Tools Used

Sketchup

  1. Download
  2. Transfer to Application Folder
  3. Now Open it to use.
  4. Select Template.

Layout ot Sketchup

Tools



Line Tool Arc Shape

It have many other tools but this are basic one.
You need to go through Tutorial Basics for better understanding tools.
Now making a Sensor Box You need to use tools.
I am going to use Rectangle tool to make a Box

I am going to use screen Recorder to record screen and upload to Youtube
How to record video on Mac OS check http://osxdaily.com/2010/11/16/screen-recorder-mac/

Fusion 360

  1. Download Fusion 360 | Link Education Version
  2. You need to have a Account on Autodesk Student they will mail you License key to your mail id
  3. Install Fusion 360 it will take time wait so install when you have 60 min ( It may create problem if setup is interpreted in between)
  4. After that copy paste License key and its done
  5. Check Below Tutorial for basic operating and commands of Fusion 360
I am going to make a simple holder for Ultrasonic Sensor which have Neodymium Magnet at base so it can easily fixed on any magnetic structure.

Ultrasonic Sensor Magnetic holder

  1. You need dimensions of Ultrasonic sensor to start with designing a CAD Model
  2. I googled ultrasonic sensor dimensions
  3. You will get such a image with Dimension or you have to use Vernier
  4. Now you have each dimension so now start with 2d and converting that to 3d.

Using Fusion 360 for Ultrasonic holder

  1. Open Parametric Modify > Change Parametric > Add ( Click on Green Plus)

  2. Add Dimension to Parametric So you can directly add.

  3. Now go to Dashboard and Go to Sketch > Line ( Put a point stretch and enter "endtoend" it will automatically take Dimension 41.7 as it is in Parametric
  4. just go Sketch > select Circle >with 2 point
  5. Put on end of line and stretch and enter value diameter it take 16.3 automatically

  6. Now Make it 3D create Rectangle and extrude ( I have Video to explain this check it below)
Problem Faced
  • Understanding Dimensions and Desgin ( so for Beginners Sketchup is Easy to understand 3D and to practice without Dimension )
  • Subtraction and assembly will take time so at least 3 to 4 different objects is to be made for a better learning and grip.
  • Going to Record Video and trim to make it final one
  • Trying to make Videos and Content in Local Language
  • Size Reduction of Website by GIF making to explain process
  • Next time going to use proper theme
  • Work management is important as Documentation take at least 3 hour( Take Screen shot at process it saves time )

Output

  • Learned new design software like Gimp, Inkspace and Fusion 360

Some Quick Points

  • I like Illustrator and Photoshop but you should learn more software that have certain good fetures
  • I learned default editors available in Mac Preview Option , which I was not knowing before
  • Shortcuts are easily availables from youtube and Google, it make you faster
  • Many software are now getting on cloud, it is important if you can learn how to manage that.
  • In this week I realise to use Student email address to avail many free tools and services by using it as student for free
