I designed a plaque/sign, which is mostly vector carving, for an 11"x11" work piece. The sign itself is 10"x10", and I had planned to have a board which is 18"x11.25" when I carved it, to allow it to stay under the rollers, etc.

I have since decided I would like to roughly double its size. Of course, there's no way to carve a 20"x20" sign in one board.

So; would I need to redesign it from scratch?

Or is there a fairly easy way to scale all vectors up, let them hang halfway off the board so only half is carved, and then copy/paste that and do the same for the other half?

Some more info; it is a circular sign
