The Flow Direction symbol can be used for a graphical indication of the flow of a branch on a drawing. When dropped on top of a tube or duct shape, the flow direction symbol automatically aligns with the current flow and it reacts on the connectors’ moving or re-sizing. It is also automatically adjusted on the reversing of the flow direction. The flow direction symbol can be created using Import Shape Wizard and then dropped from the stencil as any other shape. To achieve proper behaviour it is important that before the symbol is imported its orientation corresponds with default flow direction going horizontally form left to right. The shape should also have one outwards connection point which will be used to attach to the connector.
