Curtain Walls: Advanced Design Techniques

 
The Curtain Wall tool is designed with flexibility in mind. You can use it to generate anything from simple storefronts to highly articulated structural glass façades. In this section, we’ll look at the basic principles and how to extend these principles to create a range of designs. The composition of a curtain wall is divided into four primary elements, shown in Figure 11.21:
  1. The wall and its geometric extents.
  2. Curtain grids.
  3. Mullions.
  4. Curtain panels

The wall A curtain wall is drawn like a basic wall and is available in the Type Selector when the Wall tool is active. It has top and bottom constraints, can be attached to roofs, can have its elevation profile sketch-edited, and is scheduled as a wall type

Curtain grids These are used to lay out a grid that defines the physical divisions of the curtain wall. The layout grid can be designed freely as a combination of horizontal and vertical seg-ments or can be a type with embedded rules that specify regular divisions. Figure 11.22 shows a typical grid division and expressive curtain panels in between

Mullions These represent the metal profiles on a glass façade, and in Revit they follow the geometry of the grid. They can have any shape that is based on a mullion profile family.

Curtain panelsThese fill in the space between gridlines and are always one of the following:
Empty panels No panel is placed between the grids.

Glazed panels These can be made out of different types of glass that can have any color or transparency.

Solid panels and panels with wall types These can take on any geometry you wish and thus create most interesting structures, like the one shown in Figure 11.23.

Wall types as infill From the type selector you can also choose a wall type to fill the space between the gridlines (mullions). All wall types in the project will be available for your selec-tion. Adding a wall type is usually a typical case in office partitions where the lower portion is a parapet wall and glass fills the upper portion of the metal stud wall.
