Draw Surface Boundary

This command draws the exterior perimeter of a triangulation or grid surface as a polyline. This is a simple way to show the size, shape and location of a surface without adding a lot of drawing entities and file size to the drawing.

The program prompts for the layer of the polyline to create and the type of polyline. A 2D polyline is drawn at zero elevation. A 3D polyline uses the surface elevations. There is an option for Label Polyline which adds text labels along the polyline with the specified name, size and interval. This label can be helpful to identify different surface boundaries.
