In Grading Optimization, you use the Aligned Edge grading object to create precise surface geometry along a line. The Aligned Edge is a polyline sketched across a surface. During optimization, all surface triangles will align an edge with the line for a smooth and consistent grade.

In the Optimization Options dialog, set the global Maximum Slope constraint to 15 percent. In this example, all weights are set to zero and the iterations are set to 25,000. This reduces the optimization time with limited results.

Exaggerate the elevations using the slider to enhance the visible depth of the surface.

You can see that a well-defined line was considered with the adjacent triangles during surface optimization.

Use Aligned Edges in Grading Optimization to create linear elevations with a consistent slope which is necessary for wall locations and parking lot ridge lines.
