I feel like an idiot for taking this long to discover this little trick, but better late than never I guess…
You don’t align additions to the existing cut, you align them to the PREVIEW! And they come out perfectly!
I forgot to add the hash scores to a ring that I was cutting out of a scrap in the far reaches of the bed, and I’d already cut out the blinking ring before I realized it.
I just created another quick file that included both the ring and the correctly placed hash marks to be scored, and dragged that onto the still open file…
Placed the new ring so that it covered the old Preview ring precisely, (even though it appeared to be offset from the actual cut underneath), then Ignored the rings and ran the Score. It laid the hash marks exactly where they were supposed to be on the cut.
Somebody whack me upside the head for taking this long to figure this out!
