I recently discovered the sketch tool. It is such a great tool! I would really love it if there was a way to use more than one shape/image along the x,y, and z axis', allowing the user to sketch in even more detail, sort of like the lofter in the old 3dstudio 4 (if your familiar with it). Any number of different shapes could be placed along the path of each axis direction. btw I've attached an image of a character that I made using 3d-coat.
