Any of the below two cases happening to you?:
After dragging one of the intermediate nodes on the sides of the Ceiling Editor object, the Number of editable nodes per edge field will become disabled for the edited Ceiling object, indicating that you cannot make changes to the number of available nodes from this point.
After the Ceiling is placed using the Interior Wizard, the Number of editable nodes per edge field will become disabled since this fields does not apply in case of Ceiling objects placed using the Interior Wizard.
About the Move Node command:
Ceiling Objects placed with the Interior Wizard do not have the Move Node command available in the Pet Palette since their geometry is bound to the geometry of the Zone. You change the Zone's Geometry and then update the Ceiling Object's geometry using the Design\Design Extras\Interior Wizard\Update Room Accessories menu command.
