You can make multi sheet, it’s ok with dynamo. But when place view on sheet, the standard node of dynamo not good. it’ just add view type : PLAN VIEW, DRAFTING VIEW, LEGEND… EXCEPT STRUCTURAL and SCHEDULE type view.
If you want to continue place view on sheet, i can share u that node.
when i see your node, i feel you don’t understand about input of Views of node Sheet.ByNameNumberTitleBlock, you must give it element’s id from your views, the excel’s input just a string data, so that node can not understand and will say it’s wrong type data.
