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. |
| 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 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. |

| 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. |
