To move a node in the Model or Policy Summary windows, click on it with the left mouse button and drag the node to its desired position. As you move the node, the positioning guide will appear under your cursor to assist you in positioning it. Release the mouse button to place the node in its new position.
When you move a node in the Influence Diagram, any arcs leading into and from the node will be moved automatically. You can move multiple nodes at once by selecting multiple nodes via Ctrl+Click. Release the click and single click one of the selected nodes and drag the group of selected nodes to the desired location. When you move a node in the Decision Tree, its subtree will be moved at the same time. Any branch(es) leading into the node will also shift.
If you want to cancel the move once you've clicked and dragged the node, press Esc and the node will be restored to its original position. If you've already place the node, click the Undo button to restore the node to it's original position.
Stretching a Node: An Alternate Method of Moving a Node in the Decision Tree
There is an alternate means of moving nodes in the Decision Tree. The difference lies in the way the branch that leads into the node you are moving is redrawn. This branch has two relevant pieces: the elbow, or bending point, and the horizontal bar.
With the click-and-drag move command described above, the horizontal bar will change length as you move the node in the horizontal direction; and the elbow will move up or down as you move the node in the vertical direction, but will not move in the horizontal direction.
The alternate method can be done by selecting a node and choosing Stretch from the Context menu. The positioning guide will appear and you can position the node where you want it by clicking the left mouse button to place the node. The difference is that as you move the node, the horizontal bar will remain the same length, while the elbow will move in both the horizontal and vertical directions. This can be useful for making the tree more compact.
