19.2 Aligning selected nodes

TreeAge Pro includes two options for adjusting the vertical alignment of nodes in a tree. This section deals with the use of the Skip Generation command to make manual adjustments to the vertical alignment of selected nodes. It is also possible to specify that all terminal nodes be vertically aligned automatically; this is covered in a later section: Other tree display preferences.

In many trees, asymmetry in intervening events results in the related nodes not lining up vertically. It is sometimes desirable to force these related nodes to line up, resulting in a more intuitive layout of the tree.

To align a selected node with a node in a different subtree:

• Select a node.

• Choose Node > Skip Generation (or CONTROL + ]).

This will extend the length of the selected node by one node generation and moves the selected node's subtree to the right. In the example below, the Standard treatment:Radiationnode has been extended right by one generation.

Skipping one or more generations can be used to line nodes up vertically — for example, the multiple nodes representing a particular decision, in different paths. To skip more than one generation, simply select the menu command repeatedly.

To reverse the effects on the tree, simply un-skip generations at the node which skips a generation.

To remove an extra generation from the selected node:

• Select a node which is set to skip a generation.

• Choose Node > Unskip Generation (or CONTROL + [).

Skipping generations does not affect calculations.
