/3/ - 3DCG

How do I make each vertex snap to surface individually?
It's really tiresome to have to go through every single point and snap it after extruding a strip.
Quad Draw in Maya works nicely, but it slows down to a crawl after just a few thousand polygons, so I'd prefer to do it in Blender.
(Shrinkwrap modifier didn't work when I tried it)
