You need to define the properties for both Arm1 and Arm2 in a dual-arm system. The Z plate value is initially set to 0.0 and must be evaluated by taking a hit according to the "Fixturing Setup: Volume Definition" topic.
Approach in negative Y
When you edit the properties for Arm2, you must clear or mark the Approach in negative Y check box according to the axes convention for the dual-arm system that you are using. For example, for standard systems such as the Vento, the software selects the check box when you set up the Arm2 parameters.
