An infill defines the contents of a door/window assembly cell. A door/window assembly cell can have the default simple panel or contain a nested grid, an AEC Polygon, curtain wall unit, door or window style. The object styles you use in infills must exist in the current drawing to be added to an infill definition. Panels typically represent glazing or other plain cladding, such as stone or concrete.
Specifying Door/Window Assembly infill definitions
Cell Assignments
A cell assignment defines the infill definition used for cells. You can use one cell assignment to assign the same infill to all cells, or you can create multiple cell assignments to assign different infills to different cells.
Do not assign multiple definitions to the same cell. If you do, the last definition assigned to the cell is used.
Default Cell Assignment
The default cell assignment is used by all unassigned cells. You can modify the default assignment to be any type of infill, but you cannot delete the default cell assignment.
You may want to modify the default cell assignment to use the infill definition that occurs most frequently in your design. Any cells not assigned to other infills then use this infill definition.
Materials and Display Properties of Infills
The layer, color, linetype, and other display properties of the default infill are applied to all infills unless you assign materials to the infills you created or you create a custom display component for each definition. Then you can control the display of each infill definition independently.
