I created a Dynamo script to duplicate conduit types in Revit. After running the script, the new conduit types were successfully created. However, when I place the duplicated conduit types in the model, they do not appear in the conduit schedule.
Please suggest
Hi Waseem, welcome 
Please review the following post How to get help on the Dynamo forums
When capturing the workspace please zoom in so the node names are visible, if you use the ‘Export as Image’ menu it will capture the full workspace
The Dynamo graph uses an Excel sheet - what are the details? What are you are trying to duplicate
Are you trying to create new types? Use the native Dynamo ElementType.Duplicate node
What is the schedule of? Is it a ConduitType schedule? Without details it’s impossible to assist
