Options Bar Part of the Revit interface that provides context-sensitive settings and functions, depending
on the tool currently in use. In the Revit window, the Options Bar is located below the ribbon and above
the drawing area.
See Using the Revit Interface on page 85 and Options Bar on page 99.
orientation The state of being aligned with (or facing the same direction as) a particular item or direction.
For example, in Revit Architecture you can change the orientation of a view to True North, or you can change
the orientation of a compound wall to reverse the order of its layers.
origin A fixed starting point, or the point in a coordinate system where the axes intersect.
In Revit Architecture, you use an origin for many functions, such as positioning a linked project, creating
a custom fill pattern, positioning a group, resizing walls, or sketching lines for a new family.
The origin of each element is defined in the family file for the element. When you place an element in a
project, Revit Architecture uses the origin defined for the selected family type when snapping to snap points
and lines.
