hershel, I didn't find this distance radio button.

Fonte, I was not able to get the result I was expecting for. May it isn't possible with that steps or I did something wrong.
As it's very laborious to prepare this object I attached the file, so you can check it correctly.

Anyway, you drove me to reach it by using Tweak/Magnet:
- Tweak mode: Scale;
- Magnet style: Dome;
- Axis Constraints: Radial (only).
then I put the mouse over the centre face (no selection) and dragged the mouse up. The unexpected thing (but, wanted) was the fact of the action be applied on both sides.

The twisted effect was not so difficult to produce by using rotate + [ctrl+d], but I didn't get the result I was expecting for:


Just in case, I'm looking for something like this.
I'm trying other approach and share it soon.
