To change instance properties, select the element and change its properties on the Properties palette.
| Name | Description |
|---|---|
| Constraints | |
| Base Constraint | The base level of the curtain wall. For example, Level 1. |
| Base Offset | Sets the curtain wall's height from its base constraint. This property is available only when the Base Constraint is set to a level. |
| Base is Attached | Indicates whether the base of the curtain wall is attached to another model component, such as a floor. This is a read-only value. |
| Top Constraint | Curtain wall height extends to the value specified in Unconnected Height. |
| Unconnected Height | The height of the curtain wall when it is sketched. |
| Top Offset | Sets the curtain wall's offset from the top level. |
| Top is Attached | Indicates whether the curtain wall top is attached to another model component, such as a roof or ceiling. This is a read-only value. |
| Room Bounding | If selected, the curtain wall is part of a room boundary. If not selected, the curtain wall is not part of a room boundary. This property is read-only before creating a curtain wall. After you draw the wall, you can select it and then modify this property. |
| Related to Mass | Indicates that the element was created from a mass element. This is a read-only value. |
| Vertical/Horizontal Grid Pattern | |
| Number | If Layout (under Vertical/Horizontal Grid Pattern) is set to Fixed Number, enter a value here for the number of curtain grids on the curtain instance. The maximum value is 200. |
| Justification | Determines how Revit adjusts the spacing of grids along the curtain element face, when the grid spacing does not divide evenly into the length of the face. Justification also determines which gridlines are first removed or added when gridlines are added or removed because of parameter changes or changes to the size of the face. Beginning adds space to the end of the face before placing the first grid. Center adds an even amount of space at both the beginning and end of the face. End adds space from the beginning of the face before placing the first grid. |
| Angle | Rotates the curtain grids to the specified angle. You can also specify this value for individual faces. If you specify this parameter for a face, then no value displays in this field. Valid values are between 89 and –89. |
| Offset | Starts grid placement at the specified distance from the justification point of the grids. For example, if Justification is specified as Beginning and you enter a value of 5 feet here, Revit places the first grid 5 feet from the beginning of the face. Note that you can also set this value for individual faces. If you specify this parameter for a face, then no value displays in this field. |
| Structural | |
| Structural Usage | Sets the structural usage of the curtain wall. This property is read-only before creating a curtain wall. After you draw the curtain wall, you can select it and then modify this property. |
| Dimensions | |
| Length | The length of the curtain wall. This is a read-only value. |
| Area | The area of the curtain wall. This is a read-only value. |
| Identity Data | |
| Comments | Specific comments about the curtain wall. |
| Mark | Sets a label for the curtain wall. This value must be unique for each curtain wall in a project. Revit warns you if the number is already used but allows you to continue using it. (You can see the warning using the Review Warnings tool. See Reviewing Warning Messages.) |
| Phasing | |
| Phase Created | The phase when the curtain wall was created. |
| Phase Demolished | The phase when the curtain wall was demolished. |
