A linetype defines a line's characteristics. A line (and many other entities) can consist of combinations of dashes, dots, spaces and symbols defined by a linetype file. gCADPlus allows users to load AutoCAD linetype files. These files are simple text files have the extension .lin.

Loading linetypes

When you start a new drawing, a comprehensive set of linetype patterns is usually pre-loaded as shown in the figure below (from the Imperial version of gCADPlus).

New linetypes are available by clicking on the new icon and browsing to the location of a different .lin file.  The LINETYPE command can also be typed from the keyboard to load a different linetype file.

Linetype scale

It is often the case that even though and entity has a linetype style associated with it, the pattern does not show. All you may see is a continuous line even though the pattern may be (say) dots. This is because the linetype scale is not set appropriately. It is not possible for us to second guess the size of your design. If the linetype pattern does not show, experiment with different values for the linetype scale.

New entity linetype

New entities are added to a drawing using the current linetype style. Change the linetype style via the Properties box or by the linetype icon on toolbar 1.
 
When you create a new drawing it already has linetypes named "ByLayer", "ByBlock", and, "Continuous" irrespective of the status of the .lin file. These styles cannot be removed.
 

AutoCAD linetype files

gCADPlus allows the use of AutoCAD .lin files. These can be loaded using the 'add from file' option in this dialog box.
 

Basic linetype files

By default, the metric version of gCADplus should load the file acadiso.lin and the Imperial version acad.lin. Both linetype files should be available to you no matter which version you use.

The figure below shows the linetypes available when a linetype file called acadiso.lin is loaded.

The image below shows an example where a polyline, with a dot pattern associated with it, has been used to define some paths through some bushland.
