Converting a 3D Pond Perimeter to 2D
You can flatten a 3D polyline by using the Convert 3D to 2D command. This
command changes the elevations of the 3D polyline vertices to zero.
To change a 3D polyline into a 2D polyline
1 From the Grading menu, choose Pond Perimeter ä Convert 3D to 2D.
The following prompt is displayed:
Select by Layer (Selection/Layer):
2 Do one of the following to select a polyline:
n
Type Selection, press ENTER, and then select the polyline(s) that you want
to convert.
n
Type Layer, press ENTER, and then select the polyline on the layer that you
want to select.
3 Press ENTER to convert the 3D pond perimeter to 2D and exit the command.
Saving a Pond Perimeter
To store the geometry of a pond perimeter, you can use the Save Perimeter
command. This is a good practice in case you make a mistake on your current
pond perimeter and have to redraw it. You can use the Import Perimeter
command to import a saved perimeter into the drawing.
This command creates a <pond perimeter name>.psp file in the
c:\Land Projects R2\<project name>\hd folder.
WARNING!
This file stores only the pond perimeter geometry, and does not store the
pond slope data. Pond slope data cannot be re-imported into a drawing;
it must be recreated from the pond perimeter.
To save a pond perimeter
1 From the Grading menu, choose Pond Perimeter ä Save Perimeter.
The following prompt is displayed:
Select polyline:
2 Select the pond perimeter in the drawing.
The Create Pond Shape dialog box is displayed.
3 Type a name for the pond perimeter file.
4 Click OK to save the pond perimeter.
