)
 
 
-- Create All Custom attributes
for obj in $ do ( 
 
xxx = attributes Custom_Attributes
(
parameters main rollout:params
(
FSpread type:#float ui:FSpread default:0.0
FBendUp type:#float ui:FBendUp default:0.0

)

( 
spinner FSpread "Spread" type:#float
spinner FBendUp "Bend Up" type:#float
spinner FBendLow "Bend Low" type:#float
)
)
