Window Instance Properties

Modify instance properties to change a window's level, sill height, head height, and more.

To change instance properties, select the element and change its properties on the Properties palette.

Name Description
Constraints
Level Indicates the level on which this instance is placed.
Sill Height Specifies the height of the sill in relation to the level on which this instance is placed. Changing this value does not change the instance size.
Orientation Select vertical or slanted orientation for a window placed in a slanted wall. When changing a vertical wall that contains inserts (windows, doors) to a slanted wall, the inserts will remain in a vertical orientation and you must adjust their orientation manually using the Orientation Instance property.
Note: After creating a window, deselect the window, click away, and reselect the window to display the parameter. See Troubleshooting: Cannot Find an Instance Parameter.
Note: After placing a window that is oriented vertically in a slanted wall, you must manually resolve the resulting gap between the element and the wall.
Identity Data
Comments Displays a comment that you enter or select from the drop-down list. Once entered, a comment can be selected for other instances of elements in the same category, regardless of type or family.
Mark Enumerates instances within a category by increasing this value by 1 for each instance placed. For example, the first window you place in a project will have a Mark value of 1 by default. The next window you place, regardless of type, will have a Mark value of 2. If you change this value to one that is already used by another window, Revit LT warns you, but allows you to continue using it. The Mark property of the next window you place will then be assigned the next highest unused number.
Phasing
Phase Created Specifies the phase when this instance was created. See Create a phase.
Phase Demolished Specifies the phase when this instance was demolished. See About Demolishing Elements.
Other
Head Height Specifies the height of the top of the instance in relation to the level on which the instance is placed. Changing this value does not change the instance size.
