“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 uses DWG as a standard file format which is now largely accepted as a standard for all CAD design and drafting work.
AutoCAD has many in-built tools to help architects or designers work on individual projects.
X, Y coordinate system
Block of a Window
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.
- WHY 3-D?
If you manually drew a house plan, you would have to draw a front elevation, side elevations, and possibly a perspective view.
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.
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
Commands that allow you to add, subtract or intersect solid objects in AutoCAD.
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.
2-D area consisting of lines, arcs, etc.
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.
The user co-ordinate system. This is defined by the person drawing to have easier access to portions of a 3-D model.
A 3-D shape that is defined by lines and curves. A skeletal representation. Hidden line removal is not possible with this model.
A window into your drawing showing a particular view. You can have several viewports on your screen. Different from the viewports used in plotting.
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 command is used to raise shapes of 2D outline into 3 D in much simpler way or with single command.
Extrude: It is the method to convert 2D figure into 3D giving it a specific hieght.
Slice Thickening Revolve
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.
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.
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.
What is the difference?
Why use them?
“Separate scene objects into easy-to-select and easy-to-work-with groupings”
