Moving faces radially

Question

I would like to move faces radially, but for some reason they don't want that. When I move the faces, I expected them relatively to the middle / radially. But as one can see from the screenshot, they move... ermhhh, differently. One the face with the white circle moves as I expected.

Can anybody tell me how to achieve a radial movement?

in object mode have you applied scale and rotation? (Ctrl+A) — , Aug 25 '15 at 15:20

Ensure that the Pivot Point is set to '3D Cursor'.
In edit mode, select the faces you want to move radially.
Hit 'Shift-S', then select 'Cursor to Selected'. The 3D Cursor should now be in the center of your selected faces.
Hit 'S' then 'Shift+Z'. This will scale your faces in X and Y but not Z.
Move your mouse or enter a value from the keyboard and hit enter when the faces have been moved radially to the correct position.

Can you also tell me how this would work for rotating the faces shown in the screenshots? I would like to have the facing downwards, but that gives me the same problems as my initial problem, but 'R' then Shift+Z won't fix it for me. – tmighty Aug 25 '15 at 17:50
You may want to ask a separate question for this, but... Enter edge mode, select just the top edges of those faces you want to face downward. Then hit Shift+S, Cursor to Selected, then 'S' and move your mouse. Should work. – Mike Metcalf Aug 25 '15 at 17:53

Shrink Fatten. Keyboard Alt-S. Move Selected vertices along the geometric surface normal.

You're looking for Shrink/Fatten operation. This will move selected faces or vertices along their own surface normals.

To do so, select your faces or vertices and hit ALT+S.

If you leave my original text unaltered first you are welcome to add your verbiage after mine. 10 sentence maximum, since I see 5 bullet points in another response. Then I can see how your verbiage has some value in this somewhat uncomplicated request from the original poster of the question. There is the official invitation. @Polosson – atomicbezierslinger Aug 25 '15 at 16:44
done. It's not highly relevant modification, but tries to be more human readable. Without wanting to be unkind, of course. Cheers! – Polosson Aug 25 '15 at 17:03
What an amazing improvement! I am staggered and textless. – atomicbezierslinger Aug 25 '15 at 17:06
Thank you, that does what I want in this special case, but I would like a more generic approach, thus I think I will try out the 3D cursor. – tmighty Aug 25 '15 at 17:12

Perhaps you want to scale them with the pivot point set to the object's center?

If this causes them to move in the Z direction you have two alternatives to compensate:

g z to adjust their position afterward.
use the 3D cursor as a pivot point after you copy it from the object origin, and then adjust its Z before scaling the faces.
