Layers are a powerful way to organize information in drawings. You place similar kinds of entities on their own layers, such as all doors on a DOOR layer or stairs on a STAIRS layer. This lets you to two actions: change their properties as a group (such as color or linetype), and turn unneeded layers on and off. In this video, you learn how to use the Layer command to change properties of entities, move entities to different layers, change the status of layer, such as freeze them or prevent them from printing. You also learn how to move entities from one layer to another.
