Introduction
Auto CAD is a CAD (Computer Aided
Design or Computer Aided Drafting)
software application for 2D and 3D
designand drafting.
Developed and sold by Autodesk, Inc.
Initially released in late 1982.
It currently runs exclusively on
Microsoft operating systems.
Why it is so Popular in
Architectural &
Construction Industry?
“AutoCAD is one of the most
popular Computer Aided Design
programs developed to help
professionals design and analyze
buildings or structures without
having to draw up plans
manually.
While CAD applications prior to
AutoCAD involved large amount of
computing power in the form of
gigantic computers.
 AutoCAD has simplified its
operations to optimize it for the
IBM PC, allowing people to work
from home or on their own
workstations.
AutoCAD uses DWG as a
standard file format which is now
largely accepted as a standard for
all CAD design and drafting
work.
 As per industry estimates there
are more than 1 billion DWG files
are in operation around the
world today
AutoCAD has many in-built tools
to help architects or designers
work on individual projects.
 The software is comprehensive in
its nature focusing more on
2D/3D renderings and also in
corporates industry standards
for design and animations.

Block and External reference
Block and External reference means
sharing and reusing the resource of
drawings.
You can easily to insert another drawing
in current drawing.
you can not only define your block and
attribute block, but also you can edit
them easily with In-place
Edit function, by double-click, you can
edit the relevant block.

Design Center
Design Center offers you a convenient way
to manage the issues of your drawing
such as dimension style, blocks, text style,
line types and layers.
Just drag and drop, you can apply them
from any source drawing to your current
drawing.

Plot & Plot style
Once you have completed a drawing, you can
use a number of methods to output the
drawing.
You can plot the drawing on paper or create a
file for use with another application.
In either case, you select the plot settings.

INTRODUCTION
- WHY
3-D?
You may have already figured
out why CAD has many advantages
over manual drafting.
One big advantage is that once
you've drawn something, you
shouldn't have to draw it again.
If you manually drew a house plan,
you would have to draw a front
elevation, side elevations, and
possibly a perspective view.
With 3-D CAD model, you can
generate views from any angle
either inside or outside the house
and animations.
Afterwards, if your client needs
something changed, you can then
make the changes once
You'll be learning the 3-D concepts
in the following order:
Isometric Drawings (not true 3D)
Wire-frame (very basic 3D)
Surfaces / Regions (primitive 3D)
Solid Objects (advanced 3D)
3-D CAD TERMINOLOGY
A concept of displaying real-world
2-D
objects on a flat surface showing only
height and width. This system uses only
the X and Y axes.
3-D
A way of displaying real-world object in a
more natural way by adding depth to the
height and width. This system uses the X
Y and Z axes
Boolean operations
Commands that allow you to add,
subtract or intersect solid objects in
AutoCAD.
Isometric
Drawing
A simple way of achieving a
'3-D' appearance using 2-D
drawing methods.
Primitive
A basic solid building block.
Examples would be boxes,
cones, cylinders.
Region
2-D area consisting of
lines, arcs, etc.
Rendering
Solid Model
UCS
A complex way of adding photorealistic qualities to a 3-D model
you have created.
3-D model creating using solid
'building blocks'. This is the most
accurate way of representing
real-world objects in CAD.
The user co-ordinate system. This
is defined by the person drawing
to have easier access to portions
of a 3-D model.
Wire-frame Model
A 3-D shape that is defined by lines and curves.
A skeletal representation. Hidden line removal
is not possible with this model.
Viewport
A window into your drawing showing a
particular view. You can have several viewports
on your screen. Different from the viewports
used in plotting.
Extrude
The extrude command raises the shape of
a 2D outline into a 3D solid. For example,
a circle would be extruded into a cylinder.
Press Pull
Press pull command is used to raise shapes of 2D
outline into 3 D in much simpler way or with
single command.
3D Objects: Primitives
Box
Pyramid
Cone
Cylinder
Sphere
Creating Solids
Extrude: It is the method to convert 2D
figure into 3D giving it a specific hieght.
Sweep : Using this u can make any
type of three 3D object on a given path.
Loft

Walkthrough
You can now fly or walk through
your model using navigation similar
to a first person video game. You can
record, save, and play a scene. You
can move the camera in such
directions which you want to
visualize.
Rendering
In Rendering
we can create a
photorealistic or realistically shaded image
of a three dimensional wire frame or solid
model.
It shades the scene's geometry using the
lighting you've set up, the materials you've
applied,
and environmental settings such as
background
and
fog.

The Product :- 3D Studio Max
3ds Max is a 3D modeling, animation and
rendering program from the Media and
Entertainment division of Autodesk, Inc., Widely
used in the areas of Architecture, interactive
games, visual effects for movies and industrial
design models. It has strong modeling capabilities,
a flexible plug in architecture and a long heritage
on the Microsoft Windows platform.It is also used
for movie effects and movie pre-visualization.

Cameras
•
•
Virtual cameras duplicate the functions and
controls of real-world cameras.
What controls does a real-world camera
have?
A. Focal length
B. Field of View
Camera View
Reflections & Radiosity
• Ray-tracing algorithm takes into account
reflections and radiosity
Translucency and Refraction
• A translucent
material transmits
light, but unlike a
transparent material,
it also scatters the
light so those objects
behind the material
cannot be seen
clearly
• Simulate frosted and
etched glass
Environments
• You can use an image as a background
