Defining Ponds

You can use the Define Pond commands on the Grading menu to define your

pond perimeter from an existing polyline, or to define the 3D pond information

from existing contours.

The Define Pond ä By Polyline command names a pond that you can then

select when you are using the Pond Slopes command to define the pond slope

information. Use this command in place of the Pond Perimeter commands if

you have an existing polyline in your drawing that you want to use as the pond

perimeter.

You can also use the By Polyline command to rename an existing pond or

define a new pond from an existing pond.

The Define Pond ä By Contours command defines existing contours as a pond.

The contours you select provide all the data required for creating a pond

perimeter, pond slope, and a pond bottom. This command is especially useful if

you have an area of depression contours that you want to use as a natural basin

structure.

Defining a Pond Perimeter from a Polyline

Use the By Polyline command to create a pond definition from an existing

polyline in your drawing. You can use this command in place of using the Pond

Perimeter commands. This command names the pond and creates a <pond

name>.pnd file in the c:\Land Projects R2\<project name>\hd folder.

To define a pond perimeter from an existing polyline

1 From the Grading menu, choose Define Pond ä By Polyline.

The following prompt is displayed:

Select polyline:
