Flow Arrows

When you add a Thermal Flow Line (with the Add Thermal Flow Line or Add Multiple Thermal Flow Lines options), the direction of thermal flow along a line is indicated by an arrow. By default no arrow is displayed when the Thermal Flow Line is created. By default, only one arrow is initially displayed on each Thermal Flow Line when the Thermal Flow Line is created.
