I am afraid that you have made an incorrect assumption. I do not own
Winline. A friend who does have it, brought his machine over and we tried
to get my plotter going with that. I still would like to buy a version
from someone who no longer needs theirs.

Small cutouts like those in the pads you are describing are usually
restricted to slots or cutouts with a radius at each end or corner. This is
because they are usually created using spinning drill or router bits. There
are many ways to specify slots unfortunately none are as simple and

Dennis,
the main benefit is for SMD designs with components on both sides.
If the panel is laid out correctly (i.e. symmetrically as flipped), the
assembly process can use one set-up and run the boards through the one line
twice. During the first pass board A has it's top side components
Having alternate boards flipped in a symmetrical layout means that
only one solder paste screen is required. Also, the same placement
control files and machine setups may be used, since the assembly panel
looks the same whichever side is up. In really high volume it's not
so much an issue, since

In fact, I have a job at the moment where it would be a really useful
tool. There are two boards that plug together component side to
component side. If such a tool existed, I could place components
on both sides of a single outline so that I could check for
interferences as I go.

Sean,
What is the size of the cutout you need? 1/10 headers typically have square pins.
If the switch and the jack are going to be soldered to the board I would use a round
hole for all of the pins. For a majority of applications I use a finished hole five
over corner to corner, the
