Select the top case half.
Move the mouse over the 3D Design-Turntable switch
lower right and down the smart selection ladder one level from the active level,
then double-click.
Dynamic highlighting shows you the active level. Parts not in this
level are transparent.
Start to drag the bottom face of the top half of the plastic case toward the
bottom half, then release the left mouse button.
The top half of the case is attached to the pointer.
Move the mouse pointer over the top face of the bottom half and click.
The two parts snap together. Notice, however, that the fit is not
perfect.
