Displaying Setups, Associated Operations, and GCDs
You can understand which setups are active and which operations are performed from that setup to machine specific GCDs, by using the Manufacturing Process Pane, shown below.
Each process will have one or more part Setup operations underneath it, with the name of the specific setup or turning axis GCD following in parentheses. You can perform the following actions to better understand what machining is performed from each setup:
• If you click on a Setup node, the aPriori Viewer window will display the associated axis in yellow, so you can understand the direction of the axis and therefore the orientation of the part in that setup.
• If you right-click on a Setup node and select Highlight Associated GCDs, the aPriori Viewer window will display all GCDs that are machined from that setup, in yellow, as well as the setup axis itself .
• If you expand the Setup node, you will see nodes under it representing different types of machining operations (e.g., Finishing, which in turn has nodes representing different types of surface finishing operations such as facing , side-milling, or contouring). Under those specific operation nodes will appear the specific GCDs machined by each operation. In the example above, PlanarFace:2 is Faced, on the second part setup which is in the direction of SetupAxis:2.
To see both active and inactive setup axes, click on the Setup Axis tool 
in the Viewer tool bar, then select Display Setup and Turning Axes… The resulting window allows you to independently display both active and inactive (candidate) setup axes.
