I am also having issues with SCAL changing the size of my SVG files. In my case, though, it is making them smaller.
I am using the exact same process as I had been using the past months, which had been working great for me.
I create a design in SCAL, save it, and then also export it as an SVG. (Having it as an SVG allows me to pull it up in my library, so I can put numerous designs on one page, and cut them all on one sheet.)
However, the designs as an SVG file are not the same size as my my SCAL files. For example, my one design is created to be 12" x 2.5", and I saved it like that as an SVG. However, when I go to open the SVG file, it is 9.5" x 1.875".
It is only doing these to designs that I have created since the update. The ones I did previously are remaining how they were, the SVGs being the same size as my SCALs.
I also checked to see what happens if I use one of the SCAL designs. I opened the heart, made it a 5" size, then saved it as an SVG. When I opened the SVG, it was 4" size. I think this is happening to any SVGs I am creating since the last software update.
I do have a way to work around this problem, mainly using only my SCAL files, and not my SVGs, but it would be most helpful if I could get a solution for this!
Thanks!
