6.Choose two machine parts (one component and one assembly) of reasonable complexity from any of the
drawing books.
a. Discuss the topological and geometrical aspects of the components in a coherent manner (point wise).
b. Discuss steps to create the component by B-rep method.
c. Discuss steps to create the components by CSG.
d. Use any of the available solid modelers to create the components.
7.Can half spaces be modeled using freeform patch definitions discussed in Chapter 7. Are such patches
unbounded? If not, can the intersection between freeform surface patches still constrain the material to lie
within a finite volume?
8.For the solid shown in Figure 8.19(d), draw the CSG tree.
9.Review the literature to learn about how solid modelers display various features.
