This chapter was mostly about customizations. We learned how to customize the user interface of AutoCAD and how to create custom objects. The customization tools that we discussed help personalize the user interface and make us more efficient in our drawing workflow. The custom linetype and Hatches are other great features available in AutoCAD, and they are especially useful when you need a project-specific linetype or Hatches pattern. Design Center, tool palettes, and external sources of blocks reduce our dependency on making blocks every time we need them and make the process of making drawing much easier and faster. Finally, we discussed the polyline and spline tools in detail.

In the next chapter, we will discuss external references and dynamic blocks, and both of them are interesting topics. We have already seen dynamic blocks in action in the tool palette section, and in the next chapter we will learn how to make our very own dynamic block. So, I will see you in the next chapter.
