Hello guys.

I’m trying to delete some duplicates.

 ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/6/a6a163cf6fdde0fbe2efd8e996f6c6f583a88705.png)

It works for fittings, devices and acessories. But does not work for pipes, ducts and conduits.  
What should I change?

What does the error say? If there’s an issue finding duplicates or with the points themselves then that error is going to be passed on to the filtered list.

The points are empty for this kind of elements

So then it’s not going to find any duplicates.

You’re better off getting the elements from Revit’s internal warnings (duplicate instances). I believe there are a few threads already that cover this process. Try looking into those topics for some ideas and give those a try. Then we can help you if you get stuck.

Let’s try use get location center of boundingbox to compare and purge duplicate, it not a best way but can resolve for any type of object elements.
