Forge objects in Halo: Reach/Structure

From Halopedia, the Halo wiki

This article contains details objects in the Structure category placeable in Forge mode in Halo Reach. For objects in other categories, please see one of the pages listed below.

The format of this page differs from the other pages listing Forge objects due to the Structure category only applying to a small number of maps, and including a very large number of parts.

Objects in the same section share a common part limit. Placing one reduces the number remaining for all the others in the same grouping.

Door, Double
Window, Double

Wall, Coliseum
Very, very large and flat, relatively few of these can be used to create a large section of wall or floor. However, not the most aesthetically pleasing part when used to construct most of a map.
Window, Coliseum
The perfect shape to plug the entrance/exit to The Coliseum area on Forge World. One can also fit in the depression at the back of the chamber. Not quite as large as a Wall, Coliseum, however when used to wall off an area it makes it look less like a solid concrete bunker due to the large panes of glass.
