Thank you Tom_Kunsman and Yna_Db. You both pointed me to great resources. Unfortunately after playing around with the examples given in other posts I can not get the results I am after. Please see attached .dyn file for a working example of what I am trying to achieve. The attached graph works perfectly for collecting the elements in the active project, but does not pick up any of the linked elements. I am trying to modify the graph to perfume the same function, but picking up all the elements both within the active model and the linked models. Again any help would be appreciated and I thank you for the help given thus far.
