Nesting dimensions

To nest dimensions, in the Dimension Controller dialog box, drag an off-grid dimension and drop it into the across or down area. For across dimensions, drop it above or below an existing dimension. For down dimensions, drop it to the left or right of an existing dimension. The vertical line preceding or following the on-grid dimension tile is highlighted.

You can remove a nested dimension by dragging the nested dimension and dropping it on top of a gray area below the dimension list.
