A ISurface is a 2-dimensional IGeometry object.
A simple Surface may consists of a single patch that is associated with one exterior boundary and 0 or more interior boundaries. A single such Surface patch in 3-dimensional space is isometric to planar Surfaces, by a simple affine rotation matrix that rotates the patch onto the plane z = 0. If the patch is not vertical, the projection onto the same plane is an isomorphism, and can be represented as a linear transformation, i.e. an affine.
Polyhedral Surfaces are formed by stitching together such simple Surfaces patches along their common boundaries. Such polyhedral Surfaces in a 3-dimensional space may not be planar as a whole, depending on the orientation of their planar normals (Reference [1], sections 3.12.9.1, and 3.12.9.3). If all the patches are in alignment (their normals are parallel), then the whole stitched polyhedral surface is co-planar and can be represented as a single patch if it is connected.
The boundary of a simple Surface is the set of closed Curves corresponding to its exterior and interior� boundaries (Reference [1], section 3.12.9.4).
The only instantiable subclasses of ISurface defined in this standard are IPolygon and IPolyhedralSurface. A IPolygon is a simple Surface that is planar. A IPolyhedralSurface is a simple surface, consisting of some number of IPolygon patches or facets. If a IPolyhedralSurface is closed, then it bounds a solid. A IMultiSurface containing a set of closed IPolyhedralSurfaces can be used to represent a ISolid object with holes.
