Linetype is a visual property assigned to geometric objects. Linetypes can be a pattern of dashes, dots, text, and symbols, or unbroken and continuous.
Command line enter: LINETYPE or LT

Load Linetypes #
For linetypes that you use frequently, you can load them in a template drawing. Then when you create drawings from the template, the linetypes are already loaded.

Linetypes are defined in a linetype definition (LIN) file. When you load a linetype, you select the linetype definition file and a specific linetype from within that file.
Global Scale Factor #
The global scale factor affects the appearance of all the linetypes in the drawing. You can set the global scale factor by changing the LTSCALE system variable at the Command prompt or with the Linetype Manager. The default global scale factor is 1.0. The smaller the scale factor, the more repetitions and the smaller the spacing in each linetype pattern.

If you change the global scale factor, the appearance of all the linetypes in the drawing change.
