Hi everyone,
I want to developp a numerotation tool. I would to select model elements in the order that I choose and then extract a list of these elements in the order that I had click. I’d search a lot of time and I don’t found anything about that. I know it exist the node “Select Model Elements” but, with this node, we can’t select with click but only with a box selection.
May have you a solution ?
Thank you in advance for your responses.

I did this long time ago and I just consider it unorthodox. 
Infinite_Selection.dyn (3.3 KB)
Ok, in order to achieve it:
An infinite loop, or almost infinite in your context.
Calling Selection.PickObject(), not plural.
Collect the element
Wrap step 1 and 2 into a try block. Break the loop in exception.
When u’re done with selection, press ESC to trigger OperationCanceledException then
break the loop.
Output your collection.
A bit easier is this node from the springs package: 
@jshial Thanks for this ! I think it is exactly what I need !
Thank you also @jacob.small for this node. In this case I prefer use a python script to work next on the selected element in the same script.
