  Anisotropic aerogel possesses structure which exhibits a strong influence
over the composition and orientation of the order parameter of imbibed
superfluid $^3$He. Computational studies have identified stretched aerogel with
plane-like structures and compressed aerogel with nematic-like structures.
Studies of the B phase of superfluid $^3$He in stretched aerogel display an
enhanced nuclear magnetic susceptibility likely caused by Andreev bound states
near plane-like impurity sites. We report further details on the influence of
these planar structures on both magnetic and orbital orientation transitions.
The orbital orientation transitions appear in both the B and A phases of
stretched and compressed aerogels. These transitions result from a crossover of
the superfluid coherence length with long and short length scale structure with
the coherence length and are consequently magnetic field independent.
Additionally, the apparent temperature-independence of the susceptibility of
the B phase equal to that of the A phase in stretched aerogel, is in marked
contrast with the field dependence of the superfluid A to B phase transition,
indicating that it is a near-isentropic transition.
