Adding Children to a Feature in CAA RADE

To add a child to a feature you need to instantiate the CATIDescendants class. This inherits from your featuer directly. The following code creates a parameter and appends it to the feature in the tree:
CATICkeParm_var Material = spParmFactory->CreateString("Material","Steel");

CATIDescendants_var spDescendants = NULL_var;
spDescendants = myFeature;
