You can specify a curtain element layout for walls, sloped glazing, and curtain systems.
By specifying the layout by type, you can place many instances that already have panels, grids, and mullions on them.
You create a curtain grid layout by specifying a combination of type and instance parameters that affect the faces of the curtain element, as follows:
| 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 left border. |
| Border 2 Type | Specifies the mullion family for horizontal mullions on the right border. |
| Instance Properties | |
| Name | Description |
|
Vertical Grid Pattern Note: These parameter descriptions apply to the Horizontal Grid Pattern instance parameters also.
|
|
| Number | If Layout (under Vertical Grid Pattern) is set to Fixed Number, enter the number of curtain grids for the curtain instance. The maximum value is 200. |
| Justification | Determines the spacing of grids along the curtain element face, when grid spacing does not divide evenly into the face length value. Justification also determines which grid lines are first removed or added when the number of grid lines changes 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. If you specify this value for individual faces, no value is displayed 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 5’ for offset, the first grid is placed 5‘ from the beginning of the face. If you specify offset for a face, no value is displayed in this field. |
| Measurement Line (curtain system only) | An imaginary line that defines the point from which to measure grid spacing on faces where grid spacing may not be the same across the length of grid lines. Where grids intersect this line, the distance between the grids is equal to the grid spacing value (for Fixed Distance layouts) or up to the grid spacing value (for Maximum Spacing layouts). Where the grids do not intersect this line, the grids can be placed at values either higher or lower than the value for Spacing. |
