I am trying to sort and group all my pipe hangers into groups of the same Hanger Type, Size and Rod length and apply a sequential number to each “group”. FIltering and sorting seem to be working but the renumbering part is failing, the Element.SetParameterByName is giving me a error of "Dereferencing a nonpointer.
What do i need to do to get this working?
Hi @Peterpiper
You need to connect elements to setparameter input element right now your connecting strings.
Yep try using the sorted list output rather than the sorted keys output
I tried using the List.Count Occurrences node in the post above to bring Elements back in and I still get a non-pointer. If I go back to the beginning to get Elements, I will lose my sorting. Any thoughts?
Try connecting the bool mask from all elements of category
That cleared the non-pointer error, but now it gives me a “parameter not found” error. Do I need to insert another Get Parameter group at the front?
Found another thread and fixed my own problem - Controlling visibility parameters in titleblocks
I was using “Sheets” instead of “Title Blocks” at the front and was not using binary control 0/1 in a code block for ON/OFF at the set Parameter node.
Works now
