Help with objects in blender.

Hey everyone! I am a newbie blender user. I have been doing some modelling for over a month. I am working on this small project right now and there is this thing that is slightly bothering me. Well I created these two mesh objects in Blender in Edit mode. I have to apply subsurf modifier to only one of them, but since I accidently created both the meshes in edit mode Blender treats them as a single object, so whenever I apply the modifier, it is applied to both the ‘supposed-to-be-different-objects’. I face this thing quite often an I usually forget to switch to object mode before creating a new object. Now my question, is there some way that I could select a part from an existing object and transform that part into another different object? If yes, how? Any help would be appreciated. :slight_smile:

Select the mesh you want to separate into a new object and press P.
