Introduction • Auto CAD is a CAD (Computer Aided Design or Computer Aided Drafting) software application for 2D and 3D designanddrafting. • Developed and sold by Autodesk, Inc. Initially released in late 1982. • It currently runs exclusively on Microsoft operating systems.
“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 corporatesindustry standards for design and animations.
AutoCAD FASHION INDUSTRY ENGINEERING ARCHITECTURE
Benefits of AutoCAD • User friendly software • Simple to use and saves time • Quickly create designs • Familiar to designers and engineers • Accessible and accurate with information
More Accurate than Hand Drawings • Improved quality over hand drafting • Can be customized to suit the individual’s needs • Teaches a marketable skills
Coordinate System X, Y coordinate system
Features of Productivity Tools Block of a Window
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 2-D A concept of displaying real-world 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. A basic solid building block. Examples would be boxes, cones, cylinders. Primitive Region 2-D area consisting of lines, arcs, etc.
Rendering A complex way of adding photo-realistic 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. Solid Model UCS 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.
Creating Solids Slice Thickening Revolve
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.
