Add Mullions to a Curtain System

After creating a curtain system, place mullions along grid lines.

1. Click Architecture tabBuild panel (Mullion).
2. Highlight the grid line to which to add the mullions, and click to select it.
   Tip: Hold Shift to place a mullion only on the selected segment. Or hold Ctrl to place mullions on all open grid segments.

   The mullion is sized to the grid line, and is split at intersections with mullions.

   You can change the properties of mullions.
