Draw Center Line Option

The Viewer normally draws the survey line down the center of the passage along with the passage models. Sometimes, this center line is superfluous and makes the plot complex and confusing. For this reason, the Viewer allows you to include or remove the centerline.

Options. To enable or disable this option, check or uncheck the “Show Centerline” option in the Passage Modeling window. You can set the centerline color by selecting the Preferences->Set Colors and Fonts option from the menu bar.
