Displaying the section

Tool(s): Section Along Curve + Modify Section Along Curve

Using this palette, you can define at which points of the clipping path the program is to calculate the heights of the elements. This is particularly helpful if the edges are not linear, producing as accurate a section as possible.

Label

Element edges

These are the points of intersection between the clipping path and the 3D elements as well as the endpoints of the clipping path. The program always calculates the height at these points.

Station points

If the clipping path is a composite element, these are the points you defined with Station Element.
The program does not take into account points created with Divide Element or station points on elements that are not part of the composite element.

Horizontal points

These are the points where the 2D elements of the clipping path meet, such as the point where a line touches a clothoid.

0-km axis

This is the reference point of stationing, which is only available for a composite element. It is indicated by a cross in construction line format.
You can move the reference point using Ref Pnt in the Modify Element Parameters tool. The value of the reference point is irrelevant.
