To modify an instance property of a window, you change the value of the corresponding parameter, as described under Modifying Instance Properties.
Common instance properties for walls are described below.
| 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. |
| Phasing | |
| Phase Created | Specifies the phase when this instance was created. See Creating Phases. |
| Phase Demolished | Specifies the phase when this instance was demolished. See 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. |
