How to save selected file in assembly with new name and checked as a copy?

Now i try this:



if (saveFile.ShowDialog() == DialogResult.OK)
                        {
                            string path = "";
                            path = saveFile.FileName;
                            swModExt = swModel.Extension;
                            swSelMgr = (SelectionMgr)swModel.SelectionManager;
                            swCompEnt = (Entity)swSelMgr.GetSelectedObject6(1, -1);
                            swComponent = (Component2)swCompEnt.GetComponent();
                            IModelDoc2 newPart = (IModelDoc2)swComponent.GetModelDoc2();
                            boolStatus = newPart.SaveAs(path);
                        }
