In this chapter, we have learned about XRefs, which are a great collaboration tool that's built into AutoCAD, and we also explored the dynamic block tool. We used the concepts of parametric drawing to make our dynamic block, and we also made dynamic blocks using parameters and actions, which are the core features of the dynamic block tool. Finally, we learned how to fix broken drawings and clean bloated ones using tools such as AUDIT and PURGE.

From the next chapter, we will start covering AutoCAD's 3D tools, and we will begin by looking at the 3D user interface and the common tools required to understand the workings of the 3D workspace of AutoCAD. Then, we will gradually move to the drawing and modification tools of AutoCAD 3D.
