Introduction
In addition to the four built-in line types, DataCAD supports up to
175 user-defined line types. The built-in lines are Solid, Dotted, Dashed
and Dot-Dash. You cannot change or remove the definitions of these 4
lines.
DataCAD ships with a number of custom line types. You can edit, remove
or rearrange the order of these lines. The custom lines are stored in
a file named DCADWIN.LIN in your support subdirectory (NOTE: for this
tutorial we will assume DataCAD for Windows standard filenames. DOS
filenames are similar but lack the WIN in the name for example DCAD.LIN.)
Each individual line type is listed in this one file. If the DCADWIN.LIN
file is not in your support subdirectory you will only see the four
built-in line types in the line type menu. If DataCAD finds more than
50 user-defined line types in this file it will give an error message
at startup but will otherwise work fine.
The DCADWIN.LIN file is an ASCII text file and can be edited by any
editor that supports ASCII text. While you can use a word processor
such as Microsoft word to edit these files it is best to use an editor
designed specifically for editing ASCII text files. A word processor
will add formatting and other items that will render your files unreadable
by DataCAD. If you don't have a favorite text editor try Notepad or
Edit, both of which are available with all flavors of Windows, or try
one of the editors we recommend.
Remember two things when writing line types. First DataCAD will ignore
all "whitespace" in the LIN file, so feel free to adjust the
space between your text so that it is legible to you. Next remember
that DataCAD loads line types when it is started so if you are editing
your DCADWIN.LIN file and don't see your changes on screen, close DataCAD
and restart it to reload the line types.
