Hi @Marcel_Rijsmus, thank you very much for your reply.
When I use the Sheet.ByNameNumberTitleBlockAndView, the sheets were still not created as follow:
Then I rename the excel file name to suit the content, reload the dyn file that from my previous post and hit Run. and miraculously the sheets were created:
I don’t know why the first time it didn’t worked, but after I rename the excel filename and reload the dyn file, it worked.
I create a new project in Revit, run dynamo, load the dyn file, and it worked again… so… maybe I’m in the very basic right track even though I don’t know why it doesn’t work the first time.
I’ll read some more from other posts…
