Good morning. I am doing the Car Modeling Tutorial of the BMW. I am attempting to separate the hood from the body. When I select the faces of the hood and use the command separate I get the error saying "Error: polyToSubd2 has only one piece. Ignored". I am wondering if there is a way correct this and to separate the hood from the body when I am getting this error message.

And it is a poly object. It says in the Channel window subTessShape1 when it is selected. I do not believe I have Tessellated the model, as it does not appear to be.

Thanks!!
