1. how to get unnamed ucs ucstablerecord ?
2.which property of ucstablerecord is ucs transform matrix?

[#2]

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)

);

If i use ucs command in autocad , and select parameter "object: to set new ucs, autocad will generate a unnamed ucs.

Ok. I see what you mean. This simply sets the "current" ucs. It doesn't
create a new anonymous UcsTableRecord. I guess we just had a different
understanding of what "unnamed ucs" means.
