The format of the following command is incorrect:

selection = Selection.Create(FaceSelection.SelectAll())

The FaceSelection() function already creates a selection type, so just do:

selection = FaceSelection.SelectAll()

Also, for later use, you'll want to get the DesignBody or DesignFace from the CircularSurface() function:

circlebody = circle.CreatedBodies[0]

circleface = circle.CreatedBodies[0].Faces[0]
