Let's look at the orientation of the nozzle around the vessel.
From the example shown above, the 0º position is at the top (North) and the nozzle at position 90º is to the right. Therefore, the angles of the nozzle increase in the clockwise direction. However the zero position can occupy the North, West or East position as you need. The angle can increase in the clockwise or the counter-clockwise direction. The controls are on the Configuration dialog screen. To get the Configuration dialog screen, go to the Tools tab, click Set Configuration Parameters, and then select the Set Default Values tab.
