I'm going to try this on some scrap. This may just prove to be the answer to the slight variation I'm getting when I carve large signs.
I carved a 22.5" X 33 13/16" the other day and had just a slight variation. The way I have been doing it is in Corel Draw using the power clip feature. I place the original drawing in a rectangle, half the size. I position the half where I want it and export it to a PNG file. To get the other half I just edit the placement of the graphics in the power clip rectangle. I always seem to have some slight variation to overcome. I have learned how to plan for this and make the adjustments to the drawing.
This new method sounds like it is allot easier and I can't wait to try it. Hopefully this weekend I can, if I don't have some work I have to turn out. (you know....the honey do construction list)....<grin>.
Please do write the article. I would like to read a detail of how this works.
