idea #198: Proportional editing by vertices

Description
When you enable proportional editing, you have two options:

1: normal prop. editing.
2: connected vertices.

Proportional editing allows you to edit the vertices within a sphere limit. Can this be extended allowing you to affect the vertices dependant on how many vertices are between them rather than distance?

Can you describe a situation where that would be useful?

I had a couple of models, where (the lips for instance) I couldn't quite get the proportional editing to have a smooth effect without altering other vertices which were closer than it.

Basically, the sphere boundary was touching vertices it shouldn't before it could reach the ones I wanted.

The distance along the edges between the vertices could be taken into account too, it's just that all pervading sphere.

In tricky cases like this, you can always select what you want to modify and hide the rest.

Although, I'm not quite sure I understand the situation you're describing and why connected doesn't already solve the problem.

Could you upload an image or the blend file somewhere?

Theeth,

A really simple visualization of this problem is a spiral string: Grab the innermost point of the spiral and translate it to some distant spot. Begin increasing the PET falloff and you will see that instead of picking the spiral up like picking up a string off the floor it will start to grab physically adjacent rings.

The magnets in Wings are more like what this user is requesting, and I have had this same problem as well.... usually with 'u-shaped' things however. It has also bothered me when tweaking the position of something like fingers on a hand, ect...

Cheers

another point with prop.-edit: imagine you want to move a lip, but not the upper and lower together. so if you chose "only connected vertices" it should be possible to either say "all vertices connected to the selected one" or "only vertices that are already connected with the selected one within the radius of the prop.-edit"

you understand?
