Weekly Assignments Final Project About me

2.Computer Aided design

Week two really seems like a heavy week with lots to do and play with differnet software. We are required to try many softwares and experience with it to select the one we are confortable to do it and we need to explore further by ourselves.

Assignment of the 2ndweek

Model (raster, vector, 2D, 3D, render, animate, simulate, …) a possible final project, compress your images and videos, and post it on your class page.

Task For Week 2

  • 2D DESIGNING and EDITING: Raster vs Vector.
  • 2D softwares.
  • 3D CAD softwares.
  • Rendering and Animation of CAD design.
  • Learn how to compress image and video size using different softwares.

    • 2D Design

    A 2D drawing view is a representation of a 3D CAD part or assembly that is placed on a drawing sheet. A drawing view represents the shape of the object when viewed from various standard directions

    2D Design are 2 types

  • Raster Design
  • Vector Design

    • Raster Design are those made of pixels, or tiny dots that use color and tone to produce the image.

    Vector designs are those consist of anchored dots and connected by lines and curves. As they are not based on pixels, they are also known as resolution independent, which makes them scalable and device independent.

    Vector Vs Rastor

    Difference Between Vector and Rasteer

    Work flow of Raster and Vector

    In this I have used inkscap software to generate a file and vectorize from rastor.

  • Open Inkscape >> upload raster png file >> click on yor image and clik on Trace Bitmap
  • Increase the Brightness cutoff >> Update and click on Apply
  • Finally here is my Rastor to Vector image.

    • Raster Image

    As google mention, Raster images are generally what you think about when thinking of images. These are the types of images that are produced when scanning or photographing an object. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image.

    Since raster images are pixel based, they are resolution dependent. The number of pixels that make up an image as well as how many of those pixels are displayed per inch, both determine the quality of an image. As you may have guessed, the more pixels in the image and the higher the resolution is, the higher quality the image will be

    Here are some example of raster image editor that i have used with inbuilt image editor from window 11. In this image editor, it has many opting to change the;

  • 1. Image contrast
  • 2. Brightness
  • 3. Auto Enhance
  • 4. Pen editor with higleter mark

    • Here are some pictures to show you all:

    Image/Video Compression

    As we are aware from the last class on Thursday,we need to always compress our Images before pushing into repo so i have used Xnconvert Software as I am more comfortable and easy to use with the Xnconvert.

    Compressing Using xnconvert Sofware and Online CAESIUM Image Compressor.

  • Open xnconvert >> under input tab click on add files.
  • After adding Image file >> click on add action and select image >> click to resize.
  • Under the output tab, you can select new file name, file directory etc and Hit on convert.
  • Here is your image sizes under status

    • Online CAESIUM Image Compressor

    Caesium Image Compressor is a free image compression application that allows you to compress your pictures up to 90% without visible quality loss. This tool is suitable for photographers,webmasters and businesses users that seek high flexibility image compression. It supports all types of images starting from JPEG, PNG, GIF, BMP, and WMF.

  • To compress any Image file, you can click on this link CAESIUM Image Compressor
  • Click on Browse >> Selecte your image file to compress
  • Under option, i have decress the quality and done the compress.
  • After you compress check the image file size as given below and Download it.

    • Video Compression

    3D Design: Fusion360

    Fusion 360 is a cloud-based 3D modeling, CAD, CAM, CAE, and PCB software platform for professional product design and manufacturing. For fabacademy, we were granted education license for fusion360 by the fab foundation. Therefore,I have installed fusion360 from here for the 3D designing tool. To go on this, first go into Autodesk website and sign in using your email that is linked to Fabacademy by clicking the “forgot my password”. Once login is complete, sign into fusion360 with the same email and you should have “education license” active.

    In Fusion360, I am going to design a simple key hander with different tools and options. As I am alerdy familer with Fusion360 3D software from pre-fab academy so i have decided to work on this.

  • Open your Autodesk Fusion 360 software and Creat sketch point X & Y.
  • Creat a rectangle shape from the middle point as given below. Mark your length and hight of the shape in mm.(L-200 H-100)
  • After that, Click on Extrude to creat depth in your design and give your distance in mm (2mm)
  • Select all the conner point to make it fillet (Round Edges) by giving 3mm radius.
  • To make hole in your shape, click on hole option to create a hole as given below.
  • To add text in your design, go to Create option and click on tex. You can play with the virus options like front size, front thems and etc.
  • select on your text to make press pull for your design to make more atricative as given below:
  • finally save your design and export in .stl or .f3d file formate.

    • 3D Design: Thinkercad

    Tinkercad is a free web app for 3D design, electronics, and coding. We're the ideal introduction to Autodesk, a global leader in design and make technology.

    In this thinkercad I have design a simple house with 3D design.

  • 1. I have drag a box and created with (hight-40, width 60 and depth-30) and i have copy the same box and then clicked on hole and change the demission (hight-36 width-56).
  • 2. Select the design box and then click to align and clik on group to cut down as given below:
  • 3. Now click to workplan tool or type letter W >> select the box and drang in to make a door with a rectengale shape and click on group to cut it down as done below:
  • 4. Select workplan tool or type W and place where to make a window shape and group it as done here
  • 5. Finally to make rooftop,select workplane >> choose roof shape >> drag it into your workplace >> rotate into 90 degree and adjust to fill your roof top.

    • Video Compressing

    As a IT person I am more familer with MP4 editor software so in this assignament i have used Kdenlive to compress my MP4 size. Link to download Software.

    Kdenlive is an open source video editor. The project was started around 2003. Kdenlive is built on Qt and the KDE Frameworks libraries. Most of the video processing is done by the MLT Framework, which relies on many other open source projects like FFmpeg, frei0r, movit, ladspa, sox, etc…

    I have compressed the animated video which was created using fusion 360. Initially the video size was 9.7 MB.

    Now to compress the video, I have draged and dropped my video in Kdenlive and put it in the timeline. Now click on the Render from project dropdown menu and select the more option button. Select the Rescale button and make sure to preserve the aspect ratio and clicked the render to file option.

    Now here we can see the compressed file size before and after.
