You can change the size of elements on the diagram as follows:

 

1.Click an element on the diagram. A set of black dots appear at the element's edges.

um_element_waypoints

2.Drag any of the black dots into the direction where you want the element to grow.

 

To reset the element size to its default boundaries, do one of the following:

 

Click the Enable Autosize icon at the lower-right corner of the element.

um_element_autosize

Right-click an element on the diagram, and select Autosize from the context menu.

Select one or more elements. On the Layout menu, click Autosize.

 

When at least two modeling elements are selected on the diagram, they can be aligned in relation to each other (for example, both can be aligned to have the same horizontal or vertical position, or even size). The commands which align or resize elements are available in the Layout menu and in the Layout toolbar.

um_layout_toolbar

When you select several elements, the element that was selected last serves as a template for the subsequent align or resize commands. For example, if you select three class elements and run the Make same width command, then all three will be made as wide as the last class you selected. The element that was selected last always appears with a dashed border.

 

The commands specific to element alignment and resizing are as follows:
