Custom Linetypes

AutoCAD LT® provides a library of standard linetypes in the acadlt.lin and acadltiso.lin files.
You can use the linetypes as they are, modify them, or create your own custom linetypes.

Overview of Linetype Definitions

Linetypes are defined in one or more linetype definition files that have a .lin

file extension.

The linetype name and definition determine the particular dash-dot sequence,

the relative lengths of dashes and blank spaces, and the characteristics of any

included text or shapes. You can use any of the standard linetypes that AutoCAD

LT provides, or you can create your own linetypes.

examples of linetypes

A LIN file can contain definitions of many simple and complex linetypes. You

can add new linetypes to an existing LIN file, or you can create your own LIN

file. To create or modify linetype definitions, edit the LIN file using a text editor

or word processor or use LINETYPE at the command prompt.

When you create a linetype, you must load the linetype before you can use it.

The LIN files included in AutoCAD LT are acadlt.lin and acadltiso.lin. You can

display or print these text files to better understand how to construct linetypes.
