This node includes required and conditionally required PSOs. A conditionally required PSO is one that is required if you have entered a nonzero value for a particular, related PSO. For example, Average Diameter of Large Round Holes is required if you have entered a nonzero value for Number of Large Round Holes.
If you don’t enter a value for a required PSO, the part fails to cost. If you don’t enter a value for a conditionally required PSO when its associated condition is met, the part fails to cost.
This section lists the PSOs in this node that act as substitutes for the geometry extraction performed for GCD-driven process groups. Other PSOs associated with this node are listed in User Inputs for Sand Casting.
