- Shrink/Fatten for bevelled curves
This is a much faster and easier way to give a bevelled curve a taper, without using taper curves. Each point on a curve now has a 'radius' value that you can shrink and fatten using Alt S, which will influence the taper when the curve is bevelled (either with a bevob, or with front/back turned off and a bevel dept set). Alt S shrinks and fattens the selected points in an interactive transform, and you can set an absolute radius for selected points with 'Set Radius' in the curve specials menu.
This can be a quick way to create revolved surfaces (eg. http://mke3.net/blender/etc/wineglass-h264.mov )
