W2 | Computer-Aided Design ✍
INDIVIDUAL ASSIGNMENT
- This week, I compared different 2D and 3D design software. Some I have used frequently before, while others are new to me. My goal is to find the most suitable tool for developing my final project.
- Model (raster, vector, 2D, 3D, render, animate, simulate, ...) a possible final project, compress your images and videos, and post a description with your design files on your class page
2D
CorelDRAW X7
When I took the Digital Fabrication Processes course at university, we learned to use CorelDRAW,
but only as a bridge to import DXF files from Inventor. The reason? It was compatible with the laser cutter
we used for our projects. At first, I saw it as just a conversion tool, but over time, I realized it had
much more potential.
One of my favorite features is Bitmap to Vector, which allows me to convert JPG or PNG images into editable lines-perfect
for creating custom pieces.
- Some designs that I did using CorelDRAW X7:
In the lab, we had a basic design from Victor, but I was requested to improve certain features to ensure the charging cable wouldn't be an issue. After several tests and prototypes, I came up with a more functional version. The result was so good that I ended up receiving orders for 50, 100, and even 250 units for different university events. It was crazy 😂
🐿️ Chuwi Keychains - ESAN's Andean Squirrel
For another project, we had to fabricate something representative of the university as a giveaway for students. ESAN's mascot is Chuwi, an Andean squirrel, so I thought, why not turn it into something cute and practical?
The result: I designed custom keychains featuring Chuwi. 😊
Chuwi, chuwi, chuwi
🎨 ID Badges for Fab Academy Bootcamp 2025Another design I created in CorelDRAW was the ID badges for the Fab Academy Instructor Bootcamp 2025. Fab Lab ESAN was the host for this event, I designed these badges to welcome our guests and keep everything organized. 📋
These identification budgets were for the staff
3D
Autodesk Inventor 🆚 Fusion 360 ⚔
I have some experience designing with 3D software, but the one I've used the most is Autodesk Inventor. During my engineering courses, learning this software was essential. Over time, I got the hang of it, and while I still have a lot to learn, I've gained solid experience. Inventor has allowed me to create animations, assemblies, and different kind of models.Then came Fusion 360...
When I started working at the Fab Lab, Jorge kept saying, "Fusion is better!" At first, I didn't believe him (and honestly, I still don't fully agree, haha). But I must admit, while both softwares have similar interfaces, Fusion has surprised me. Some designs that required me more time in Inventor were much faster and more intuitive to create in Fusion.
Each software has its strengths, but in the end, the best one is the one that gets the job done efficiently. I guess Jorge wasn't completely wrong... maybe. 🤭
So far, I've experimented with the following designs using these softwares:
🍬 Candy Dispenser: My First Digital Fabrication Project
One of the most complete projects I've ever worked on was a candy dispenser. This was my first real dive into the world of digital fabrication, and I was instantly hooked. Through this project, I got to explore so much more—I discovered the Fab Lab, learned about the incredible projects being developed there, and experienced firsthand the endless possibilities of digital fabrication.
Autodesk Inventor 2023
🐼 Trying Fusion 360: A Panda Pencil HolderI was curious about Fusion 360, so I decided to give it a try. One of my first projects was a pencil holder—but not just any pencil holder, a panda-shaped one! Compared to Inventor, Fusion felt more intuitive and enjoyable. The interface was smoother, and tasks that used to take me longer became much easier. With this project, I explored Fusion's tools and saw firsthand how powerful and flexible it is. There's still a lot to learn, but this was just the beginning. And honestly? I'm excited for what's next!
So… was Jorge right? Well, let's just say I'm not ready to admit it yet—but Fusion definitely won me over! 😃
This is the Fusion 360 online viewer—super helpful for staying within GitLab's file size limits!

Generative IA
🤖 Designing with Generative AI: Chuwi in 3DChuwi is ESAN's mascot, and I wanted to 3D print a model of it. I reached out to the original designers, but unfortunately, they didn't have a 3D version available. So, I thought, why not use AI? That's when I discovered Tripo AI a platform that can convert JPG images into 3D models in STL format, ready for printing. I gave it a try, and honestly, the results were pretty good! Of course, it needed some adjustments, but overall, it was a great starting point. Tripo AI isn't entirely free, but it does give you some credits to experiment with. If you're curious about AI-powered 3D modeling, it's definitely worth checking out!

Compressing Images
For now, I've been using PowerPoint to compress my images. I still need to do more research, but so far, it's been working well. PowerPoint allows me to resize my images and significantly reduce their file size from megabytes to kilobytes. What's surprising is that the quality remains good!I still need to explore more programs for video compression, but for images, this method is working great.
