Hello,
What tools have people found the most useful for smoothing vertices on a SubD model? I’m finding when there are a lot of vertices keeping wobbles out of the surface is difficult. Also, what tools are best to move the vertices? I like moveUVN for Nurbs Vertices, but don’t know if there is an equivalent for SubD. I’ve been using the gumball with world orientation axis to move the vertices, which doesn’t provide the same level of control.
fastest way to get rid of wobbles is to delete edges until the shape falls apart and then undo the last edge you deleted.
rule of three- keep all transitions as simple as you possibly can
you can also use gumball to “scale” points to smooth them.
select points, relocate gumball to the center of where you want to smooth to and then use scale handles.
also, model in box mode, refine in smooth mode.
you can see all sorts of wobbles very very clearly in box mode that are easy to straighten out that are hard to see and adjust in smooth mode.
MoveUVN works on Sub-D control points (F10 to turn them on), so there’s that. There’s also Smooth, which works on Sub-D control points. Also I tend to often simply delete the wobbly faces, then use Bridge to create a clean transition and Stitch to “re-join” the edges, letting the edges of the newly created bridge set the Stitch Location - see video for a very simple (and purposely constructed) example.
I find relocate gumball a pain to use regularly, especially when the relocated gumball is lost the moment you de-select the object. Wish the relocate was persistent.
Using Scale and SetPt to even things out:
Great suggestions! Thank you all for the input 
you know you can hot key that yes? In v9 you can even single hotkey it.. This really supercharges gumball IMO.
with osnaps and snappy gumball I find it very easy to use.
for entire object objects (or subd faces) if you toggle auto reset gumball off the gumball does stay relocated.
sadly it does not do so for cv’s- this is on our list of things to tune up.
This can’t be stressed enough, as a rule of thumb: the model must look good in box mode for it to work great in smooth mode.
It’s the only way to have full control over how the surface flows, at least in the beginning until SubD becomes second nature.
Box mode is the 3D equivalent to a SubD as a nurbs curve controlpoints are to a nurbs surface.
Shit in = shit out 
And any shortcuts you do in the beginning will have to be payed back in finetuning later.
(But when sketching ignore all rules until you get the correct shape, then remodell. That is often faster than being too OCD on a volume test)
