Design Tab

The tab Design is only available if the marking field design was activated under General.

  • Pipe selection –The option menu specifies how the pipe selection for the design calculation takes place. The following options are available:
    • Entire network – The list is ignored. All pipes of the network are dimensioned.
    • By zone – All pipes which belong to one of the zones in the list are dimensioned.
    • By pipe classes – All pipes whose pipe class is specified in the list are dimensioned. Note that the pipe classes must be activated explicitly for the design calculation so that they are considered! See Pipe Classes.
    • Selected pipes – Only the pipes which are specified in the list are dimensioned.
      • Select by graphic – Starts a command to select a pipe from the drawing. The selected pipe is examined and the adjusted selection criterion (zone, pipe class, pipe) is added to the selection list.
      • Deselect by graphic – Starts a command to select a pipe from the drawing. The selected pipe is examined and the adjusted selection criterion (zone, pipe class, pipe) is removed from the selection list.
      • Delete selection list – Removes all entries from the selection list.
        • The list must be rewritten, otherwise the information for design calculation is incomplete.
      • Edit selection list – Edits the list of objects that are in the scope of the design calculation.
        • By clicking on a row and/or a focused list by hitting the space bar, the marking of the selected row is switched on/off. A marked row is in the selection.
        • By pressing the input button or the "OK" button, the selection is applied and the dialog mask is closed. By pressing the ESC key or the "cancel" button, the dialog is closed and the changes not applied.
  • Limit values – Using the marker fields, either the max. pressure loss and/or the max. flow rate of a pipe is considered as design criterion.
  • In the input fields the maximally permissible limit values are set.
