I am writing a litle scription on dynamic blocks but i can't find out the use of the lookup action.
When you add a lookup parameter it already has a lookup table attached.
And when you select this parameter when you want to insert a lookup action you get the message:
Lookup parameter already associated with a lookup table.
Is there something i am missing?
Or is this action completely useless?
Since a lookup action needs no association with objects and a lookup parameter can only be used with a lookup action I think autodesk made it so that when you add a lookup parameter it also automatically adds a lookup action, just for time-saving sake. They probably left the option of manually adding the action just to be safe or maybe cause they didn't want to restrict the users.
Note that this is a guess =P
