Layers in AutoCAD allow users to organize a drawing into separate sets that can each be manipulated independently. Layers control properties like color, line type, visibility, and more for individual parts of a complex drawing. Common layer commands include creating new layers, turning layers off to simplify the drawing view, freezing layers to improve performance, and locking layers to prevent accidental changes.

3. Engineering Drawing
A graphical language used by engineers
and other technical persons associated
with engineering profession.

4. AutoCAD
AutoCAD is a computer-aided design
(CAD) program used for 2-D and 3-D
Design and drafting.

5. Layer
 It is an AutoCAD command which is
used
when we are dealing with complex
geometries like building structures,
wiring
system etc.
 It allows you to control the colour, line
type, activity and visibility of individual
part of the drawing.

click on the new button in the layer
window.

Turn off layer
You turn off layers to reduce the visual
complexity of your drawing while you work.

11. Freeze layer
You freeze layers that you do not need
to access for a while. Freezing layers is
similar to turning them off, but improves
performance in very large drawings.

12. Lock layer
You lock layers when you want to
prevent accidental changes to the
objects on those layers. Also, the
objects on locked layers appear faded,
which helps reduce the visual
complexity of your drawing, but still lets
you see the objects faintly.
