Aligning shapes

You can align shapes by their left, right, or center vertically or by their top, bottom, or middle horizontally in Unified Modeling Language (UML) diagrams.

Tip: Selected shapes align to the shape that you select last and that has filled sizing handles. Grouped shapes (that are selected by the Marquee selection tool) are aligned by the boundary of the group, not by the individual shapes in the group.
To align shapes:
  1. In the diagram editor, select the shapes that you want to align.
  2. Click Diagram > Align and click a type of alignment.
