Duplicate View With Detailing Simply Duplicates View - Detailing Not Included

[stewartcartmell]

Following along with this great sample found at revitapidocs (pasted below), I've changed out the "AsDependent" bits to "WithDetailing", the view Duplicates but does so without detailing. Strangely, line 7 in the code below returns -1 even though a new view is created and appears in the Revit UI. This leaves dependentView = null, so line 9 fails the check.

I also noticed the same behavior in pyRevit's Duplicate Selected Views tool and reported the bug on their github page.

I've checked this in Revit 2022 & 2023.

Here is the sample code. Again, I have changed "AsDependent" to "WithDetailing", otherwise my code is the same as below. The calling function sets up a Transaction. The Transaction succeeds and appears in the UI undo history:

public View CreateDependentCopy(View view)
{
    View dependentView = null;
    ElementId newViewId = ElementId.InvalidElementId;
    if (view.CanViewBeDuplicated(ViewDuplicateOption.AsDependent))
    {
        newViewId = view.Duplicate(ViewDuplicateOption.AsDependent);
        dependentView = view.Document.GetElement(newViewId) as View;
        if (null != dependentView)
        {
            if (dependentView.GetPrimaryViewId() == view.Id)
            {
                TaskDialog.Show("Dependent View", "Dependent view created successfully!");
            }
        }
    }

    return dependentView;
}

Hi @stewartcartmell ,

I tested the sample code at my end and everything is working fine on my end.

Could you please provide me the below details to reproduce the issue?

1)A simple non-confidential Revit file to reproduce the issue
2)Screenshots of expected result and observed result
3)A simple non-confidential sample code
4)Revit version details.

Hi Naveen,

So sorry, the strangest thing happened. When I started my PC this morning the duplication script worked without issue. I had restarted Revit, and then later the PC yesterday to see if that would help, and when it didn't I wrote the post. I must have been mistaken. Thanks for taking the time to check this for me, I did not mean to waste your time. In the future I'll give the PC an overnight rest to see if that helps again 😉
