Design Fill Surface
This command creates fill pile where the sides are a series of
slopes with benches. The side slopes start from a closed polyline.
The perimeter polyline is the toe of the pile, and the slopes will
be up and in from the footprint of the pile. Different slopes can
be used for different sides of the fill. The fill is drawn as 3D
polylines and the fill volumes are reported.
Before starting this command, the perimeter should be
drawn as a closed polyline, 2D at zero elevation, or at 3D
elevations draped onto a surface. You also need a grid file for the
existing ground surface. Design Fill starts with the dialog shown
below where you specify the grid file name.
- Ground Surface: This is
the surface to place the fill pile on. \The Write Output Grid
File allows you to save a grid file at the end of the command
that represents the surface updated with the new pit. Then you can
run Design Bench Pit for the next pit and use the grid file output
from the previous time as the new Ground Surface. The Round
Exterior Corners option holds the slopes around the corners
which makes the benches curve around the corners. Otherwise the
side benches stay straight until they meet benches coming from
other sides at the corners
- Use Elevations From Perimeter
3D Polyline: This will use the elevations on the polyline as
the toe of the fill pile to start the design.
- Write Output Grid File:
This option will create a grid file (GRD) of the fill. It includes
the original ground surface grid file, with the fill pile built
onto it.
- Round Exterior Corners: This option will create rounded corners on
the outside edges of the pile for a more realistic design. When
this is off, the corners are sharp and angular.
- Horizontal & Vertical Interval:
These settings control the
distance to draw the 3D breakline polylines. The horizontal
interval will run down the slope, and across the bench. The
vertical interval will run parallel with the benches. It should be
a factor of the bench height if possible, but not
required.
- Side Layer: This is the layer of the 3D polylines drawn
perpendicular to the benches, and running down
slope.
- Pile Layer: This layer is applied to the 3D
polyline break lines running parallel to the
benches.
- Draw Side Slope Polylines:
This option chooses whether to
draw the 3D polylines running perpendicular to the benches, and
down slope.
- Bench Color: This puts the bench 3D polylines in the Pile
Layer on a different, specified color so they stand out against the
slope breaklines.
- Fill Slope
Format: The slope angle can be defined in percent, ratio or
degrees. This is what is entered in the Fill Slope.
- Slope Group: Four different sets of slope schemes can be
defined. To define the another slope scheme, select other Slope
Group tab. The set of slopes are currently being edited is
indicated by the selected tab. If different sets of slopes are
defined, then the program will prompt to pick which sides to apply
each set of slopes to. All sides are assumed to be slope type one.
it is only necessary to select types two, three and/or four. If
only one slope group is defined, then it will not prompt to select
any additional sides.
- Fill Slope: The slope angle can be defined in percent,
ratio or degrees. This is what is entered in the Fill
Slope.
- Fill Target: The target to fill to for each bench can be
a flat elevation, a depth above the previous surface or bench, or
up to a grid file surface.
- Depth: The Depth must be filled in when the target
is set to depth.
- Elevation: The Elevation must be filled in when the
target is set to elevation.
- Select File: The file must be selected when the target is
set to file.
- Bench Slope %: This setting will slope the benches down for
drainage if desired. Normal setting for flat bench is
0.
- Bench Width: This is the horizontal width for the bench
in feet or meters.
- Bench Name: This is
used for pit design to name the benches for volumes. It does not
have much application in the Fill version of this command.
- Delete: This deletes one line of
data.
- Insert: This inserts a blank row to be filled
in.
- Clear: This clears the entire slope group page,
only the current group.
- Load: This loads a previously saved PIT file with
the template saved.
- Save: This saves the template as shown in the
window.
- Preview: This displays a preview of the current group
to show how the cross section of the fill will
look.
Shown here is a sample fill design in both plan
view and 3D.
The report window appears at the end of the command to display the
volume of the fill in CY or CM.
