A Pipe Flow Expert system can be displayed in Isometric mode or Standard mode. The system information such as pipe sizes, pipe lengths, node elevations etc. do not change when the view of the system is changed.


When an Isometric view is transposed (flattened) to a standard view, any vertical lines from the isometric view will be drawn at 45 degrees. This happens because Pipe Flow Expert does not allow a drawing to contain nodes which sit over other nodes, or nodes which sit over pipes. 

This restriction has been applied to avoid confusion.


With the ‘Isometric to Standard’ type of transposition the result can be visualized as an offset view from a high overhead position, where the vertical lines can still be seen, i.e. the result  looks similar to a plan view but it is not an exact plan view (where some of the lines which were vertical in the isometric view  would not be seen in an exact plan view). 


When a Standard view is transposed to an Isometric view the result will be a flat view of the current drawing in the isometric plane. The user may then adjust/move node positions as required to make the drawing appear 3D on the isometric grid.


To change the system view:

  1. Click the ISO Mode On / Off Toggle button, ToolButtonToggleIsoViewOnOff02.dib, on the toolbar.


  1. A new view of the system will be displayed.


  1. Select the ‘Drag and Move’ mode and adjust the node positions as required.


  1. Use the drawing menu to select ‘Isometric tank View from Right’ or ’Isometric Tank View from Left’.



The default drawing grid can for new systems can be set in the Editor Tab of the Configuration Options dialog.
