Arched Cabinet Help

[LeffDesignTeam]

Hi! I am trying to draw this arched cabinetry but keep getting stuck with how to put the arch doors onto the arched cabinet. I am following the Rabbit Design tutorial on Arched Cabinets but am still stuck. Both the cabinet and doors are windows. I have used the convert to symbol to make them cabinet doors but the dialog box still gives me the Window options when I try to change anything. I've spent significantly more time on this than I would like to admit. Grateful for any guidance/help.
