back on and move the top into its correct position relative
to the main part of the valve. Then with the
Mirror
tool, mirror the
top to produce the bottom of the assembly (Fig. 17.8).

In the
UCS X
view, construct one of the bolts as shown in Fig. 17.10,
forming a solid of revolution from a pline. Then construct a head to
the bolt and with
Union
add it to the screw.

With the
Copy
tool, copy the bolt 7 times to give 8 bolts. With

Add suitable lighting and attach materials to all parts of the assembly
and render the model.
