Learn how to force surface triangles to align along a line.
This video demonstrates:
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 optimisation, all surface triangles will align an edge with the line for a smooth and consistent gradient.
In the Optimisation 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 optimisation 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 optimisation.
Use Aligned Edges in Grading Optimization to create linear elevations with a consistent slope, which is necessary for wall locations and car park ridge lines.
