I keep an svg file of a straight line. Occasionally when I have mis-measured, done calculations wrong, etc - I just need just a cat hair taken off something. Ok ok, sometimes it is a bit more than a cat hair. Anyway, I just load my handy dandy line, resize it, move it to where I want it, and make the quick cut.
I have not seen anyone else mention this - if they have my apologies for re-stating your idea. This simple trick has saved me a bunch of times when I was too lazy to re-do a project but just needed a nudge to get one out of my MewPew.
I thought of doing this but didn’t have any confidence on where the actual line would cut. Even when i put the material right under the camera i an be a half inch off easily. How are you aligning your cut line?
It really depends n the material thickness that is set when you’re aligning and how close to the camera you’re piece is positioned…
One of the annoying things (only because I got bit yesterday ) is that if you draw on a 1/4 inch thick piece, scan and cut thinking you’ll be “right there” it can easily be off a larger distance than the 1/4 advertised. As you see below, the cut is a full 1/2 inch off the drawn line.
