With the Blend/Gradient Shape tool (W) i can turn a orange square into a green circle or a horizontal line into a vertical line. Beautifull, lots of available effects.
One nice thing is that you can edit and bend the path between the shapes to give them the direction you want, or a smoother movement.
Except if you only traced two open paths. In that case, illustrator assumes you want to build a straight gradient, and shows you no path between.
The only way i've found to actually display that path was to build a 3 strokes gradient, and remove the third stroke.
Is there an option to display that blending path ?
Can we have one by default on any blending, even open path ?
