How to create empty sheets

hello I am trying to create empty sheets but this node doesnt seem to be working. I am putting in 2 lists of 30 elements long but only getting out one list of 26 elements long…? Does anyone know what is going on? Thanks

never mind I found out what the problem was, I had duplicate sheet numbers and it omitted them without telling me. Seems like a bug to me, no?

Its not a bug; the Python script within that custom node has a try/except clause that will pass over inputs that fail, i.e. a duplicate sheet number

Ok thanks, any idea why I have 6 duplicate items but the duplicate items node is only finding 5?

Indices 4-8 are duplicates of index 3, so index 3 would be in the “unique” output list for Lists.DuplicateItemIndices

Does any one have an idea why the Tool.CreateEmptySheet stopped working for me?

You maybe? @awilliams

CreateEmptySheets.dyn (27.4 KB)

Seems to work for Revit 2019.2 again, but not for Revit 2020.2.
Any idea how to get it to work for Revit 2020.2?

This is what i get in Revit 2020.2.

[0] [0] Traceback (most recent call last):

  • File “”, line 56, in *
    AttributeError: ‘ViewSheet’ object has no attribute ‘ViewName’

[0] [1] Empty List

Had to change the inputs to not get warnings.

Hi @bvs1982
I’ve got the same problem!
Try to replace a.ViewName=n to a.Name=n so it looks like this:
Now it works for me in 2020.2, but don’t know about 2019.

Found it here: SteamNodes Tool.CreateEmptySheet node ViewName Attribute Depricated
