Well, thanks. From your message I went back and tried push/pull, and oh, so easy.
I am somewhat confused by the terminology of the spaces between the tails -- it can't be the pin because the pin is in the other board.......?
Anyway, draw the shape of the first pin in the tail piece and copy it down the board, then push to eliminate. Transfer key points from the female space with guidelines to the other board, draw the space between the pins, copy down the board, then Push into the board the required depth. It looks like the ends (the last pin) has to be manually adjusted (drawn) unless the board width has an even number of pins, properly spaced. Still, not a big deal.
Couldn't be more simple, once I was "pushed" in the right direction. Thanks.
