Launch the program from ribbon/Add-In tab or using command TLMarker

Select a Civil 3D Alignment, ProfileView, SectionView or SampleLine object. Follow the prompts and pick points along the selected object to visualize markers on the corresponding entity.

The elevation at which point objects are drawn can be set to actual elevation, default or the elevation variable. If you'd like to draw all points at elevation 10, for example, you can issue the command elev and set the current elev at 10.

This app uses the .NET API function FindXYAtOffsetAndElevation to determine the height of the section view. Due to the way Autodesk has implemented its functionality, if the elevation range of the section view is set to Automatic, the lines drawn may appear too short as the function returns the height of the section itself and not the height of the grid.
