Parameter names, values, and descriptions for curtain walls. Values are modifiable.

Curtain Wall Type Properties

Name Description
Construction
Function Indicates the purpose of a wall: exterior, interior, retaining, foundation, soffit, or core-shaft. Function can be used in scheduling and to create filters that simplify a model when exporting.
Automatically Embed Indicates whether the curtain wall automatically embeds into the wall.
Curtain Panel Sets the curtain panel family type for the curtain element.
Join Condition Controls which mullions break at intersections on a curtain element type. For example, this parameter makes all horizontal or vertical mullions on a curtain wall continuous, or it can make mullions on Grid 1 or Grid 2 continuous on a curtain system or sloped glazing.
Vertical/Horizontal Grid Pattern
Layout Sets an automatic vertical/horizontal layout for curtain grid lines along the length of a curtain wall. When set to a value other than None, Revit Architecture automatically adds vertical/horizontal grid lines to a curtain wall. Fixed Distance indicates that the curtain grids are placed at the exact value specified for Vertical/Horizontal Spacing. If the spacing is not an even factor of the wall's length, Revit Architecture inserts space at one or both ends of the wall, depending on the justification parameter. For example, if the wall is 46 feet and the vertical spacing is 5 feet and the justification is set to beginning, Revit Architecture adds 1 foot from the beginning of the wall before placing the first grid. See the Vertical/Horizontal Justification instance property description for more information on justification. Fixed Number indicates that you can set different numbers of curtain grids for different curtain wall instances. See the Vertical/Horizontal Number instance property description for more information. Maximum Spacing indicates that the curtain grids are placed at even intervals along the length of the curtain wall at a distance up to the value specified for Vertical/Horizontal Spacing.
Spacing Enabled when Layout is set to Fixed Distance or Maximum Spacing. When the layout is set to a fixed distance, Revit Architecture uses the exact value for Spacing. When the layout is at a maximum spacing, Revit Architecture uses up to the specified value to lay out the grids.
Adjust for Mullion Size Adjusts the position of type-driven gridlines to ensure that curtain panels are of equal size, whenever possible. Sometimes when mullions are placed, particularly on borders of curtain hosts, it can result in panels of unequal size, even if the Layout is set to Fixed Distance.
Vertical Mullions
Interior Type Specifies the mullion family for interior vertical mullions.
Border 1 Type Specifies the mullion family for vertical mullions on the left border.
Border 2 Type Specifies the mullion family for vertical mullions on the right border.
Horizontal Mullions
Interior Type Specifies the mullion family for interior horizontal mullions.
Border 1 Type Specifies the mullion family for horizontal mullions on the left border.
Border 2 Type Specifies the mullion family for horizontal mullions on the right border.
Identity Data
Keynote Add or edit the curtain wall keynote. Click in the value box to open the Keynotes dialog. See Keynotes.
Model The model type for the curtain wall. May not be applicable.
Manufacturer Manufacturer for the stair materials. May not be applicable.
Type Comments Specific comments on the curtain wall type.
URL A link to a web page for the manufacturer or other appropriate link.
Description A description for the curtain wall.
Assembly Description Description of the assembly based on the assembly code selection.
Assembly Code Uniformat assembly code selected from hierarchical list.
Type Mark A value to designate the particular curtain wall. Useful if you need to identify more than one curtain wall. This value must be unique for each curtain wall in a project. Revit Architecture 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.)
Fire Rating The fire rating of the curtain wall.
Cost Material cost.

Curtain Wall Instance Properties

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 Architecture 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 Architecture 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 Architecture 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.
