Can't you gang two double casements? (Actually, one of the double casements would be a W Casement 1 window without the transom, to get the fixed/operable effect. See help menu on ganging windows.)

Thanks Richard. I see that but I need to have one marker for the multiple sections to represent it as one unit. The gang still have separate marker. I did a long way but look like it works for now by having one opening of that size and draw the rest in 2d....<sigh>
