In this chapter, we learned about adding details to our drawings using properties such as linetype, lineweight, color, and transparency. We also learned how to apply these properties on a drawing level and on a layer level. We also learned about classifying drawing objects into layers and controlling their collective properties using layer tools. The tools related to managing lists of layers and layer states, and quick access tools on the Layers panel were also discussed. 

In the next chapter, we will learn how to make symbols, often called blocks, in a drawing, and we will also learn how to use this reusable content. We will also learn how to add dimensions, text, and other annotations to our drawings, which will ultimately make our drawings more readable.
