About the Function of Walls, Floors, and Building Pads for gbXML Export

When you export analytical surfaces to gbXML, the Function type parameter affects walls, floors, and building pads as follows.

Exterior surfaces

If a wall has 2 adjacent spaces and its function is Exterior, Foundation, Retaining, or Soffit, the wall is displayed as an interior surface. If the wall has one adjacent space, it is displayed as an exterior surface.

Note: If the wall is located below the ground plane, it is displayed as an underground surface, regardless of function.

Interior surfaces

If its function is Interior or Core Shaft, a wall is displayed as an interior surface, regardless of the number of adjacent spaces.

Slab surfaces

If its function is Exterior, a floor or building pad is displayed as a slab surface.

Note: If a surface is located below the ground plane and is adjacent to one space and earth, the surface should be an underground surface, regardless of its function.

Floor surfaces

If its function is Interior, a floor or building pad is displayed as a floor surface.

Shading surfaces

If its function is Exterior, Foundation, Retaining, or Soffit, a wall, floor, or building pad creates shading surfaces.

If its function is Interior or Core Shaft, a wall, floor, or building pad does not create any shading surfaces.
