1. Week 2¶
Hello everyone, documenting what you learned and worked on in week 2 of Fab Academy. The main assignment for the second week was to explore a variety of 2D and 3D design software. In the first session, we learned the difference between two types of graphics, raster and vector. In simple terms, bitmap images consist of an array of pixels, while vector images consist of paths, the difference between which is clearly visible when the image is enlarged. The picture below shows the difference between the two types.
Now, I’ll talk about my experience with each program I tried.
Cuttle.xyz¶
cuttle.xyz is a 2D design program. I think it is very easy to use, and helps in engineering designs. It will be a great option if you want to design a slogan or simple drawing, for example. This is a very simple drawing that I created, I was tampering with the tools available in the program and trying different settings, but only for simple designs.
Here I used Boolean union (weld)

Fusion 360¶
Fusion 360 is a 3D and 2D design program. The projects you can create on this application are limitless. There are lots of tools and settings you can choose from, lots of objects you can insert. You get to specify the dimensions of the objects you want to create. It needs lots of practice, due to the amount of functions it has, but it is simple and easy. For now, this is one of the first sketches I made on Fusion 360.
Here was the 2D Design experience
Here is the experience of converting it to 3D Design by going to MODIFY>MOVE/COPY (M)
The final form in 3D Design
In conclusion, my experience with fusion360 was in 2D and 3D design, and it was a very enjoyable and easy experience, especially in moving from 2D to 3D with shortcuts, which saves time and makes drawing the opposite direction faster.

Another design - 2x8 Block
The first we choose the square in the arrow and put the sizes of the square in the vacuum in the circle
Choose the extrude tool to determine the thickness
You’ll get this look
Choose a circle and determine its area
By choosing “Sketch Dimension”, we determine the distance of the circle with the body by writing the distance we want
Choose “rectangular pattern” to branch the selected part
To become like this
We go to the bottom, choose the shell, and write the size we want
To become like this
From the “line” option, we select the two points to define half of the cube
Make a circle in half in the required size
From modifi, we choose offset to branch the circuit
We drag them as we did above and write the required size
And we adjust the corners of “fillet”
To become this final form

Tinkercad¶
Tinkercad is a simple and easy-to-use 3D modeling software, ideal for beginners and hobbyists. It features an intuitive user interface and easy-to-learn tools, making it ideal for creating 3D models for various purposes, such as:
Tinkercad is an essential tool for designing models that you want to print on a 3D printer. You can design anything from small jewelry to intricate toys and useful household items.
blender¶
Now I am in the process of experimenting with a fourth program, which is Blender. What I read about is Blender, which is a free and open source program for 3D design. It is distinguished by its tremendous capabilities and its ability to compete with large commercial programs. Whether you’re a beginner or a professional, Blender gives you all the tools you need to create, animate, and render stunning 3D models. Blender: Your Free and Powerful 3D Creation Suite Blender is a free and open-source 3D creation suite that empowers you to create stunning 3D graphics, animations, and visual effects. It’s used by professionals and hobbyists alike for a wide range of applications, including: -3D Modeling: Create intricate 3D models for games, animations, and visual effects. -Animation: Bring your models to life with realistic and dynamic animations. -Simulation: Simulate physics, fluids, and other natural phenomena. -Rendering: Create photorealistic images and animations. Video Editing: Edit and composite video footage.
Epic Games¶
We downloaded Epic Games and registered
“Epic Games Launcher” is a free program that allows you to download and install games from the Epic Games Store. Provides an easy-to-use interface to manage, update, and play your game library.

Code Example¶
Use the three backticks to separate code.
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
