Computer aided designing


3D design-

I used 3D design software before fabacademy also.So,I had little bit knowledge about it but yet I am not superior into that.I had decided to do 3D model of my project.I go through different designing softwares .Which are,

Tinkercad
Solid works
123D Design

Tinker cad is online software , continuous and good internet is required.When I was designing it taken much time for loading.I realize that if we want to design small part then tinker cad is okay but as I was going to design complex structure I rejected to use it.

As per my experience Solid works  is very good design software.I made below design within few minutes.But I am not superior into it.As I had decided to make 3D model I prefered 123D design


Solid works
SolidWorks currently markets several versions of the SolidWorks CAD software in addition to eDrawings, a collaboration tool, and DraftSight, a 2D CAD product.  
We require license for using this
Has many functionality than 123D design 
Easy to use
We can save model in different file formats
Able to make 2 D design
Recommended for 3D

Limitation -It is only able to operate on windows 


Then I tried for making project model into that.I made 3D design by using 2D shapes
I tried for making same model with 3D shapes.Like below

In solid works we have to take  separate planes to draw any thing on the plane which we have not defined previously while designing.

123D design-
This is user friendly software.SoAnyone can do designing easily using 123D design.  It is
Open source
Has many functionality 
Easy to use
We can save model in different file formats
Able to make 2 D design
Recommended for 3D

Limitation -It is only able to operate on windows 

Then I go for 123D design software.It is free software and I enjoyed designing while using that.It very easy and user friendly software.But we can't use this software on ubuntu.I wanted to design below model

       
         

step1- You can download this software on your system.Install software and start designing.As sketch was infront of me I started from making below part of design.Take the shape you want from provided basic shapes
step2-Arrange shapes as per you requirement by using  commands like move,subtract,merge,smart scale.These commands are very common and important to design any model.

step3- Group the parts together if you want to move the things together.                                              

step4- Arrange everything and give different colors and texture you want.                                         

step5-Now our final model will be ready.This is my project model.   
                                                                                           










2D design-

For 2D designing I used Inkscape.Inkscape is a professional vector graphics editor.Inkscape has sophisticated drawing tools with capabilities comparable to Adobe Illustrator, CorelDRAW and Xara Xtreme. It can import and export various file formats, including SVG, AI, EPS, PDF, PS and PNG.
Initially I made simple designs for being comfortable with the software.First time I made some triangular structure like below.




Then I tried for making 2d design of project model.It is as below




After this I go for designing of 2D parts required in my project.step1-Pick object you want and start designing






step2-I wanted to make notches.so I searched for that on internet but I don't found useful results. so I made chain of rectangles by adding rectangle one by one and replicate it by grouping first and then copying where it is required.





step3-Then I extended the size of rectangles which I want to remove.Because when I was not extended them that time I was unable to remove unwanted part.I used boolean operation ,differenceto subtract unwanted part.
























step4-After taking difference I removed all rectangles taken initially.I have made this design for hanging the stirrer above the pot.





Things learnt -This assignment was helpfull to learn 2D and 3D design.While doing this assignment I go through various 3D softwares,their tutorials and read others reviews on design tools.After learning 2D and 3D deign,I teach designing to school students and makers through workshops.
