Assign Elevations Dialog Box

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

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

Elevation

Assigns a fixed elevation to the feature line.

From Gradings

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

From Surface

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

Select Intermediate Grade Break Points

Inserts intermediate grade breaks when the entity crosses surface TIN lines, creating elevation 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.
