    A new way forming the arc is created following the order of the nodes' selection.

  2. One way selected:

    screenshot 3 screenshot 4

    The arc is "fused" into the selected way between its' last three nodes using these three nodes to specify the arc.

  3. One way and three of its' nodes selected:

    screenshot 5 screenshot 6

    The arc is "fused" into the selected way between the three selected nodes using them to specifiy the arc.


  • If multiple ways share the nodes under 2. or 3., those ways are modified, too.
  • Currently the middle node is moved, proportionally distributing the nodes in the arc.
