Draw Section View

Draw Section View tool creates a 3D section view that can be used for design purposes. A section view is a rotated view along a section line.

A section view is not meant to be plotted on paper. As its name implies, it is a rotated cross section view drawn at the true 3D position of the section line. This makes it ideal for design purposes. If you use a section view to place elements, they are drawn to a true 3D position.

The tool draws a line for each surface at the section’s location if the surface type is selected to be drawn in profiles. The symbology of the line is related to the surface type and determined by settings in Surface types category in TerraModeler Settings. Optionally, the elevation range can be drawn including grid lines and labels.

6. If Z range is set to Prompt for, the Section view range dialog opens:

Define a Start elevation, End elevation, and vertical Step size and click OK.

The view is rotated to show the section with the section line start point on the left and the section line end point on the right. The depth of the view corresponds to the given depth value of the section.
