Filleting a Pond Perimeter
When you draw a pond perimeter using the Pond Perimeter ä Draw command,
you can only create straight line segments. Use the Pond Perimeter ä Fillet
command to fillet (round) the pond perimeter at vertices that you select.
NOTE
This command removes all extended entity data for an existing pond. This
means that the pond loses its definition and any shaping data applied to it.
You must re-create the pond slope data after using this command.
NOTE
The polyline you fillet must be a 3D polyline. You can use the Convert
2D to 3D command to convert an existing 2D polyline to a 3D
polyline. Ponds that you draw with the Pond Perimeter ä Draw
command are 3D polylines.

Type a fillet radius and press ENTER, or select two points in the drawing to
define the radius distance.
A prompt similar to the following is displayed:
