I’ve found there are random glitches when importing SVG files in rhino6 despite import being otherwise fairly stable.
White background with ruler is original illustrator file, white background with frame is showing the SVG being read by OSX’s quick view fine, and gray background is imported SVG in which one or two control points have jumped.
In other, more dense files I’ve found that the same sort of glitch will happen all over the place – more than just once per import.
If you have a SVG file that imports incorrectly into Rhino, please post it here.
If the same file imports correctly into some other application please include those details too.
SVG files are relatively simple so there isn’t much that can go wrong.
