Edit Network

This command modifies an existing network.

1. Modify network: move, select, delete nodes or change edge type.

   1. Select nodes and edges and delete them by pressing Delete or Backspace.

   2. Double-click to replace a straight edge by a curved one, or a curved edge by a straight one.

   3. Click and drag nodes to move them. When a node is moved, all attached edges are also modified. S traight edges stay straight, and curved edges stay curved.

2. Create new edge: add a new edge. When this option is activated, you have the possibility to create a new edge by clicking the extremities on existing nodes or edges.

   1. If you click on an existing edge, press Alt to keep the exact clicked point as extremity, else the extremity will be created on the closest point (between the 2 nodes or the middle of the clicked edge).

   2. If you want a straight edge (by default, color is the same as polyline), click only the 2 extremities. The created edge will be projected on the mesh, and added to the current network.

   3. If you want a curved edge (by default, the color is the same as bspline), click the first extremity + points on the mesh + the second extremity. The curved edge is displayed in blue, control points are displayed in red. Once the second extremity has been clicked, you have the possibility to adjust the edge with the control points. Click Enter when the edge has been correctly adjusted. The edge will be projected on the mesh, and added to the current network.
