Type -linetype↵ and use the Create option. If you feel quite confident, you can even create linetypes on the fly, using the command-lineįorm of the LINETYPE command. The linetype would be displayed as shown below. This pattern continues for the length of the line, ending with a dash 0.5 drawing units long. This indicates a repeating pattern starting with a dash 0.5 drawing units long, a space 0.25 drawing units long, a dot, and another space 0.25 drawing units long. The following definition creates a line with two dashes of 0.25 units, followed by two dots, all separated by spaces of 0.5 units. ✦Each item is separated by a comma, there are no spaces, and the maximum line length is 80 characters. ✦A space is indicated by a negative number. ✦ A dash is indicated by a positive number.
With simple linetypes, you’re limited to dashes, dots, and spaces, which are measured in units and specified as follows: The second line of the linetype syntax is its definition. ✦If you include a description, precede it with a comma. ✦The description is limited to 47 characters. ✦ Always start the definition with an asterisk. The first line contains the linetype name and an optional description, formatted as follows: In the syntax for creating simple linetypes, each linetype is defined using two lines of text. You commonly use Notepad to edit a linetype file. Of course, be sure to make a backup copy of acad.lin or acadlt.lin before you edit it. Linetype files are text files and must have a. You can add your own linetype definitions to this file or create your own linetype files. The default linetype file is acad.lin for AutoCAD and acadlt.lin for AutoCAD LT. Complex linetypes usually have dashes and/or dots, but also contain text and/or shapes. Simple linetypes consist of only dashes and dots. There are two types of linetypes: simple and complex. Hatch patterns often represent textures or materials. You use hatch patterns to fill in closed (or almost closed) areas. They apply not only to lines, but also to polylines, arcs, ellipses, wireframes, and solids-in fact, to most objects. Linetypes are useful whenever you don’t want a continuous linetype. You can then use them in your drawings in the same way that you use the linetypes and hatch patterns that come with the software. However, when these do not serve your particular needs, you can create your own linetypes and hatch patterns. Creating Your Own Linetypes AutoCAD and AutoCAD LT come with a large number of linetypes and hatch patterns.
