Lesson: Using Layers
This lesson describes what layers are and how you can use them to organize objects in your drawing.
For example, in the following illustration, objects might be placed on different layers, with dimensions
on one layer, hidden lines on another, and the hole features isolated on a third. Each layer may have
property settings that determine the color, linetype, and lineweight of the objects on that layer.
In a typical drawing, objects are placed to represent some part of the design. These objects can include
geometry, text, dimensions, and borders. To organize your drawing, you need a way to logically group
objects based on function, appearance, or other commonalities. There are many industry layering
standards and most designers base their own standards on one of these. Most important is that you
establish a standard for layering and you follow it.
After completing this lesson, you will be able to use layers to organize objects in your drawing.
