Opens the Select Borders to Switch dialog to select the borders for your drawing. Choose one or more borders, and then
select OK to return to the Switch Border Dialog.
<Unknown Border> is used for Drawings by Query Manager components and Volume drawing documents, which do not have any border information the first time you open
the Select Borders to Switch dialog. After you switch the border and update the drawings, SmartSketch Drawing Editor preserves the border name and displays it in the Existing Border column on the Switch Border Dialog.
