To Add a Simple Linetype to an LIN File

Open an LIN file in a text editor that saves in ASCII format (for example, Notepad on Windows® or TextEdit on Mac OS®).
Create a header line that includes an asterisk and a linetype pattern name. The name of the linetype pattern is limited to 31 characters.
For example,
```
*BORDER,Border
```
(Optional) Include a description on the header line, follow the linetype pattern name with a comma and description text.
For example,
```
*BORDER,Border __ __ . __ __ . __ __ . __ __ . __ __ .
```
Create a descriptor line that follows these rules:
- All linetypes must begin with a dash.
- Enter zeros for dots.
- Enter negative real numbers for spaces. The value defines the length of the space in drawing units.
- Enter positive real numbers for dashes. The value defines the length of the dash in drawing units.
- Separate each dot, dash, or space value from the next with a comma.
- Use a space between a dot and a dash.
For example,
```
A,.5,-.25,.5,-.25,0,-.25
```
