Is it possible to buy extra brushes to illustrator draw? I'd like the pencil brush there is in adobe sketch but I've done 80% already in illustrator draw. Alternatively, can I export the artwork from illustrator draw to sketch?
I'm sorry Draw is not like Sketch in that way; it's not possible to import additional brushes/drawing tools. And, for a little more bad news... the only way to bring Draw content into Sketch is to bring it into an Image Layer (it could be a part of your composition, but it would not be an editable drawing).
