Dave,
As Bulia explained, the tweak tool ends up distorting the path, and in a path with few nodes the closer nodes' curvatures will be affected more readily than one with more nodes. However, no matter the size of the object or the amount of nodes, there will be some distortion to the entire object.
Bulia's solution (to use node sculpting with the node tool) may be more along the lines of what you're looking for, but it operates much differently. You'll have to try it to see if it will work for you.

bulia,
Thank you for responding.
However, it seems that I may have not explained my problem clearly.
Tweak tool does not work by moving vertices (i.e. nodes).
I understand that and my use of the word vertices was perhaps misplaced.
Whether it's nodes, or an approximate polygon, or whatever it is the Tweak tool is moving, it's moving too much of it.
Let me try to be more simple. Let's say I have a large roughly circular shape. I want to use the Tweak tool to alter the bottom. As it is now, when I do so, the top of the shape also shifts around, no matter how small the size of the brush.
How can I make localize the Tweak tool's affect to just the area in an around the size of the brush, and not the entire object or path?
