Lesson 43 | Using Blocks

This lesson describes how to create a block definition and insert a block definition or file into a drawing. For example, in the following illustration, the single block object on the left was created from all of the geometry on the right. The block object keeps all of the geometry tied together. The chair on the right is made of individual lines, arcs, and polylines while the objects on the left are a block definition; you can insert them into a drawing as a single object.

Using groups of objects to create block definitions that act as a single object can help you work more efficiently. Multiple objects that are defined as a block increase the reusability of that geometry when you or others use the block in other drawings ...
