Determines contours up to spill point and creates a polycontour group ready for volume table or graphs.

Keyboard Command: SurPndSpl

Procedure:

1. Open the drawing containing the surface to evaluate.
2. Initiate this tool from the menu, ribbon or command above.
3. Change any default parameter shown in command area.
4. Pick two points to define a rectangle that should contain the depression low point.
5. Pick a desired depression center or press enter to accept the found point.

Settings:

• Project: The distance to use for spillway projections.
• Densify: The distance to densify the brim contour for inspecting projection vectors.
• Report: Determines whether a report is displayed after processing.

• The highest elevation obtained before contours open up is displayed at the command area.
• This tool evaluates the outer direction at each vertex and draws pointers on those that slope down.
