Pipes
If you will be using the same type of pipe throughout your system, you can define the default pipe type and values that are used when drawing pipes, using the Pipe Data tab in the Configuration Options dialog. When the default pipe values are set, each time you add a pipe to the system, the pipe type and values are automatically defined for the pipe. You can customize the values for an individual pipe in the system, by editing its values in the Pipe pane or in the Pipe diameter data dialog. The Pipe diameter data dialog contains a list of the pipe materials and sizes available in the pipe database and additional properties specific to a pipe in the system.
For more information about using default pipe values, see: Setting up the System Options
NOTE: Be sure to enter the values for the pipe’s properties in the units displayed next to the field. For example, if you are using metric units, and m for meter is displayed next to the Length field, enter the pipe length value in meters.
