I have a curve (which is a loop) that I am trying to manipulate in edit mode. When I use proportional editing with connected mode, a certain part of the curve is not affected. It only seems to happen between two vertices. On one side they act as expected and on the other side they stay where they are.
I tried converting the curve to a mesh, deleting and the re-adding the vertices that caused the problem, and then converting back to a curve. The same problem occured, but between two different vertices.
If I switch the proportional editing to enabled mode, everything works properly, but I want to know why curves behave this way with connected mode. I assume it's because the curve "ends" somewhere, so even though the loop is closed blender doesn't consider the vertices on the other side connected. I'm unsure though so if anyone knows why this happens or where I could read about it, it would be appreciated.
