This chapter began by introducing us to assemblies and multibody parts. We then applied these concepts in order to redesign our roof truss model that we've used through the previous two chapters into an assembly. Next, we added the roof truss to MakerWare and went through the necessary steps selecting the colors for each component and specifying build settings. We ended by showing multiple ways by which we could print multicolored parts that depend on our MakerBot. In the next chapter we will be going into more detailed assemblies and will introduce the concept of tolerancing in order to create larger, more complex assemblies.
