Automatic reorganization
The authorization diagram, class diagram, collaboration diagram, components diagram and the relational diagram all have the automatic drawing reorganization functionality.

The automatic drawing reorganization functionality is automatically enabled on loading a diagram that does not yet include a drawing.
To modify organization of an existing drawing:
1. Select Drawing > Reorganize Drawing.
2. Select the desired reorganization mode, the direction and the style of links in the diagram.

The miniature image alongside the reorganization options gives you a view of each type of reorganization.
3. Click OK to apply the modifications.
