Comprehensive Report on CAD Systems and IS Development Methodologies

This report provides a detailed overview of Computer-Aided Design (CAD) systems and the Information System (IS) development process. It begins by exploring various types of CAD systems, including 2D, 2.5D, and 3D CAD, discussing their functionalities, applications, and software examples like AutoCAD, Revit, Inventor, SolidEdge, SolidWorks, and VX CAD. The report then delves into the IS development process, outlining the Software Development Life Cycle (SDLC) methodology, which includes planning, analysis, design, development and implementation, testing, and maintenance phases. The SDLC methodology is explained, emphasizing its structured approach to managing large applications and mitigating risks. The report references key publications related to CAD and IS development, offering insights into the evolution and application of these technologies in engineering and software development.

Different types of CAD systems
Computer Aided design system was made for simplifying the advance engineering
drawing. This software is used for construction architecture and drawing in the various
engineering field (Ibrahim, Johar and Rahman, 2018). Various types of CAD system are
discussed below.
2 Dimensional CAD:
Two dimensional CAD is one of the most important software in the CAD system. It
was invented in the 70s. Big aerospace, automobile companies use this software at that time.
2D CAD uses basic shapes like lines, circle, and rectangles to create the drawing. Autodesk is
one of the most popular 2D CAD software available in the market. Autodesk tool is made for
design flagship products (Mabogunje, 2015). This software offers over eighty products.
Every product target different industries. AutoCAD is the flagship product of Autodesk. This
is the first product of Autodesk, and this is the most popular product of Autodesk. AutoCAD
can create product design, conceptual concepts and simulations by using 2D and 3D drawing.
At first, this software was created for mechanical engineers latter every industry use this
software. Another product is Revit. Revit is built for design building model. A designer can
create a 2D model as well as a 3D model in these applications. This software has a unique
feature like 4D BIM. By using this technology, designers can create a plan or track the
different stages in building life cycle. Inventor is another product from Autodesk. This
application is design for mechanical engineers. By using this software, the user can create a
professional mechanical design.
2.5 D CAD:
2.5D cad is developed between 2D and 3D cad. Bu using this CAD, prismatic model
can be created. The prismatic model provides the depth of any objects. 2.5D CAD uses

geometric objects to create the model. This CAD system allows a designer to import, create
or modify the models. This CAD is a representation of the 2D model.
3 Dimensional CAD:
3D CAD is the advanced version of 2D CAD. When computers increase graphics
capabilities, 3D CAD becomes one of the most popular tools. 3D cad allows designers to
create 3D images that are more realistic than 2D CAD. These 3D images are the 3D model,
and it can be viewed from any direction. This CAD was invented in the 1980s (Popa, and
Popa, 2017). These programs come with many varieties of products. Popular 3d CAD
programs are SolidEdge, SolidWorks and VX CAD. Solid edge uses technologies like
synchronous that can help a designer to create or accelerate the design of a product. By using
this software, a designer can improve their design and reuse the design. In the real world
environment, this tool allows designers to create digital prototypes (Onstott, 2016). Another
popular 3D CAD application is SolidWorks. By using this application, designers can create
an accurate 2D drawing very fast, and it can be updated automatically when the designer
change their 3D model. This tool provides a feature like a sheet metal, surfacing die design
and weldments. VX CAD is well known CAD application in the market. This application has
a unique ability like it can import other 3D CAD model and modify it (Mühlemann et al.,
2019). VX CAD is a hybrid cad application. This tool is the flagship product of VX corp.
Single file mode systems:
Only a single user can work on a single file in this type of CAD application.
Referenced file mode system:
In this CAD system, user can work only on their file. They can attach their file in
system background and modify it.

Collaborative model system:
In this CAD system, multiple users can work together, and they can see each other’s
changes. This type model provides how people can communicate and get the coordinates to
activities done.
3D Wireframe and Surface Modeling:
In this type of CAD software, a 3D wireframe can create the skeleton structure of a
model and surface can be added later. This type of software is very hard to use and rarely
used.
Solid Modeling:
This model is very useful because when a designer is creating an object, this program
can calculate the dimension of it. This type of CAD system uses the same logic as 2D CAD.
This tool is regular geometric shapes to create an object. Once an object created, it cannot be
modified in this type of system.
IS Development Process:
Information system development has a few steps that every big organization follows.
These steps are known as the software development life cycle (SDLC) (Paz, and Pow-Sang,
2016). These steps are discussed below.
Planning: In software development, life cycle project planning is the most important
step. Without a proper plan, measurement of weakness and strength of a system is useless.
Analysis: Developer must analysis the software in this step. Software Analysis is one
of the most important parts of any projects.

5OPERATIONS MANAGEMENT
Design: When the analysis is completed, developers start working on software
designing.
Development and implementation: The works on software development starts from
this step. In this step, developers record every record in the background. Once software
developed developer starts the implementation process.
Testing: In this step, developers check the software for any errors or bugs.
Maintenance: After completing all the process, the application will be in the
maintained phase where the developer upgrades the software from time to time.
SDLC Methodology:
System development life cycle (SDLC) methodology is one of the most important
methodologies in the information system. In 1960 this methodology was developed for
managing large applications (Wang et al., 2015). This methodology is very structured. By
using this method, various risks can be avoided. SDLC methodology is very similar to a
waterfall methodology. After completing one step, another step starts in this methodology
(Rahbari, 2018). After completing each step, organization can decide to move in the next step
or not. Developing software by using this methodology can take years to be completed.
SDLC provides quality software with the shortest time and lowest cost. SDCL provides
details plan for maintaining, develop or replace the system.
