To Remove Mullions From a Curtain Wall Unit Grid

Use this procedure to remove a mullion from the curtain wall unit. You can create a mullion definition whose edge width and depth are zero. Adjacent infills expand to fill in the space that was occupied by the mullion. This is an effective way to represent butt glazing.
