This command creates a sewer profile (.PRO) file with manholes,
or will create a pipe profile (no manholes, no manhole width), and
draws it on the screen. It requires that a grid is already drawn.
It begins with the Design Sewer Settings dialog box.
Bottom Manhole Width: Specify the size for the bottom of
manholes. Not available when Profile Type is set to pipe.
Max Pipe Length: Specify the maximum limit for the distance
between manholes.
Min Percent Slope: Specify the minimum slope (absolute
value) between manholes.
Layer name for text: Specify the layer name for annotation.
If you enter a layer that does not exist, it will be created.
Profile Layer: Specify the layer name for pipes and
manholes. If you enter a layer that does not exist, it will be
created.
Drop Across Manhole: Specify the amount the elevation drop
across the manhole in the direction of the profile. Will accept a
negative a value. Not available when Profile Type is set to
pipe.
Snap Prompt: Activates the PVI Snap dialog box. See below
for description.
Pick Plan View Polyline: Allows you to select a polyline
from plan view that represents the sewer centerline. This leads to
the plotting of manhole symbols on the plan view and also creates
default manhole-to-manhole stations.
Manhole Bottom At Pipe Slopes: When checked, the manhole
bottom will be drawn level with the pipe slope.
Profile Type: Choose between Sewer profile or Pipe profile.
Pipe profile do not include manholes.
Grid Dimensions: Specify the grid dimensions on which the
sewer will be designed.
Design Method: Choose whether distances specified are center
or manhole to center of manhole or actual pipe length. Not
available when Profile Type is set to pipe.
New/Append: Choose between creating a new profile (.PRO)
file or appending an existing file.
Depth to Use: Choose between specifying pipe top or pipe
bottom elevations. Not available when Profile Type is set to
sewer.
File Selection dialog
Choose a new profile file name to
create.
Pick Lower Left Grid Corner <5000.0,5000.0>[endp on]:
pick the corner
Select existing ground polyline or ENTER for none: You may
optionally pick a polyline to use for calculating the depth from
the surface as the sewer stations are entered.
Enter station or pick a point (Enter to End): 0
Depth from Surface/<Elevation of manhole>:
935.7
Enter the step up/down in feet <0.00>: press
Enter
Station of second MH or pick point (U,E,D,Help): pick a
point
If the Pick Plan View Polyline option has been chosen, the program will default to the station of the next vertex in the selected polyline. If the Prompt for Snap option was selected in the main dialog, then the Snap Profile Point dialog appears here. The station and slope may be changed to the nearest snap value. The elevation is the free variable and it will change to compensate for any snap. To change the elevation, select the elevation edit box and enter the new value.
Enter the step up/down in feet <0.00>: press
Enter Enter 0.1 if
pipe drops one tenth into manhole and you are designing in upstream
direction.
If you enter a station for the next manhole rather than picking a
point on the screen, then you will be prompted as follows:
Depth/Percent grade/Min grade/<Elevation of manhole>:
939.79
Size of pipe in inches <10.0>: 8.0
Station of next manhole or pick a point (U,E,D,Help):
press Enter
If you picked a plan view polyline, you will be asked:
Draw manholes on centerline [Yes/<No>]? Y Then
you will be prompted for the default manhole symbol to use.
Profile Sewer Settings dialog
Sewer Label Options dialog
Sewer Annotation
Options dialog (Displayed by pressing the Annotation Options
button.)
Select existing ground polyline: pick a polyline or
press Enter to be prompted for each manhole surface elevation
This prompt only appears if no ground polyline was selected
above.
Manhole No. 1 label [MH #1]: press Enter
Manhole No. 2 label [MH #2]: press Enter
