(SCULPT MODE) ADD LATHE TO LASSO TRIM

the lasso trim on sculpt mode can cut something off or create a new mesh ,which is great for block out a base mesh, but the new mesh create from lasso is always look like a BOARD ,what i think is that it can do more , for example, if we can make the lasso rotate to mesh (in 3ds max it's call lathe, in blender it's call screw) ,it will be very nice for making arms ,legs, horn or ball shape. The rotate axis can be easily to calculate from the first point and the last point i think.......
