Import Error:No module named Revitservices again

Revit
1

Hi everyone,

I am following ArchSmarters python code to create Placeholder Sheets. I am getting the error as seen in the pic below.

I don’t think it’s the code. I think it has something to do with the RevitServices.dll file and/or its location. If I have made a mistake with the code, please direct me. I followed it from this video. https://www.youtube.com/watch?v=LPk0LMjsyy8

Where should the RevitServices.dll file be located? I am on a work computer and thought it may need to be in the “Users” folder but not sure.

I am in Revit 2023 with Dynamo V2.16.4

Below is my script.

# Load the Python Standard and DesignScript Libraries
import sys
import clr

clr.AddReference('ProtoGeometry')
clr.AddReference('RevitAPI')
clr.AddReference('RevitServices')

from RevitServices.Persistence import DocumentManager
from RevitServices.Transaction import TransactionManager
from Autodesk.Revit.DB import BuiltInCategory, FilteredElementCollector, ViewSheet, Transaction

# The inputs to this node will be stored as a list in the IN variables.
sheetNumbers = IN[0]
sheetNames = IN[1]

# Get the current Revit document
doc = DocumentManager.Instance.CurrentDBDocument

# Start a transaction
t = Transaction(doc, "Create Placeholder Sheets")
t.Start()

# Create the specified number of placeholder sheets
placeholderSheets = []

for i in range(len(sheetNumbers)):
    sheet = ViewSheet.CreatePlaceholder(doc)
    sheet.Name = sheetNames[i]
    sheet.SheetNumber = sheetNumbers[i]
    placeholderSheets.append(sheet)
    
 # Commit transaction
t.Commit()
 
# Assign your output to the OUT variable.
OUT = placeholderSheets

Cheers and thank you!

Try using import RevitServices after you add the reference.

Is this where you would place it? I’m still getting the error.

Check my boilerplate here. I use this in most nodes.

Line 23-26 show how to set up revitservices.

Hi,

add a “s” at RevitServices.Transactions

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

Thank you for your reply Gavin and the boilerplate code! I’m going to stick it in my code to learn from it and mess around with it. I love your vids BTW.

That was it! I was able to take out the “import RevitServices” line as per Nicks post. Thank you all for your help. I looked over the code so many times my eyes were blind to that one mistake. haha. Not even AI could pick up on the mistake.
