On Drawboard PDF there are 3 line variations that users can implement to customize their lines:

• Line styles (dashed and dotted line variations)
• Line endings
• Line patterns

Users can implement any combination of line styles, endings and patterns to create endless variations of custom lines. 

To implement line styles, endings and/or patterns to your lines:

2. In the properties navigate to the Line style dropdown
3. Select the style, endings and pattern you want to add to the line
4. Draw the line on the page and it will be drawn with your selected styles

You can also change the style of an already drawn line by:

2. This will launch the context menu
3. From the dropdown select the new line style, patterns and endings you would like to apply to the line
