Civil sections

This interface is used to generate cross-sections along an alignment.

The sections depicted will be as wide as the offset requested on each side of the alignment, and will be repeated at each given interval. The original surface may also be compared with another surface in order to view the differences on either side of the alignment alongside it. In the example below, the surface is compared with one possible road surface. The profiles are read by column, from bottom to top and left to right.

Section	Option	Description
	Section name	The name given to this section configuration, which will appear in the tree at left.
	Surface	The surface used to generate the sections. This is the basic surface that determines which layers can be used as the first layer.
Scales	Hor. Scale	Horizontal scale
	Vert. Scale	Vertical scale
	Offset	Lateral distance required on each side of the centerline of a road or alignment.
	Interval	Difference in chaining required between two sections.
	Reference line	List of alignments available
	Start	Start chaining.
	End	End chaining.
	Reference surface	List of surfaces available as references.
Sections	Preferences	Used to choose the style of section to use. Defined in preferences.
	Draw	Draw the sections in the main window.
	Erase	Erase the sections from the main window.
	View	Call the section viewer.
	Report	Generates a section volume report. Each volume calculation will have its own table.
Drawing Origin	Pop-up menu	Used to specify the first section's origin in the drawing. Right-clicking this field makes it possible to specify a point number or coordinate by picking it in the main window. The pop-up menu can also be used to show or hide the coordinates and PCode. The text boxes give the coordinates of the profile's point of intersection in the drawing (lower left corner).
Volume between 2 layers	Add	Adds a volume calculation between two layers.
	Update cross-sections	Used to add sections to the alignment in order to export them as LandXML.
	Name	Name of the volume calculation. It will be indicated in the report.
	Origin	Original layer for calculating volume. It must be a surface layer indicated in the "Surface" field.
	Reference	Reference layer for calculating volume. It may be part of the surface in the "Surface" field, or the surface in the "Reference surface" field.
