1 Choose Layers > New to create a layer.
2 Rename the layer body.
3 Choose Pick > Object . Click-drag a pick box over all the geometry to
select all the surfaces.
4 On the Layer Bar, click and hold on the body layer to see the pull-down
menu. Choose Assign to assign all the surfaces onto the layer.
5 Choose Pick > Nothing to deselect all the surfaces.
