#The inputs to this node will be stored as a list in the IN variables.
sheetnames= IN[0]
sheetnumbers = IN[1]
titleblocks = IN[2]
viewtypes = IN[3]

sheetlist=[]

for na,nu,t,v in zip(sheetnames,sheetnumbers,titleblocks,viewtypes):
	sheetlist.append(Sheet.ByNumberTitleBlockAndViews(na,nu,t,v))

OUT = sheetlist

How i use this node right?

I don’t understand the purpose of this exercise, but let’s say that you have a good reason to do that instead of just using the ACTUAL node.

Here’s how I would do it:

# Copyright(c) 2017, Konrad K Sobon

import clr
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)

import sys
pyt_path = r'C:\Program Files (x86)\IronPython 2.7\Lib'
sys.path.append(pyt_path)

sheet_names= IN[0]
sheet_numbers = IN[1]
titleblocks = IN[2]
views = IN[3]

sheet_list=[]

try:
    errorReport = None
    
    for na,nu,t,v in zip(sheet_names,sheet_numbers,titleblocks,views):
    	sheet_list.append(Revit.Elements.Views.Sheet.ByNameNumberTitleBlockAndView(na,nu,t,v))

except:
    # if error occurs anywhere in the process catch it
    import traceback
    errorReport = traceback.format_exc()

# Assign your output to the OUT variable
if None == errorReport:
    OUT = 0
else:
    OUT = errorReport

So first and foremost, the actual API call here is Sheet.ByNameNumberTitleBlockAndView() This particular call would match your input types. The reason you were getting the error that Sheet is not defined is because you imported the Revit namespace and then called a method that was at Revit.Elements.Views. So you either import that namespace directly or call it with the long form like I did.

Anyways, like I said, this works, but there are so many things wrong with this approach that I don’t even want to start listing them all off.

Cheers!
