Why can't I adjust proportional size? I am new to blender and am trying to grab only a part of the mesh and move it with the sphere tool for the falloff. I read that you press g and scroll up and down to make the scope bigger/smaller so you don't move the entire mesh, but when I do that, a dotted yellow line and square appear instead and the whole mesh starts rapidly moving around.



I would really appreciate some help on this, it's driving me insane!
You have to select proportional editing first(at the bottom the 3d view), then hit g to grab.
