TraceBoundary is not work with an ellipse or a spline.

[integtech]

Hi, Dears.

I was using a TraceBoundary method well.

However, I found a problem when using it with ellipses or splines.

The return value.Count is 0.

Do I need to do any additional settings to get it to work?
Or is there a method that is used for ellipses ?

It is searched that the same result occurred ten years ago.
I hope it will be improved now.

Thank you very much.

It works well.

I got first method, lockdocument.

The second method , it seems difficult to get the ObjectId of the created region.
