If you do printouts of the layers in which the via occurs, there *should* be
some copper surrounding the hole. The thickness of this depends upon the
diameter of the via and the diameter of its associated hole (both of which
can be set in the dialog box invoked after double-clicking on the via).

Gerber files should also be similar in nature. But you may want to look at
selecting the option of including unconnected Mid Layer Pads. (There is a
checkbox for this in one of the Tabs of the associated dialog box that can
be invoked from within the CAM Manager Server.)

If you want holes for mounting purposes, it sounds as though you want "just"
holes, with no copper either inside them or surrounding them. Refer to my
other recently despatched posting (Subject: Re: Just a hole) for details of
how to achieve this.
