bolt and a hexagonal head bolt together with its nut (Fig. 14.5). With the
Create tool save each separately as a block, erase the original drawings
and save the fi le to a suitable fi le name - in this example Fig05.dwg.
2. Open the DesignCenter, click on the Chapter 14 directory, followed
by a click on Fig05.dwg . Then click again on Blocks in the content list
of Fig05.dwg . The fi ve 3D models of fastenings appear as icons in the
right-hand side of the DesignCenter (Fig. 14.6).
3. Such blocks of 3D models can be dragged and dropped into position in
any engineering drawing where the fastenings are to be included.

Constructing a 3D model ( Fig. 14.9 )

A three-view projection of a pressure head is shown in Fig. 14.7. To
construct a 3D model of the head:

1. Select Front from the View/Views panel.
2. Construct the outline to be formed into a solid of revolution (Fig. 14.8)
on a layer colour magenta and with the Revolve tool, produce the 3D
model of the outline.
