Simple Primary Grids
When you nest grids, you start with one primary grid. Each cell in the primary grid can then be filled with another
grid. For example, if your primary grid is horizontal and has three cells, you can nest a vertical grid in each horizontal
cell to create a simple two-dimensional (2D) grid. This is the nesting configuration for the Standard curtain wall style.
Specifying cell division definitions 1
The previous illustration shows all cells in the grid with the same cell assignment—a vertical division. However, each
cell in a grid is independent and can have a separate assignment. For example, the following illustration shows a three
cell horizontal grid with different assignments in each cell. The bottom cell contains another horizontal division, the
middle cell contains vertical divisions of varying width, and the top cell contains a vertical divisions of a fixed width.

Multiple Nested Grids
You can continue to nest grids to create multiple levels. For example, the following illustrations show the Standard
curtain wall style, which is a simple two-dimensional (2D) grid, with one horizontal cell and three vertical cells. Another
grid is nested in the first cell of the secondary grid. This creates a tertiary grid. The final illustration shows the nested
grids assigned to all cells.

Defining Nested Grids
You can define nested grids by using the Design Rules tab of the Curtain Wall Style Properties dialog box. The tree in
the left pane lists the grids. There is always one primary grid. The primary grid can have one or more secondary grids.
Each secondary grid can have one or more tertiary grids, and so on.
TIP To quickly create nested grids in all cells, change the default cell assignment to Nested Grid. If you want multiple levels
of nesting, be sure to change the default cell assignment for each grid. For more information, see
“ Creating a Nested Grid
in a Curtain Wall ” on page 788 .
Each grid has its own cell assignments. You assign cells to contain another grid, a panel infill, or an object such as a
door or window. For more information, see “
Assigning Infills to Curtain Wall Cells ” on page 786.
