I have tested this across machines. This is the single slowest operation in any script I have made. In some cases it can take up to 5 minutes for single execution of graph on 9th gen i7, RTX Quadro 4000, 32GB RAM. Is there an alternative way to duplicate sheets that anyone knows of?

Revit 2022 has a built-in Revit node for duplicating sheets, but not sure if it’s going to solve your issue. We use Dynamo to create sheets and place views and a lot of the lag time is based on the complexity and amount of elements in the views being placed. We deal with architectural panels and if there are a lot of elements on the panel (i.e. bricks), the creation takes longer. I may be mistaken, but I think most of the lag is caused by Revit having to regen the views.

It is understandable that this operation would take a long time, just asking around if anyone knows a better optimized and faster duplicate nodes if they exist. But thanks for explaining that this is not abnormal.

You may be as fast as you can get with Dynamo and Python. However, you may gain in speed if you know how to code in C#.

Could you please link any useful resources on this? I am right now duplicating 6 sheets with settings blank, no views, no dependency and it’s taking more than 2 minutes. If I do this manually it creates them instantly.

Can you share your file so I can take a look? Only share a minimal reproducible case - don’t share a graph or file with lots of information/packages etc, otherwise I wont look at it.

Here’s the reproducible minimum. Took over 3 minutes to execute (with any sheet in any project). Yet duplicating manually was instant.

@1bitBoolean Try BimorphNodes v5.1.0. The node is much faster with a few sheets, but I recommend not exceeding 15 otherwise it takes forever. There’s little that can be done about it since its a problem with the way Revit regenerates the document after view & viewport creation.
