# 2. Computer Aided design

This week we learned about 2D and 3D design, and you’ll see simple tutorials for each app illustrating a short journey I’ve had this week There are plenty of websites and apps to create 3D and 2D models

2D models¶

adobe illustrator¶

Adobe Illustrator is the industry standard design app that lets you capture your creative vision with shapes, color, effects, and typography. Work across desktop and mobile devices and quickly create beautiful designs that can go anywhere—print, web and apps, video and animations, and more.

lets create a yin & yang symbol 1. from the toolbar choose ellipse tool 2. click alt+shit to create an even circle 3. copy the shape and use scale tool , inter , type 50% as the shown picture 4. copy the smaller circle again and scale 20% 5. select the both circles , duplicate shapes select all , on object tap expand 6. use shape builder tool to join the shapes 7. change the color to black and join the other half click here

cuttle¶

A vector editor with features for cut design like live modifiers, parameters, reusable components, scripting, the nice thing about it is that it is online, so you don’t need storage space to download it

Let’s start with the interface

To draw lines, use the Pin Tool Mirror Duplicate is a good tool for duplicating identical shapes

Now we can define the shape and apply the rotation rate

After applying the rate

To give the lines some thickness, select the stroke

You can choose cap stroke (round / butt / straight)

to change colors

Sometimes a project needs more than one layer so you can duplicate and add layers as you like Change the color to your favorite And add another layer Need to print your work? Use the layerd stack modifier So you will only get the outline of the strokes for lasser cutting export the file as svg click here

3D models¶

fusion 360¶

To start fusion 360 is an insanely complex, stupendously powerful program. That makes it a little hard to approach and even harder to master. Despite this, it is powerful and useful, so it is important to learn to use it

When I tried to download Fusion 360 for education license it didn’t work for me so I switched to the second option with an amateur user but it is a limited edition so there are features excluded,

The impressive thing is that it downloaded very fast

This is the interface of Fusion 360, to start creating a new design click on the file

One of the mistakes I made for learning fusion 360 was that I jumped too high without learning the basics, I was trying to make flat furniture but it took a lot effort, I was copying it without knowing what to do

Even it was a wrong thing to do , I have learned new cool things like the parallel tool that constrains two lines so that they extend in the same direction and never intersect.

I also learned about parameters to create and manage equations and relationship to control the size of objects

After searching on google, I found a great guy who teaches Fusion 360 His method of teaching is very simple and shows you everything step by step

link to the playlist

In the first lesson of the playlist the task was to practice (fusion 360) to create 3*3 in specific size rectangles with a distance of 25 mm As Paul Mcwhorter said the first key to success in fusion is be mindful of your ribbon you have to sort tell it what to do then do it Useful shortcuts to work easier

(d=dimension)(r=rectangle)(l= line)(c=circle)(t=trim)(m=move) (x=construction)

In the second lesson I tried to make a cover that can be used for glasses, pencil or anything else We start with a rectangle and dimensions of 42 * 32 mm

I used the fillet tool to smooth out the edges by creating an arc in the edge and you can measure the radius of the arc.

Another tool, the offset tool, was used to copy the drawing at a specified distance from the original object I set the deminsion to: -1mm and: -2mm so I got 3 parts

If you want to copy the entire object instead of copying and pasting it, you can use the rectangular pattern, which allows you to choose the quantity in rows and columns and the distance to be copied based on the information typed

To turn this 2D shape into a 3D object, we can add depth using the extrude tool I add 3 different lengths to each part to be able to close the case

This is the final look
