Abstract - The CAD/CAM software available in the market
are general purpose software. These software are not
developed for particular user or a particular task. Theprocess
of modelling of the software for particular application to suit
the specific requirement of the customer is called as
customization of software. Various industries use UG/NX to
perform the task of solid modelling, assembly modelling and
drafting of the various engineering products. Due to the wide
variety of applications, couplings of various types are used
frequently by many industries. The aim of this work is to
customize UG/NX CAD/CAM software, toprovidefacilitiesthat
generate three dimensional part model of Flange’s coupling,
and its assembly model using knowledgefusionprogramming.

1. INTRODUCTION
The concept of mass customization has become increasingly
popular since the 1990’s (Pine, 1993). This is due to
customization offerings a competitive advantage to
companies with increased customer value. Furthermore, in
keeping with the evolving paradigm of mass customization,
Meyer and Utter back (1992) also introduced the concept of
product family design, where standardized products can be
replaced with specificfeaturesandfunctionalityaccordingto
customers’ specific needs and desires. One may conclude by
these studies that by automating the design process toallow
the customer more range of direct, interactive control with
the design, companies could experience a significant
reduction in operation costs. Withtoday’semergingmarkets
and product variety, it is very important for industrial
companies to explore product customization to capture
customer attention and deliver true customer value. The
challenges are formidable, especiallywithtoday’scustomers
who consistently demand “a product with the highest
quality, fastest delivery, and highest level of product
customization” (Kumar, 2008). Unfortunately, most of
today’s product customization falls under the category of
customized standardization (Lampel & Mintzberg, 1996),
where the customers are not involved in the design and
manufacturing process, as depicted in Figure 1 below.
Computer-aided design (CAD) software available in market
are tremendously improving the productivity of designer by
facilitating various features that reduce the product
development time. However, it is observed that most of the
manufacturingindustriesfrequentlydesignandmanufacture
similar type of components only or the assembly often
consist of use of standard parts. The designer has to model
the similar products repeatedly in both cases. This is not
only time consuming but also it creates fatigue in the
designer’s work. If designer is provided with custom
programs for parts and assembly, he has toonlyinputvalues
for key parameters in the dialogue box and the part will
automatically get generated.
1.1 Objective
 Consistent designs
 Ease of use, allowing low skilled manpower to
handle design load
 Increases the productivity
 Minimize errors
 Link CAD to other applications, such as MS-Visual
Studio using the latest technologies
 Faster designs
 Accurate designs sticking to standards
 Automation of CAD is done essentially to
minimize the time consumption and maximize the
productivity; this is done ARX, Lisp and VBA with
enhancement in Auto CAD instruction and
producing well-informed drawings.
1.2 Future Scope
 CAD Automation is mainly used for Facility
management, Hotel Industries, Symbol or block
management, File Data management and so on.
 Digitize design outputs in the form of 2d drawings,
3d models, prototypes
 Avoid repetitive tasks in design
1.3 Methodology
The purpose of this project was to create a tool to allow
customers to be more involved in the design phase for
product customization through the use of aninterfacethat is
seamlessly integrated with CAD’s system API. Figure 4
displays the system architecture for this project.

Fig.1.5 The system architecture
Basic activities and information flow of the system
architecture are summarized by the following description:
 A user-interface form was developed for the
customers using Visual Basic language.
 Customers input values for pre-identified feature
dimensions for a product mode.
 A new product model will then be design according
to the customer’s parameter values via CAD’s
system application programming interface (API).
In short, this technique provides customers with the ability
to make design changes to the product without the need to
possess design skills in CAD software. In essence, this
method attempted to close the gap of misinterpretation in
product customization betweenthedesignengineersand the
customers. Most importantly, this project educates the
customer about what options are available for them.
2. CUSTOMIZATION LEVELS
The major CAD systems have a wide range of customization
interfaces that go from as simple as assigning commands to
function keys to complete development environments
including high level programming languages and resource
compilers. CAD systems usually offer the following choices:
• Function keys assignment: This is a fairly simple way to
issue a written command. Thekeys,frequentlynamedF1,F2,
etc., are assigned a command that is “typed” whenever the
corresponding key is pressed.
• Configurable menus: New items are added to the standard
menu tree of the program. The new item, represented by a
word or icon, is assigned a command to be executed when it
is selected. Sometimes, creating menu items can be a fairly
complex task.
• Scripts: These are simple sequences of instructions stored
on disk files that are run through a specific command of the
CAD system. By assigning scripts to function keys or menu
items is possible to speed up many tasks.
• Symbols library: Different CAD systems call them blocks,
parts or cells. A symbol is a small drawing of a frequently
used part. Symbols are assigned names and are placedin the
design with arbitrary rotations and/or scale factors.
• Interpretedprogramminglanguages:Theseareproprietary
programming languages whose interpreter is built into the
CAD program. AutoLisp (for AutoCAD), UCM (for Micro
Station) and CADL (for CADKEY) are a few examples. Some
of them, like AutoLisp, resemble high level programming
languages.
• Compiled programming languages: Similar to interpreted
languages but the source code needs to be compile before it
can be used. Compiled customizations run faster and are
better suited for large applicationsthatcaneasilyhavemany
thousands of source code lines. ADS (forAutoCAD),MDL(for
Micro Station) and DCAL (for Data CAD) are some examples.

3. PROGRAMING
Visual Studio is the one of the best tool for programing.
Following steps are followed for designing the flange
coupling
Step 1 – Integrating Visual Studio with NX 10
Step 2- Creating Form for input parameter
Step 3- Gives Input parameters (Power to be transmitted,
Rotational Speed (RPM))
Step 4 - .esc format to .dll format generation
Step 5 – Displayed final assembly on screen
4. CONCLUSIONS
We program for the application for various input
parameters and designing conditions and came across
the following conclusion, how the customization
approach is beneficial to the designing department of
the company,
As the saved for the operation the product lifecycle
time reduced.
Drawing generation tasks from parametric models
become efficient.
Designing cost to the company is reduced.
Reduction in error generation.
