Hi All,
I am trying to create dynamo definition where I want to select element by category, type and level. After selection I want that dynamo enters parameter which I want. Problem is that when dynamo needs to set the parameter error occurs (diferencianing a non-pointer).
What could be the problem?
Hi @brane1012
Currently your connecting string list to filter bool mask node you need to connect elements if your looking to filter elements. Do this changes then you’re good to go.
Hi @Kulkul
Thank you very much for the idea. I will try it immediatelly in the morning on my work and get back to you.
Do you have any idea how would I additionally filter element based on MEP system (so Category + Level + Family Type + System (like Exhaust air, or similar)?
Best regards, Branimir
If you download the MEPover package there is a node Element.System that you could use, with the same structure of filtering you have done with Category, Level and Family Type
from where to get this “Element.System” custom node?
Hi @rafaybukhari,
See the little tag above the node
