RhinoDoc vs DocObjects

Hi,

Could someone explain what is the difference between RhinoDoc and DocObjects? I understand by reading rhinocommon that RhinoDoc is a class under Rhino namespace, and DocObjects is another namespace(Rhino.DocObjects), but it sounds like to me they are basically dealing with same things. For example, i can do pretty much the same things with those two as below.

var obj1 = Rhino.RhinoDoc.ActiveDoc.Objects.FindId(id);
Rhino.DocObjects.ObjRef oRef = new Rhino.DocObjects.ObjRef(obj1);
Curve crv1 = oRef.Curve();

var obj2 = new Rhino.DocObjects.ObjRef(id);
Curve crv2 = obj2.Curve();

A = crv1;
B = crv2;

The only difference that i see between the two is the additional code in the 2nd line, I am speculating RhinoDoc only retrieve information of geometries on the active rhino file, and DocObjects brings in geometries in the active rhino file by referencing - I am not even sure if I am describing it properly - I am just an architect!

I wish i could find a good documentation or book to better understand the fundamentals in rhinocommon… Any comments, suggestions will be much appreciated. Thanks in advance.

Best,
W
