Illustrator CS 6: can I give a gradient Mesh no fill while I'm building it.
So far I've been dealing with this by setting the transparency to 10% or something. This works but it would be so much simpler if I could just apply No Fill to the mesh. The Fill / Stroke options at the top are missing and the No Fill option from the Tool Bar don't work and neither from the Swatches pallet.
