2. Computer Aided design¶
Week02 – Day 1: Introduction to Raster, Vector, and Cuttle.xyz¶
This day was focused on understanding the differences between raster and vector graphics, as well as learning about key tools and file formats used in the design and fabrication process. The aim was to distinguish between these two types of images, learn their specific applications, and explore tools for working with 2D and 3D designs. We also explored CAD (Computer-Aided Design) platforms like Cuttle.xyz and had a brief introduction about Fusion 360, as well as understanding how to use different file formats for laser cutting, CNC machining, and vinyl cutting.
Key Concepts and Terminology¶
- What is Raster?
- Raster graphics are made up of tiny individual pixels, each with its own color value. These images are resolution-dependent, meaning that they can lose quality when resized or scaled.
- Common raster formats include JPEG (JPG) and PNG
-
Uses: Raster images are most appropriate for photographs, textures, or complex images where details and color gradation are important.
-
What is Vector?
- Vector graphics are created using mathematical formulas, involving points, lines, curves, and shapes. Since these images are based on formulas rather than pixels, they are resolution-independent—meaning they can be scaled infinitely without losing quality.
- Common vector formats include SVG, DXF, and PDF.
- Uses: Vector graphics are ideal for logos, illustrations, blueprints, schematics, and any design work that needs to maintain sharpness at different sizes such as laser-cut designs and CNC.
Difference Between Raster and Vector - Raster images (JPG, PNG) are pixel-based, and thus, resizing or stretching them can lead to pixelation or blurriness. - Vector images (SVG, EPS) are resolution-independent and maintain sharpness and clarity no matter how much they are resized.

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
}
