Element definitions determine the appearance of the four basic curtain wall unit elements. There is a different definition type for each element.
| Element type | Default definitions |
|---|---|
| Divisions | Horizontal grid with two manual divisions offset from the top and the bottom of the grid |
| Cell Infills | Cells containing simple panels |
| Frames | Left, right, top, and bottom outer edges of grid 3" wide and 3" deep |
| Mullions | Edges between cells 1" wide and 3" deep |
Each type of element can have multiple definitions. For example, you can define a division to create a horizontal grid or a vertical grid, and you can define the cells to contain a nested grid or a panel infill. To make reuse easier, you can save the element definitions, and then assign them to grids, cells, frames, or mullions as needed.
Element definitions are style-specific. When you create element definitions for a specific curtain wall unit style, those definitions are available only for curtain wall units of that style. For example, if you define a panel infill for one curtain wall unit style, that infill is not available as an option when you edit a curtain wall unit of a different style.
