Mounting holes in Protel

First, let me thank everyone for their patience. I do not want to be a
bother and try to help myself as much as I can before posting here.

I am at the point now where I need to spec mounting holes for some AMP
circular connectors. I have successfully created the parts in my
Protel library, but I used a circular overlay to depict the mounting
holes.

How should I properly do this in order for it to appear in the drill
drawing?

Thank you one and all. You have always been so tolerant and helpful.

Create pads for the mounting holes, making the hole diameter clearance for
the screws and the pad diameter about the same as the washer you intend to
use. Number these pads zero (0) and they won't pick up any connections.

Just for variation on the answers, I commonly will name my
mounting pads in a footprint, "MTG". Likewise on pass-thru
connectors I name the pass-thru hole pads, "Passthru". It is then
very easy to find them and put them into a pad class for rules.
Or the neater trick is you can write a rule for one pad by it's
pad name and it works for all pads with that same name.

I place individual pads for mounting holes. Such holes can also
be
placed in the footprint - just give them a pin number of 0.

You can define both the pad size and the hole size as required.
I
usually make the pad the same size as the screw head or other
hardware
- that ensures I won't put tracks too close to the hole.

It is possible to define the hole as "unplated", but I expect
that
will require an extra manufacturing step, and I don't see any
problem
leaving plating in a mounting hole.
