description: >
  Parametric framed wall panel with selectable framed height, module width,
  stud lumber size, stud spacing, and exterior sheathing orientation.
 
dimension_convention:
  nominal_width_ft_means: framed_module_width
  nominal_height_ft_means: framed_panel_height
  description: >
    Module height refers to the framed panel height (bottom plate to top plate).
    Exterior OSB sheathing may extend above the framing and is not included in
    the nominal module height.
 
parameters:
  nominal_width_ft:
    type: float
    unit: ft
    min: 0.2708
    max: 8.0
    default: 4.0
    description: >
      Framed module width. The minimum value (0.2708 ft = 3.25 in) represents the
      smallest meaningful filler wall module that can be defined. This corresponds
      approximately to the width of two studs fastened together and represents an
      extreme lower bound used only for filler conditions between modules. Typical
      wall modules are significantly wider.
 
  nominal_height_ft:
    type: float
    unit: ft
    min: 4.0
    max: 20.0
    default: 9.0
    description: >
      Framed panel height measured from bottom plate to top plate.

    description: >
      Exterior sheathing material for this schema version.
 
  sheathing_side_rule:
