Computer-Aided Design

Inkscape

Inkscape is an open-source vector graphics editor used for creating and editing SVG designs, I started by importing the image on the document and then going to the section stroke and go on the option to vectorize a bit map

In my first attempt I dont really know why the program didn´t work out and also didn´t gave me a preview, so I had to create a new document again and then I could go on.

When I get to use it, I gave it some tries until I finally get the version I wanted by changing some parameters the program gives to you.

For Inkscape I like how easy you can start to vectorize the image, the only thing I really don´t like is I didn´t manage to get the circles without filling the holes.

Affinity

Affinity is a professional vector and raster design software for graphic design and illustration. Here I also started by importing the image on the document but here I used the tool of stroke brush to first sketch the border of my drawing and then adjusting the lines to border my image. I did this several times until I finally obtained the form of the image.

Then I went to use the filling tool to give color to it, I also had to make a part for the blank space to fill it.

For Affinity I like the tool used for the vector, even though it takes a bit longer to vectorize the whole image, is really easy and intuitive to do it.

OnShape

OnShape is a cloud-based CAD platform for collaborative 3D modeling and version control. For the modeling process in OnShape, I started by creating the base geometry of the bracelet. I sketched an ellipse and then trimmed a section of it to obtain the desired curvature. After that, I used the ellipse arc tool to refine the contour and achieve the specific shape needed for the first part of the bracelet.

Once the main profile was defined, I created a rectangle sketch positioned at the center of the piece and used an extrusion cut operation to remove that section, generating the opening in the middle of the bracelet.

To continue with the design, I modeled the top section of the wearable as a separate part. I referenced the measurements from the first component to ensure proper alignment and proportions. Using those dimensions, I created another ellipse arc and trimmed the unnecessary segments until I obtained the intended shape. Then, I extruded the geometry to give it volume and thickness.

Next, I sketched a rectangle on the upper surface of this component and performed another cut operation to create the space intended for the screen.

For the final part, I reused the previously created rectangle sketch by copying it and extending its dimensions to fit the required proportions. This allowed me to generate the complementary component needed to complete the structure. After creating this element, I assembled all the parts to obtain the final wearable design, ensuring proper alignment and fit between the components.

In my opinion, OnShape is a very intuitive program for 3D design. I enjoyed using it and perceived it as a more accessible and user-friendly tool compared to other 3D modeling software.

SolidWorks

SolidWorks is a parametric CAD software used for mechanical design and 3D modeling of parts and assemblies. In this program, I used the measurements I had previously obtained in OnShape so I could apply a different sketching technique. Instead of relying only on basic shapes, I combined lines and curves to achieve the desired geometry more accurately.

Following a similar approach to the OnShape design, I first sketched a rectangle and worked on only half of the geometry. Then, I removed the middle section to create the internal space needed for the design.

To create the top section, I reused the measurements from the 3D model to maintain consistency across all parts. After defining the main shape, I sketched another rectangle on top and performed a cut operation to generate the opening intended for the screen.

For the final component, I copied the dimensions from the previous rectangle and extruded it to form the remaining structural part. This allowed me to assemble all the elements into a complete design.

Once the geometry was finished, I assigned materials to each part to improve the visualization and make the model look more realistic.

Since I am not very experienced with SolidWorks, the software initially felt more complex compared to other tools. However, as I continued working, I was able to achieve more precise dimensions and a more realistic design.
