Deleting Dangling DAG Nodes

Use this tool to clean up your model by searching for and deleting any DAG nodes that contain no model information.

Deletes null (dangling) DAG nodes that have no objects linked to them. It also deletes empty animation clusters.

Some functions that produce null DAG nodes and empty clusters include:

• Delete > Del objects and Delete > Del active

• Edit > Group and Edit > Ungroup

You can identify null DAG nodes in either of the following ways:

• In the SBD window, they appear as brown rectangles with nothing appearing underneath them.

• In the Information window (Windows > Information > Information window), they have no Geometry section.

For more information on clusters, see the Animating in Alias manual.

You can identify empty clusters in either of the following ways:

• In the SBD window, pick the node above the cluster. If no other node or geometry box is highlighted with a pale blue rectangle drawn inside it, the cluster is empty.

• In the Cluster Editor (Windows > Edit > Clusters).

How to Use

1

Select Delete > Del null nodes- to specify whether you want to delete null nodes or empty clusters, and then click Go.

2

A confirmation box is displayed asking if you want to proceed.

To go ahead with the deletion, click YES or type the letter y. The entire DAG is scanned and any null DAG nodes or empty clusters are discarded.

(No action is taken if you click NO or type the letter n.)

Del Null Options

Select Delete > Del null nodes- to display the Del Null Options window.

By default, Null Nodes is selected (and clusters are not affected).

If you select Empty Clusters instead, all empty clusters are deleted.
