Description
-----------
This sample demonstrates manipulating balloon and centering dimensions.  It renumbers balloons so they're in order, either CW or CCW around the view.  It also arranges the balloons so they're aligned either vertically or horizontally and optionally are evenly spaced.

The dimension part of the sample centers all dimensions on the sheet.

Instructions

For aligning, select a balloon that will be the one that defines the alignment position and continue to select other balloons to align to it.  Choose vertical or horizontal alignments and optionally, select the "Evenly Spaced" checkbox and then click the "Align" button.

For renumbering, choose Clockwise or Counterclockwise and clicke the "Renumber" button. Select the balloon that will be number "1".
