Specifies the symbol that the system places when the pipe permits flow to travel in only one direction through the pipe.The following image shows the Unidirectional Symbol placed on two pipes that each allow flow to travel in only one direction.
1 - Pipe |
The content module Flow Direction (DrawingFlowDirectionContent) checks the pipe to determine in which direction or directions the flow travels. The module then selects the corresponding flow direction symbol to be placed on the pipe. In this case, because flow travels in only one direction through the pipe, the software places the Unidirectional Symbol on the pipe.
