- HW ---- HW ---- HW ---- HW ---- HW
----
A,.5,-.2,["HW",STANDARD,S=.1,U=0.0,X=-0.1,Y=-.05],-.2
This indicates a repeating pattern starting with a dash 0.5 drawing units long,
a space 0.2 drawing units long, the characters HW with some scale and
placement parameters, and another space 0.2 drawing units long. The text
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.
text The characters to be used in the linetype.
text style name The name of the text style to be used. If no text style is
specified, AutoCAD uses the currently defined style.
