I tried as you said but i am not getting even bevels on all edges. Look at the model before i selected edges for beveling. How i clean up this model. Do you have any ideas for modeling it in any other way so that smoothing arc edges becomes easier for me. Basically i am trying to model Alienware Xmorph WMP skin. Any modeling ideas or sujjestions thax. I am really thanful that you are helping me.
