Each Profile Window is based on a feature called the Fence Section Feature. It is possible to display additional projected or intersected features in a Profile Window.
Intersected features penetrate the vertical plane of the profile. These intersection points can be displayed with a symbol of your choice.

Projected features are displayed on the profile by projecting perpendicularly onto the fence section.

Projected features are often on (or near) the fence section. If you draw features (other than the fence section) in a Profile Window they are automatically added to that windows list of Projected features.
A user configurable list of intersected and projected features is stored with each profile. This list can be accessed from the Active Window (Profile) Options dialogue box.
To display intersection of ROADCL on the creek section (SECTION-0):
Select Profile Window SECTION-0. With the cursor positioned in the Profile window, right-click and select Active Window (Profile) Options.
Click on the Projected/ Intersected button.
In the Intersected Features group box, press the Select button. Find and Select ROADCL-0. (figure below) Press OK until you have returned to the main screen.

Home | Select | By Name from dropdown list. Press the Un-select All button and select the ROADCL-0 from the list with a double-click. Press OK to return to the main screen.
Right-click in the Profile Window, and select Modify Selected Feature(s) | Line-types, Symbols. Select symbol Triangle (Large). Press OK. A large triangle is now in the center of the creek profile indicating the position of the road centerline feature. Use Zoom extents or Pan the view if the road centerline is not visible.
Note the elevation of the road centerline lies on the streambed. This is because the road centerline feature has been 'draped' over the TIN model.
