Use the line render options to control the appearance of lines in Hidden Line, Dashed Hidden Line, and Final Shaded Polygon modes. These settings apply only to the current drawing; they remain in effect in the current drawing until the settings are changed. The current line render settings are saved when you create a template (see Creating Templates).
To set line rendering options:
Select View > Rendering > Line Render Options.
The Line Render Options dialog box opens.
Click to show/hide the parameters.
Select the line render options, and click OK to change the settings for the file.
