Nonpickable entities

By default, the procedure mode prevents previously selected geometric entities from being selected twice in the same procedure. If you do not want this behavior, you can call the allowRepeatedSelections method.

The following example shows how to allow repeated selections:

step = AFXPickStep(self, self.edgeKw, 'Select a straight edge', 
    AFXPickStep.EDGES)
step.allowRepeatedSelections(True) 
Disallowing repeated picks works only for geometry items such as vertices, edges, and faces; it does not work for nodes and elements.
