1. I don't think that AutoCAD ever uses unnamed ucstablerecords. Are you
looking for Editor.CurrentUserCoordinateSystem?
2. Here's how you get the transform:
UcsTableRecord ucs;
Matrix3d xform = Matrix3d.AlignCoordinateSystem(
Point3d.Origin,Vector3d.XAxis,Vector3d.YAxis,Vector3d.ZAxis,
ucs.Origin,ucs.XAxis,ucs.YAxis,ucs.XAxis.CrossProduct(ucs.YAxis)
);
