Defining Door and Window Assembly Mullions
All door/window assembly grids, including the primary grid, can have mullion definitions. The mullions of a
door/window assembly are the edges between the grid cells. You can define the mullions by specifying a width and
depth or by selecting a profile from which the mullion is extruded.
Because door/window assemblies can contain multiple nested grids with different mullions, it is helpful to use a naming
convention for grid mullions that indicates the grid location or purpose within the door/window assembly. For example,
L3-FL1- Window Mullion identifies a mullion for a window in a third-level grid on Floor 1.
Specifying default and profile-based Door/Window Assembly mullions
You create mullion definitions for a specific door/window assembly style and those definitions can be assigned only
to mullions in door/window assemblies of that style. You can create as many mullion definitions as you want and then
assign the definitions to mullions as needed. If you have nested grids, each grid has its own mullions. A default mullion
definition, which you can modify and assign as needed, is used for any unassigned mullions. For more information,
see Assigning Definitions to the Mullions of a Door and Window
TIP Using Style Manager, you can copy a frame definition and use it as a mullion definition. Select the frame definition and
drag it to Mullions in the left pane.
Materials and Display Properties for Mullions
If you do not use materials to control the display properties of mullions, you can specify their display properties in the
door/window assembly style. The layer, color, linetype, and other display properties of the default mullion are applied
to all mullions unless you create a custom display component for each definition. You can then control the display of
each mullion definition independently. For more information, see
Assemblies" on page 950.
Defining Door and Window Assembly Mullions by Width and Depth
Use this procedure to define mullions by specifying a width and a depth.
Because door/window assemblies can contain multiple nested grids with different mullions, it is helpful to use a naming
convention for grid mullions that indicates the grid location or purpose within the door/window assembly. For example,
L3-FL1- Window Mullion identifies a mullion for a window in a third-level grid on Floor 1.
