Several times when I try to add a SVG file to my sign the graphic is just all garbled. I was trying to check the layers and if I hit preview the graphic (the danger part of my sign) disappears. Anyone know why this happens? Is it a corrupt SVG file?
From the looks of it they generated a bad mesh, then tried to simplify (reduce poly count) and ended up with a much worse mesh.
Send them a bug report with the SVG, and try some other software for now.
