inquire flat view attributes

[rvn]

Does someone know how to inquire the :base_face, :flat_origin and :flat_direction of a flat view in annotation. I tried to do it with (sd-am-inq-view), but I can't find these things.
We already create one flat view, but we want to have a sheet with a second flat that is completely the same like the first flat. So it would be handy to get these attributes out of the first one.

Can anyone know how to inquire this?
thanks in advance
