You can create a copy of most nongraphical and graphical objects in a database. You create a copy of an object with the Clone function. Once an object is cloned, you can modify the returned object before it is added to the database. You can mimic many of the modifying commands in AutoCAD through the use of the Clone and TransformBy methods.
Along with creating a direct copy of an object, you can also use the Clone and TransformBy methods to offset, mirror, and array objects.
