Displays with a solid fill or hatch fill style. The region is defined by a single outer shape and can contain multiple inner shapes that define holes in the region. Boundary2d objects can be created using the methods on the Boundaries2d collection object. The geometry of the Boundary2d object can be driven by a list of related linear geometrical elements (such as lines, arcs, and circles) that define a closed region. The BoundingObjects2d collection object provides access to the related linear geometrical elements. The Boundary2d display is controlled by a Fill Style that can provide a solid fill or a hatch fill. The display characteristics of a Boundary2d object can be overridden using the methods and properties on the BoundaryStyle2d object.
