I see there is an import SVG in Easel but how can I import .AI or .EPS files. Is this enen possible with Easel?
You can’t directly, but both formats can be easily converted to .SVG with pretty much any standard vector editing software.
Additionally, I’ve had some good luck converting with some web-based tools such as cloudconvert.com if you don’t happen to have software handy.
If you have illustrator (Which you’d need to work on an .ai file), you can save-as an svg.
