§Face Regions (created with the Split Face command)
§Face.HasRegions – reports if the face contains regions
§Face.GetRegions() – return a set of region faces
§
§Hermite Spline creation new overload
§NewHermiteSpline(controlePoints, bPerioidic, startTangent, endTangent) - Handles tangency at start and end of spline
§
§PolyLine
§A new geometry object
§Represent a set of points forming contiguous line segments
§Returned from Element.Geometry

| We can now find out if face contains regions that were created with Split Face command and even return the set (or list) of region faces. As the material of these faces can be independently modified through the UI with the Paint tool, the material of each face can be found from its MaterialElementId property.
| Hermite Spline creation has a new overload.
| A new geometry object called PolyLine has been introduced which represents a set of points forming contiguous line segments and is returned from Element.Geometry.
