Import SVG

Sketch

This plugin allows you to import SVG as Artboards instead, so that the offset is preserved.
Sketch imports SVG as a Group, but it doesn't support groups that do not fit its content. So if you would have an SVG of 100px*100px with a single centered circle inside of 20px radius, Sketch will create a Group of 40px*40px with a Circle inside.
