5. In the To p viewport, construct two cylinders central to the extrusion,
one of radius 50 and height 30, the second of radius 40 and height 30.
With the Subtract tool, subtract the smaller cylinder from the larger.
6. Click in the Front viewport and move the cylinders vertically by 5
units. With Union form a union between the cylinders and the web.
7. Still in the Front viewport and at one end of the union, construct two
cylinders, the fi rst of radius 10 and height 80 , the second of radius 15
and height 80 . Subtract the smaller from the larger.
8. With the Mirror tool, mirror the cylinders to the other end of the union.
9. Make the To p viewport current and with the Move tool, move the
cylinders to their correct position at the ends of the union. Form a
union between all parts on screen.
10. Make the Isometric viewport current. From the View/Visual Styles
panel select Conceptual .
Fig. 13.11 shows the result.
Fig. 13.11 Second example - Four: Left viewports
Third example - Three: Right viewports ( Fig. 13.13 )
1. Open the Three: Right viewport layout from the View/Viewports
popup list ( Fig. 13.3 ) .
2. Make a new layer of colour Green and make that layer current.
3. In the Front viewport (top left-hand), construct a pline outline to the
dimensions in Fig. 13.12 .
4. Call the Revolve tool from the Home/Modeling panel and revolve the
outline through 360 degree.
5. From the View/Visual Styles panel select Conceptual .
The result is shown in Fig. 13.13 .
