The previous chapter contained information about how to perform the basic editing tasks by clicking objects. In addition to those editing features, you can use editing tools and commands that are unique to CAD drawing.
This chapter provides information about the editing tools in the 2D Draw control panel and in the Modify menu. These tools do everything including joining line endpoints, extending objects to meet other objects, and breaking objects in two. In this chapter, you'll also learn how to edit blocks and external references (xrefs), which are collections of objects that act like a single object. And since polylines are fairly complex, they have their own editing tools, which you'll learn about toward the end of this chapter.
