Specifying Offsets for the Mullions of a Door and Window Assembly
Use this procedure to define mullions that are offset from the start or end of the door/window assembly to lengthen
or shorten the edge or offset in the X or Y direction to shift the edge. For example, you might want to represent butt
glazing by offsetting the mullions to be behind glass panel infills.

Removing a Mullion Definition from a Door and Window Assembly Style
Use this procedure to remove a mullion definition that you no longer need. You cannot remove a mullion definition
if it is assigned to a mullion, but you can remove it if it is assigned as an override to a mullion. Also, you cannot remove
the Default Mullion definition, but you can modify it as needed.
NOTE For information about removing mullions from between cells, see
Assembly Grid" on page 948.

Description
For vertical mullions, a positive X offset moves the mullions toward
the end of the door/window assembly, while a negative X offset
moves the mullions toward the start of the door/window assembly.
For horizontal mullions, a positive X offset moves the mullions toward
the top of the door/window assembly, while a negative X offset
moves the mullions toward the bottom of the door/window assembly.
In Plan view, a positive Y offset moves the mullions above the
baseline, while a negative Y offset moves the mullions below the
baseline.
Negative Start offset lengthens the mullions beyond the start point,
while a positive Start offset shortens the mullions.
Negative End offset lengthens the mullions beyond the end point,
while a positive End offset shortens the mullions.
