Hi all,
I’ll try explain what I want.
In a schedule I have a number of items (in this case “Pipe Accessories“).
Is want to check if an item is numbered (instance parameter). If so then other items that are the same (same Family and Type) also needs to get that same number.
The problem lies within the Type-parameters vs Instance-parameters I think.
My code sorts the same items together (the List.GroupByFunction node).
I can’t get it accomplished to get the “LOM_C_prefab_positienummer“ parameter from these types.
If I get those values from the instances it goes well of course, but then I can’t get them sorted on Family and Type (or Element.Id what I was trying now).
Hope I make myself clear a bit
