Scaling “non-flat” SVG’s is still a problem in 10. It’s a problem in 9 as well. The issue was brought up here, but no responses. SVG I made in Illustrator not scaling properly in Axure
Seems to happen if the SVG isn’t completely “flat”, has layers. For example, I downloaded the official Apple Pay icon direct from Apple’s website. If you throw that SVG into any other app, it scales fine, but in Axure, once it’s converted to shapes, it bugs out when scaled. Below you can see how Axure converts each shape into it’s own. When you scale it, it messes up the shapes (second screenshot).
