Redesigning the System
After a pipe system is solved, the pipe system is read-only in the Drawing pane. If you decide that
you want to modify a solved pipe system, you can return to the Drawing pane in design mode by
clicking the Re Design button on the toolbar.
If you want to retain the original solved pipe system and the calculated values for the system before
you redesign the pipe system, be sure to save the pipe system and results before clicking the Re
Design button.
When a pipe system cannot be solved, additional information is displayed in the Results Log and the
message, ‘The network was not solved. See log details above.’, is shown. Clicking OK on the
Results Log automatically returns you to the Drawing pane in design mode.
Amending the System
Making amendments to your system usually involves changing the diameter, length or material of a
pipe or group of pipes. It may also involve changing the node elevations where the pipes are linked.
Amendments can be made in a number of ways:
a. Use the Edit Grid to display, filter and edit the data for Pipes, Nodes, and other items.
b. Click on the pipe or node and update the entries shown on the Pipe Pane or the Node Pane.
c. Set the Default Pipe data, select a group of items to be amended, or select a collection of
individual items and then copy some or all of the Default Pipe attributes to the selected items
These amendment options are described in the ‘System Amendments and Group Updates’ section
of this document.
