Which option should I use? Do I export it as a png?
What's the best export option in Illustrator to use when making a bottle in the 2D Spinner tool?
All you need for the 2D Spinner tool is the half Silhouetted line of the bottle. Then export that as a .dxf file.
Once inside the 2D Spinner tool simply import your .dxf file and watch the magic happen!
Don't forget to add an interior and Fill!!
