 25            <!-- Next, each Arch group includes a horizontal box spanning the two columns. The box is translated up to the top of the columns using a Transform group node. -->
 26            <!-- The angled top of each Arch is created using two boxes, each rotated about the Z axis to tilt them. A translation then positions the tilted boxes at the top of the archway. -->
 27            <!-- Next, the entire Arch group is instanced multiple times, rotating each instance to create a circle of archs forming a gazeebo-like structure. -->
