Isometric drawings commonly have annotations to denote the direction of fluid flow through pipe as well as through pipe components. To specify flow direction in the model, use Isogen Configuration to define when and where flow arrows are placed on isometric drawings.
The options for flow arrow placement are in Drawing Area.Content.Flow Arrows. The Show on Pipe property toggles all flow arrows on and off. If Show Flow Arrows is set to True, you can also specify component arrow placement. You can set Show on Components so that component flow arrows appear beside components such as valves. When you configure your isometric styles, you can set Show on Components to match your company specifications. Thereafter, you can control all flow arrows on the isometric drawing by toggling Show on Pipe on or off.
