2. Computer Aided Design¶
As part of my project preparation, I aim to explore software options that facilitate the digital presentation of my final project idea in both 2D and 3D formats. The initial phase will involve utilizing vector-based programs for 2D design, which offer precision and scalability in rendering graphical elements. Additionally, for the 3D aspect of the project, I plan to leverage specialized programs capable of creating three-dimensional models. Furthermore, I intend to incorporate software that enables the creation of dynamic presentations, including video rendering capabilities, to effectively showcase the digital model of my project. By utilizing a combination of vector-based and 3D modeling software, along with video rendering tools, I aim to develop a comprehensive digital representation of my final project idea.
Assignements for the week¶
- Evaluate and select 2D and 3D software
- Demonstrate and describe processes used in modelling with 2D and 3D software
Research¶
Before starting this Computer-Aided Design (CAD) week, I first conducted research on existing 2D design software on one hand and 3D design software on the other, in order to make an initial selection of the software I would like to test and use for the FABAcademy. From this analysis, two software options for each type of design (2D and 3D) emerged that I would like to test and that interested me due to their efficiency, ease of use, and user experience. These four software options are:

3D Design¶
Before I start, I create a Folder in Fusion to range and stock all the differents files I will use for my final project. It’s very helpfull when you designing a big project with many components.
My first goal was to create the structure of my robot. For that i want to use Aluminium Profile 20x20 so that I download a free 3D model of a 20x20 Profile and export it on Fusion 360 to redifine the size with my projects need. The 3D Model links is there : GrabCAD form Kaushik B. M.
Enter in the sketch function and use the project tools to project the skecth of the profile and after that you delete the object (Component) and leave the sketch
Now you have the sketch you can extrude the different size of the Aluminium profile you want. Me for my final project i only need a 300 mm & 600 mm of Aluminium profile.
You can now use the Align function to assemble the structure of your the robot. Use the shortcut s to do research and directly search for align and the click enter.
To mount and assemble my chassis i need some joints to make a solid and durable assembly of the structure. I insipre myself with this kind of existing tools and design it with fusion 360. “NB: Just looking at the photo and sketching & Extruding it”
I Finally mount and assemble all the part of the main structure of the chassis of the robot NB: I really recommend to do all the small and big parts as component to make more easy the assembly
For the wheels, I’ve chosen a honeycomb structure for the tread. This design combines strength and lightness, which is advantageous. It’s capable of absorbing shocks and provides good traction, essential features for the project’s optimal functioning, especially considering its ability to support and transport significant loads. Indeed, the robot is designed to handle loads of up to 35 kg.
2D Design¶
1. Raster (or Bitmap):
- Definition: Raster images, also known as bitmap images, are composed of individual pixels organized in a grid. Each pixel has a specific color and precise position in the image.
- Properties: Raster images have a fixed resolution and are best suited for photographs and complex images with color gradients. However, they can lose quality when enlarged because individual pixels become visible, resulting in pixelation.
- Common formats: JPG, PNG, BMP, GIF.
2. SVG (Scalable Vector Graphics):
- Definition: SVG is an image format based on vectors. Instead of using individual pixels, SVG images are composed of geometric shapes (such as lines, circles, rectangles) defined by mathematical equations. This means that SVG images can be resized to any size without loss of quality, as they are represented by vectors.
- Properties: SVG images are ideal for logos, icons, and any other graphics requiring scalable quality. They are also editable using vector design software.
- Common formats: SVG.
In summary, raster images are composed of pixels and are best suited for photographs and complex images, while SVG images are based on vectors and are ideal for graphics requiring scalable quality.
