<h4>Introduction</h4>
<p style="justify-content: center"><strong> CAD (Computer Aided Design) is the use of computer software to design and document a product’s design process. Engineering drawing entails the use of graphical symbols such as points, lines, curves, planes and shapes. Essentially, it gives detailed description about any component in a graphical form. </p>
<p>• CAD is used to accomplish preliminary design and layouts, design details and calculations, creating 3-D models, creating and releasing drawings, as well as interfacing with analysis, marketing, manufacturing, and end-user personnel. <br>
CAD software enables <br>
• Efficiency in the quality of design <br>
•Increase in the Engineer’s productivity<br>
•Improve record keeping through better documentation and communication </strong> </p>
<h4 id="Abstract">Types of CAD Software</h4>
<p style="justify-content: center"><strong> CAD or Computer Aided Design software was introduced in the late 1960's to expedite engineering drawing process. While CAD is used mainly in engineering drawing and construction architecture, it can also used for other purposes. <br>
There are various flavours of CAD available today and there are different methods of classifying them. <br>
• Raster 2D Design <br>
• Vector 2D Design <br>
• 3D Design <br>
• Animation <br>
• Rendering, Simulation <br>
</strong> </p>
<h4>Raster 2D Design</h4>
<p style="justify-content: center"><strong> It is a dot matrix data structure which represent reactangular grid of pixels. Ratser image
save in image file with different format. To draw the raster 2D design I have used KRITA and GIMP </strong></p>
<br> <br>
<h4>1. KRITA Software</h4>
<p style="justify-content: center"><strong> KRITA is a open source painting software. It is used for concept art, texture and matte painters, <br>
illustrations and comics purpose. It is also used for digital painting and animation purpose. </strong></p>

<h4> 2. GIMP Software</h4>
<p style="justify-content: center"><strong> It is a GNU Image Manipulation Program. It is used for photo retouching, image composition and image
authoring. I have installed GIMP 2.10.14 software. Here i have editing the picture of my sister by using ajust color curve, brightness and

<h4> Vector 2D Design </h4>
<p style="justify-content: center"><strong> It is defined in terms of 2D points, which are connected by lines and curves to form polygons and
other shapes. Each point has a defined position on x axis and y axis of the work plane.Coreldraw, Inkscape,FreeCAD such software is used for vector 2D design.
In this assignment. I have tried all this for to draw given diagram. </strong></p>
<br> <br>
<h4>1.Coreldraw Software</h4>
<p style="justify-content: center"><strong> It is a vector graphics editor developed and marked by Corel Corportion. It is used for
• New non-destructive effect for bitmap and vector object <br>
• To control object, layers and pages <br>
• To improve pixel workflow for pixel perfect documents <br>

<h4> 3D Design </h4>
<p style="justify-content: center"><strong> The product has three dimension i.e. height, width and depth. 3D modelling is th process
of creating a 3D representation of any surface or object by using polygons, edges and vertices in simulated 3D spaces.
In 3D modelling movies animations and video gamesalso created.<br> Different tools are used for 3D design. In this assignment
I have tried to develop my project 3D model using FreeCAD and Solidwork. </strong></p>
<br> <br>
<h4> 1. FreeCAD Software</h4>
<p style="justify-content: center"><strong>FreeCAD is a multiplatform (i.e. Windows, Mac OS and Linux platform) and it is open source software.
It is general purpose 3D CAD modelling applications made for to design real life object <br>
Parametric modelling ia a type of modelling where the shapes of the 3D object are controlled by parameters. This parameter has been modified
at any times even after the object has been created.<br>

designers quickly sketch out ideas, experiment with features and dimensions, and produce models and detailed drawings.
SolidWorks allows users to create, simulate, publish, and manage 3D models. The technology intends
to make engineering processes more efficient with tools for conceptual design, product layout, strength and dynamics analysis, and more.<br>

<h4> What i learn? </h4>
<p style="justify-content: center"><strong>
1. Now I am able to draw and edit the Raster 2D images by using KRITA and GIMP. <br>
2. GIMP is very comfortable for editing digital or photo/image/graphics. It is a free alternative to Photoshop.
Gimp has its roots more deeply rooted in that territory. <br>
3. KRITA is more art (as in drawing, painting, etc.) focused. The layout is much less complex in KRITA compared to GIMP.
KRITA is comfortable for art related purposes, such as making comics, digital paintings, etc. <br>
4. In short, think 1. GIMP- photography/image/graphic editing.2. KRITA- Comics/manga/drawings/paintings. <br>
5. For Vector 2D design I have used CorelDRAW and Inkscape software. Inkscape is free and open-source vector graphics
software that allows us to craft a range of graphic design such as logo, icon, illustrator, web graphics, and so on.
CorelDraw is a vectors graphics application by the Corel Corporation. It is commercial software. I feel more comfortable in Inkscape.<br>
6. For 3D design, I tried FreeCAD and Solidwork. FreeCAD is open source and Solidwork is commercial software.
FreeCAD is somewhat typical but as we make the practice, it will get easy. Solidwork is easier to operate,
the visual effect is also very best. <br>
7. I feel more confirmable in FreeCAD now.</strong> </p>
