To Track Stations in Alignments, Profiles, and Sections

The Chainage Tracker provides visual cues to help you locate the chainages that match your cursor position when working with alignments, profiles and sections.

• When the cursor is above a horizontal alignment, and one or more profile views for the same horizontal alignment are in the drawing, a temporary line is drawn in each profile view at the chainage defined by the orthogonal projection of the cursor onto the horizontal alignment. The temporary line is drawn to the full height of the profile view, and moves as the cursor moves.
• When the cursor is within a profile view, a temporary line is drawn orthogonal to the horizontal alignment at the cursor's chainage. The line extends 200 world distance units to the left and right sides of the horizontal alignment. As the cursor's position changes in the profile view, the temporary line's position is redrawn at the new chainage location.
• When the cursor is within a section view, a temporary line is drawn orthogonal to the horizontal alignment at the chainage of the cross-section view. The line extends 200 world distance units to the left and right sides of the horizontal alignment. Additionally, a vertical line is drawn in each associated profile view. The vertical line is drawn at the chainage of the section view.

This setting is controlled per drawing.
