Provides access to members that identify geometric objects that can have 3D coordinates and defines operations on such objects. Note: the IZ interface has been superseded by IZ2. Please consider using the more recent version.
IZ contains methods for setting Zs through interpolation based on existing Z values, Z values set at the From and To Points, and Z values from a FunctionalSurface. Z values may also be set to a single constant value. IZ also contains a method for determining if consecutive vertices exhibit a vertical relation.
