1. Fig. 14.35 shows a Realistic shaded view of

the 3D model for this exercise. Fig. 14.36 is a
three-view projection of the model. Working
to the details given in Fig. 14.36, construct the
3D model.

Place the front half in an isometric view
using the ViewCube and shade the resulting
model.

3. Working to the dimensions given in the two

orthographic projections ( Fig. 14.38 ) , and
working on two layers of dif erent colours,
construct an assembled 3D model of the one
part inside the other.
With the Slice tool, slice the resulting
3D model into two equal parts, place in an
isometric view. Shade the resulting model in
Realistic mode as shown in Fig. 14.39.

2. Construct a 3D model drawing of the separating

link shown in the two-view projection (Fig.
14.37 ). With the Slice tool, slice the model into
two parts and remove the rear part.
