Isolate Washer
 

I am trying to isolate the washers, with this script but it is not working,


def main():

washer_shells = mesh.IsolateWashers(0)

base.Or(washer_shells)
container = base.CreateEntity(deck, "HIGHLIGHT_CONTAINER")
if base.AddToHighlight(container, washer_shells, "RED"):
base.RedrawAll()



and also which function is used for creating RBE2 element

I am trying to isolate washer using this function

washer_shells = mesh.IsolateWashers(0)
print(washer_shells)

it gives me None output.

what could be the problem??
