Moving a shared node without stretching all connected edges (split-move)

When you move a node, all the edges that connect to it are stretched to stay connected to the node. When you move an edge, edge segments stretch to maintain the connection of shared endpoint nodes to their previous location. Sometimes you may want to move a node and a connected edge without stretching the other connected edge. Moving a shared endpoint node of an edge requires you to temporarily split the topological relationship between the node and the other shared edges, then reestablish it. This is known as a split-move of the node.

Steps:
  1. Click the Topology Edit tool Topology Edit Tool on the Topology toolbar.
  2. Click the edge to which you want to move the endpoint node.
  3. Hold down the CTRL key and drag the selection anchor to the place where you want to snap the edge's endpoint node.
  4. Right-click and click Split Edge At Anchor. Splitting the edge creates a new node to which you can snap the endpoint node of the edge.
  5. Click the edge whose endpoint node you want to move.
  6. Hold down the N key and drag a rectangle around the endpoint node you want to move. The N key limits the Topology Edit tool selection to nodes.
  7. Hold down the S key and drag the node that you want to move to the node you created. The S key changes the pointer to the split-move pointer.
  8. Split-move pointer

    The endpoint node of the edge is moved to the new location, and the topology is maintained. If you do not snap the node to the new node or the edge, the split-move is canceled.

    Turn on the option to stretch a feature's geometry proportionally (Editor > Options > General tab) to move all the vertices back to the last node.
