Manually Defining the Number and Size of Cells in a Curtain Wall Unit Grid
Use this procedure to manually add gridlines and specify an offset for each one when you need to create a unique grid
that does not fit into any of the other division types. You can also start with a fixed cell dimension grid or a fixed
number of cells grid, and then manually adjust the grid lines to suit your needs.
1 On the Format menu, click Style Manager.
2 Expand Architectural Objects, and expand Curtain Wall Unit Styles.
3 Select a curtain wall unit style.
4 Click the Design Rules tab.
5 In the left pane, select Divisions under Element Definitions.
6 Select a Division definition or create a new one.
7 Select Manual for Division Type.
8 Click the Add Gridline icon to insert a grid line. Insert as many grid lines as you need. If you need to remove
a grid line, select it from the table and click the Remove Gridline icon.
9 Under Offset in the gridline table, specify an offset distance for each grid line.

10 Under From in the grid line table, select the grid location from which the grid line is offset.

11 To specify an offset for the grid, enter an offset distance for Start Offset or End Offset.
For more information, see “ Specifying an Offset for a Curtain Wall Unit Grid ” on page 851.
12 Click OK.
For information about assigning the division definition to a specific grid in your curtain wall, see “ Assigning
a Division to a Curtain Wall Unit Grid ” on page 863.
Specifying an Offset for a Curtain Wall Unit Grid
By default, grids cells are measured from the start and end points of the curtain wall unit baseline. The width of the
grid frame is not considered in calculating the size of the cell. For example, if you draw a curtain wall unit with a 14'
baseline and a 1' frame on the left and right, and you specify a fixed number of vertical cells, the cells do not appear
equal in size. The first and last cells appear smaller because they include the frame. To make the cells equal in size,
offset the start and end of the grid by the width of the frame.
