This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.
The basic idea of this assignment is to suggest software to a Client who is a small tooling manufacturer. The business of the Client is originally to design, analyze and manufacture parts and tools for molding purpose of plastic containers, for example bottles, storage boxes, etc. The client uses AUTOCAD and MASTERCAM in order to design and manufacture the parts and tools but most of the customers of the client use SOLIDWORKS, AUTOCAD, INTERGRAPH NX and 3D STUDIO MAX. So the client has to interpret or translator before the use of the design of the customer. The main objectives of the client are preparing CAD models for the tools and parts, creating both engineering and production drawings, analysis of mechanical and injection molding and also developing CNC part programs for the tools and parts to be manufactured. But due to difference of software used by the client and the customers there exists an importance of communication with the customer before the designs are finalized to be manufactured. The customers have some requirements like the client should be working under the ISO9000/I and the files and data that are received and created should be controlled and managed.
CAD stands forÂ computer-aided design. It is also known as CADD, which stands forÂ Computer-Aided Design & Drafting. This software is used in creating plans and to construct drawings by architects, engineers, drafters and artists. The software is very efficient as the software has the capability to record lines on vectors based on mathematical equations. It also has features such as the drawings can be twisted and moved and the picture is automatically adjusted.
CAM stands for Computer Aided Manufacturing. The system sets the tool path and executes accurate machine operations based on the design of the part or tool to be manufactured. CAD and CAM are connected toÂ each other directly. The integrated CAD/CAMÂ system is then takes the design generated by the computer and is then fed into the manufacturing system and then the design is changed into multiple computer-controlled processes, such as drilling or turning.
Functions of CAD/CAM:
The basic function of CAD is to create two-dimensional (2D) and three-dimensional (3D) views, to zoom in and out for close-up and for distant views, to rotate images in order to outlook the images in different perspectives and to change the scale of images. When one of the values is changed the related values are automatically adjusted. It also manipulates the shape of the images as changing one part of an image automatically changes the whole.
CAM enables the automated integration of the manufacturing process with other mechanization systems like Computer-Integrated Manufacturing (CIM), Integrated Computer-Aided Manufacturing (ICAM), Flexible Manufacturing System (FMS), Direct Numerical Control (DNC), and Manufacturing Process Management (MPM).

Some of the CAD/CAM software are
3D Studio Max
Auto Cad is as defined as Computer Aided Design software product that is used for the two or three-dimensional drafting and designs. It was developed by auto desk and was introduced in the year 1980 , and released on December 1982 .At that time this is used to promote the feature extensibility and customization. And it was too expensive and there were limited features also. But now a days, it includes the three-dimensional tools and full set of basic solid modelling. It can be easily used as a platform for others like Bentley Auto Plant and Coade Cadworx. But of course it is vector graphics drawing program and the primitive entities that are used are the circles, arcs, lines, etc. Now it was running on the Microsoft desktop operating systems and is available in many languages
HOW TO CREATE 3D DRAWING IN AUTOCAD:
Even though AutoCAD has a number of commands for creating special 3D objects, lot of change can be achieved by changing the properties of basic 2D objects like polylines. Most 2D objects can get more thickness by using this command(DDCHPROP) command. we can extruded the thickness objects, with the EXTRUDE command which creates solid extrusions. By obtaining an object thickness it produces a surface extrusion. All objects can be given an elevation by moving them in the Z direction using the MOVE command. With a combination of the MOVE and Properties commands you can quickly create simple 3D drawings

It is used for 2D and 3D high speed machining for complex parts
It is software used for designing and manufacturing parts and tools. At present this software has a great demand in the market. Now every company and competators are using this software. By using this software 3D designs and models of various products can be created that would work efficiently and its performance will be long-lasting .it is very easy to make transition by observation it is known that moving from 2D to 3D involves more than just buying new software it also requires to think differently about how you approach the design process. SolidWorks can help all users become more productive. Than using complex rules, design team can focus on creating better products, not software.
Solid Works, will works with a locally-based Value-Added Reseller. The Reseller will help to formulate an implementation strategy, provide comprehensive training, and deliver full technical support.
Test it before you build it: SolidWorks SimulationXpress is a design validation tool that's included with every copy of solid works 3D CAD. It helps to test the designs earlier in the design cycle, on-screen and against real-world conditions. It leads to improve the design quality and manufacturing efficiency, while reducing time to market, costs, and materials waste. In a different MIT survey, 66% of respondents reported improved design quality resulting from Solid Works design validation tools.
Collaborate, communicate, and share data: solid works plays well with others it can share models and work with one another, suppliers, and manufacturers to refine designs, maximize accuracy, and it improve production efficiency.
Work in a single application: No one likes having to open multiple applications to finished a single task. It's slows down the computer.. Luckily, solid works users can work from product concept to accurate virtual prototype without ever opening another application.
At SolidWorks, weÂ know that great ideas can come from anywhere. In fact, a growing number of SolidWorks Partners are creating applications that seamlessly integrate specialized capabilitiesÂ with the SolidWorks platform. That means if there's a special capability like to have

HOW SOLID WORKS CREATE PARTS:
Power CAM is a direct Mazatrol or G-code output form within the Solid Works interface. This product allows Solid Works users to create parts and output CNC code, often within a few minutes. The program joints the power of a Mazatrol off-line programming system (a CAD/CAM system) and engineering software into one system. The MazaCAM Editor is an off-line Mazatrol programming system.
GeoPath is a system that can output G code; it integrates with the MazaCAM to output the Mazatrol. Power CAM connect with Solid Works, MazaCAM and GeoPath into a programming system, taking advantage of the feature information present in the Solid Works model.
we will use this software can take a native SolidWorks file, assign tooling and output Mazatrol directly. We can also view tool motion; calculate run times; generate tool sheets; output codes for virtually any CNC.
OVERVIEW OF SOLID WORKS:
First of all Solid works will work by creating part in 3D or solid form. They are three components which are mainly uses in solid works that is Part, Assembly and Drawing. Part define by it sketch and selected feature. Assembly is how all parts must be assemble in one unit, parts assemble by user adding mate between parts. Drawing is for detailing and adding dimensions to part. solid works main idea is user must create drawing directly in 3d or solid form .from this solid form user can assemble it directly on there work station by checking clashes and functionality of it. Creating drawing in an easy way and drop the solid to drawing block
Part is created by sketch
Sketch is the base to define the part, form and features
Before start creating sketches we must select plane or face where the sketch will be sketch on it and add features.
This is nothing but how all parts work together in assembly. There after we have to check it out for clashes and its functionality. first of all parts are inserted in assembly by insert component tool .After inserting all parts in a workspace and there after we have to check it out for functionality .Mate is a command how parts mate with each other .After assembling all parts its represents like that
This is use for detailing part by adding dimension to it. The pictorial represents for drawing is
DIFFERENCE BETWEEN SOLID WORKS AND AUTOCAD:
Solid works is a "parametric" solid modeller used for 3D design.
AutoCAD is primarily a 2D design tool that does have some 3D capability,
It is easy to compare any parametric solid modeller even though 3D is improved in AutoCAD 2007.
Autodesk (creator of AUTO CAD) makes a product that is almost identical to solid works called Inventor, which is a parametric program for design of solid parts and assemblies.
It is very to know that Parametric simply means the dimensions can have relationships between one another and can be changed at any point during the design process to mechanically change the solid part and any related documentation
3D STUDIO MAX:
This software is based on a plug-in architecture. Any one can extend its functionalities by developing scripts and plug in using the SDK and the Maxscript language..This software has two goals they are
Create images or movies using 3D content (short movies, special FX, architecture)
Create 3D content to be used by another software
Plug-ins expansion can be done in both fields because both are common process.
The main functionalities of 3D Studio Max programming using the SDK in C++ language. Max SDK is something difficult learn but after learning know this software we can easily expand it
3D studio max is accomplished only by using Microsoft Visual
Studio 6 (for versions prior to 5.1) or Visual Studio .NET 2002 for versions of 3D Studio Max and It is not recommended to use another compiler
Different type of plug ins CATOGORIES
It is a general class of developer-defined things that can be used in 3ds max.
These are the only procedural objects that actually get rendered.
Primitive objects such as boxes, spheres, cones, cylinders, and tubes are implemented
as procedural geometric objects.
Compound objects take several objects and combine them together to produce a new
Developers can develop patch modelling systems that work inside MAX.
The NURBS provides an interface into the NURBS objects used by MAX.
Helper objects are items such as dummy objects, grids, tape measurers and point
These are shapes such as Circles, Arcs, Rectangles, Donuts, etc.
These are shapes that are defined procedurally.
Developers may create custom plug-in lights.
They may create custom cameras. The two classes from which cameras may be
derived are Camera Object and GenCamera.
Object modifiers are applied to objects in their own local transform space to modify them
This plug-ins allows specific object types to be edited. For example, an Edit Mesh modifier
Space Warps are basically object modifiers that affect objects in world space instead of in the
Object's local space
REQUIRMENTS OF 3D STUDIO MAX:
It is also known as 3ds Max, is a graphic design application by Autodesk. It has been used in the development of so many games and movies in the 21st century and is careful to be an industry model for 3D-computer-aided design.
This software is not for an common user. This software mainly uses for large scale industry because its too expensive. These are some requirements which are used for 32 version
. 3D Studio Max requires at least an Intel Pentium 4, AMD Athlon 64 or AMD Operton microprocessor.
To run 3D Studio Max, we must have at least 1GB of RAM, although 2GB is recommended..
A fully working , three-button mouse is required .
3D Studio Max has to offer, as is DirectX 9.0c.
A 128MB graphics card with Direct3D 9, Direct3D 10 or OpenGL support is also required.
Finally, the entire program takes up 2GB of space on computer's hard drive.
