Organize Drawing Information
In both manual drafting and CAD, you need a way to organize your drawing content—a method for
separating, sorting, and editing specific drawing data.
With manual drafting, you can separate
information onto individual transparent
overlays. For example, a building plan might
contain separate overlays for its structural,
electrical, and plumbing components.
With AutoCAD and AutoCAD LT, layers are
equivalent to transparent overlays. As with
overlays, you can display, edit, and print layers
separately or in combination.
You can name layers to help track content, and lock layers so
they can't be altered. Assigning settings such as
color , linetype , or
lineweight to layers helps you comply with industry standards.
You can also use layers to organize drawing objects for plotting.
Assigning a
plot style to a layer makes all the objects drawn on
that layer plot in a similar manner.
This drawing of a press uses layers to define different linetypes
and colors.
Turn off layers to hide complex
details as you work.
Display layers when you need
to see all components.
