Type-Driven Curtain Element Layout Type Properties

Modify type properties to change the construction, grid pattern, and mullions for the family of the selected curtain element.

To change type properties, select an element and click Modify tabProperties panel (Type Properties). Changes to type properties apply to all instances in the project.

Type Properties
Name	Description
Construction
Automatically Embed (curtain walls only)	Determines whether the curtain wall embeds into other walls.
Curtain Panel	Specifies the curtain panel family type for the curtain element.
Join Condition	Controls which mullions break at intersections on a curtain element type. For example, use this parameter to make all horizontal or vertical mullions on a curtain wall continuous, or to make mullions on grid 1 or grid 2 continuous on sloped glazing.
Vertical Grid Pattern (for curtain walls) or Grid 1 Pattern (for curtain systems and sloped glazing)
Note: These descriptions apply to the Horizontal Grid Pattern or Grid 2 Pattern.
Layout	Specifies an automatic layout for curtain grid lines along the length of a face on a curtain element. When you specify a value other than None, Revit automatically adds grid lines to the faces of a curtain element. Fixed Distance indicates that the curtain grids are placed at the exact value specified for the Spacing parameter. If the spacing is not an even factor of the length, a space is inserted at one or both ends of the face, depending on the justification parameter. Fixed Number indicates that you can specify different numbers of curtain grids for different curtain instances. See the Number instance property description under Vertical Pattern for more information. Maximum Spacing indicates that the curtain grids are placed at even intervals along the length of the face. The distance can be up to the value specified for Spacing, but is not necessarily at a specified fixed distance.
Spacing	Enabled when Layout is set to Fixed Distance or Maximum Spacing. When the layout is set to a fixed distance, Revit uses the exact value specified for Spacing. When the layout is at a maximum spacing, Revit 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 (for curtain walls) or Grid 1 Mullions (for curtain systems and sloped glazing)
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 (for curtain walls) or Grid 2 Mullions (for curtain systems and sloped glazing)
Interior Type	Specifies the mullion family for interior horizontal mullions.
Border 1 Type	Specifies the mullion family for horizontal mullions on the bottom border.
Border 2 Type	Specifies the mullion family for horizontal mullions on the top border.
