SignedDistanceTo(GeoPoint2)
Calculates the distance from this face to a point, negative for a point on the material.

Remarks
The magnitude is the distance to the boundary, whichever side of it the point is on, and the sign says which side: negative on the material, nought on an edge, positive off it. DistanceTo(GeoPoint2) reads the face as filled and so answers nothing at all for a point on the material, which is the one place the two part company. The boundary of a face is its outline and the rim of every hole, so a point in a hole is off the material.
SignedDistanceTo(GeoPoint2, Tolerance)
Calculates the distance from this face to a point, negative for a point on the material, within a tolerance.
