Hello,

I have a problem in my revit model that I don't know how to solve. I made a toposurface in the "existing" phase, then I made several building pads in a new phase called "desmonte", after that I used the tool Graded Region using the toposurface of the "existing phase. This tool gave me two options: Copy the same as existing or Copy using just boundaries.

In this stage, when I click any of the two options, is when the error is produced. A warning is showed: "Se ha producido un error inesperado en Revit. La operación se ha cancelado para evitar que se dañe el proyecto.", referring to the element "(Elemento suprimido ) : ID = 240260"

Actually I modified the phases mechanism. I moved everything, the toposurface and the building pads, to the "new construction" phase, but Revit still returning the same error.

The error export is:

The Revit file which I gave me this error is attached.

Thanks in advance.
