Assign Levels Dialog Box

Use this dialog box to assign levels when creating feature lines from objects. You can access this dialog from the Create Feature Lines dialog box.

These options override the levels of the objects that you are converting to feature lines.

Level

Assigns a fixed level to the feature line.

From Gradings

Creates a temporary surface from selected gradings to compute the feature line level. This produces the same result as selecting the grading group surface if you have not created a grading group surface.

From Surface

Assigns levels to the feature line from a surface in the drawing.

Select Intermediate Gradient Break Points

Inserts intermediate gradient breaks when the element crosses surface Triangulation lines, creating level points at these locations.

Note: If no gradings exist in the current site, the From Gradings option is unavailable. If no surfaces exist in the drawing, the From Surface option is unavailable.
