Section along curve

You can use the new Section Along Curve tool to create a section along any 2D element. This section does not have a depth.

Start by defining the parameters for the Scale, Clipping path and Section in the Section Along Curve palette. Then click the 2D element for the clipping path in plan and select the viewing direction by clicking in the workspace.

A preview of the section is attached to the crosshairs. Before placing the section, you can change its parameters, use to use a new element for the clipping path or modify the Start and End of the clipping path. Click if you want to switch the viewing direction.

The section will not update automatically to reflect any changes you make to the 3D model. As soon as you modify the section, the program will update the section. In order to modify an existing section, select the Modify Section Along Curve tool and click the view border of the section.
You can also open the Section Along Curve palette by double-clicking the view border with the left mouse button or selecting Properties on the shortcut menu of the view border.

Points for calculating the clipping path

You can define the points of the clipping path the program is to use to calculate the heights of the elements. To do this, open the Representation palette by clicking the Representation button in the Section area. This is particularly helpful if the edges are not linear, producing as accurate a section as possible.

The individual settings mean the following:

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.
