Assigned door/window assembly infill Both curtain wall units and door/window assemblies can reduce the need for nested grids, making edits to the curtain wall easier. Elements of Grids Grids are the foundation of curtain walls, curtain wall units, and door/window assemblies. Every grid has four element types: ■ Divisions: Define the direction of the grid (horizontal or vertical) and the number of cells ■ Cell Infills: Contain another grid, a panel infill, or an object such as a window or a door ■ Frames: Define the edge around the outside of the primary grid and nested grids ■ Mullions: Define the edges between the cells NOTE Division is an abstract element, in contrast to the other three element types that represent physical elements of the curtain wall. Each element type is assigned a default definition that describes what elements of that type look like. Element type Divisions Cell Infills Frames Mullions Default definitions Primary horizontal grid with a fixed cell dimension of 13' and secondary vertical grid with a fixed cell dimension of 3' Cells containing simple panels 2" thick Left, right, top, and bottom outer edges of grid 3" wide and 3" deep Edges between cells 1" wide and 3" deep Specifying grid element types You can create new element definitions and assign those definitions within the curtain wall. For example, you can create multiple infill definitions, and then assign different infills to specific cells in the grid. Curtain Walls | 751
