Reversing the Direction of the Flow in a Pipe
Use the Reverse Flow command to globally reverse the flow of the current run
by swapping both the invert in with the invert out and the label in and out. Use
this command whenever you define a pipe run with the flow in the wrong
direction.
To reverse the direction of the flow in a pipe
1 From the Pipes menu, choose Conceptual Plan ä Reverse Flow.
2 Do one of the following:
n
Select the run with your pointing device.
n
Press ENTER to open the Defined Runs dialog box and select the run, then
click OK.
After you select a run, the Pipeworks database is automatically searched for a file
with the specified run name and an .mdb extension. The following prompts are
displayed:
Run <{name}> deleted from database.
Conceptual Plan for run <{name}> erased from drawing.
Run <{name.mdb}> file deleted from project.
Run: {name} length: {#} nodes: {#}
Run <{name}> flow direction reversed.
The pipe run is deleted from the Pipes Run database, the conceptual pipe run
plan is erased from the drawing, and the .mdb file is deleted from the project.
The pipe run is then automatically redefined with the reverse flow direction.
Updating the Rim and Invert Elevations of a Pipe
Use the Recalculate Rim command to recalculate the rim, invert, and sump
elevations. Use this command after you define a pipe run and the rim elevations
need to be updated.
The rim elevation can be extracted from a surface. The invert and sump
elevations are specified based on the new or existing rim elevation and the
Invert depth below rim values set in the Pipes Data Settings.
To update the rim and invert elevations of a pipe
1 From the Pipes menu, choose Conceptual Plan ä Recalculate Rim.
2 Do one of the following:
n
Select the pipe run with your pointing device.
n
Press ENTER to open the Defined Runs dialog box and select the run, then
click OK.
All pipe runs are stored in a single Pipeworks database called pipeworks.mdb.
After you select a run, the Pipeworks database is automatically searched for the
run with the specified name.
NOTE
The .mdb file is a Microsoft Access file, so you can view the .mdb file using
Microsoft Access.
