Remarks
A shape that does not lie in this one's plane is refused rather than projected in, because projecting would report two plates a metre apart as overlapping and say nothing about it. SharesPlaneWith(GeoPlane3) asks the question beforehand. Everything comes back as GeoFace3, because joining two areas can leave a hole in the middle and only a face can hold one.
Constructors
- GeoFace3(GeoPolygon3)
Initializes a face with no holes.
- GeoFace3(GeoPolygon3, IEnumerable<GeoPolygon3>)
Initializes a face with holes.
- GeoFace3(GeoPolygon3, IEnumerable<GeoPolygon3>, Tolerance)

Properties
- Area
Gets the area of the face, with the area of every hole removed.
- Boundary
Gets the outer boundary of the face.
- Centroid
Gets the centroid of the face: the centroid of its boundary with its holes taken out, so a plate balances at this point whatever has been cut from it.
- Holes
Gets the read-only list of holes cut out of the face, each wound the same way as the boundary.
- Normal
Gets the unit normal of the face, taken from its boundary.
