About Line Fonts
You can create and customize the fonts used for your two-dimensional draft lines. A line font is a pattern of dashes and spaces that are proportionate within the specified length. For example, 5 dashes and 5 spaces with a pattern length of 1 inch results in two dashes and spaces for a 2-inch line in the drawing. The same pattern definition with a 1/4-inch pattern length results in 8 dashes and spaces for a 2-inch line in the drawing. You can have a maximum of 16 dash-space combinations in a line font file.
User-defined line font files, <fontname>.lsl, must reside in your local directory for you to be able to use them. When you retrieve a drawing, and the system cannot find a line font file, it displays any line that has been set with that style as solid and notifies you that it has not loaded a font file.
If you have specified auxiliary font files in the Detail options file (this occurs automatically when you create the font when that drawing is active), it identifies the font files that it could not find.
 
You can set a default length for the line font using the line_style_length Detail option.
You can import and export IGES line font defintions using theiges_in_dwg_line_font (Import) and iges_out_dwg_line_font (Export) configuration options.
