About the Feature Lines Collection (Prospector Tab)

Use the Feature Lines collection in the Prospector tree to manage feature line styles and layers. You can also view feature line information, such as length, elevation, and grade.

Feature lines can exist outside of a site or within a site.

Tip: You can grade from a feature line only if it is in a site. If a feature line site is set to <none>, it cannot be used for a grading baseline.

Feature lines outside of a site are shown in a top-level Feature Lines collection in Prospector. Feature lines inside a site are shown within the Site collection in Prospector.

A black dot glyph indicates a feature line in the collection.
