Week 02

Computer Aided Design

This week, we learned to use new tools for both 2D and 3D modeling. We also compared how each tool works and analyzed which ones best suit our workflow.

TOOLS

Shapr3D, Onshape, Illustrator, Affinity

3D Modeling Exploration

The assignment for this week was to 3D model our possible final project or a piece from it in two different softwares in order to compare. Also to model something in the 2D software that could be useful for our final project.

Shapr3D: Intuitive iPad Modeling

Shapr3D is an intuitive, professional 3D CAD modeling application designed for iPad, Mac, and Windows, allowing users to create precise, manufacturing-ready models.

Step 01

01. Mobile Sketching

I started by adding basic shapes, modifying it, only working on one side of the sketch, to mirror it to keep the design symmetrical.

Step 02

02. Sketch Development

Once the main shape was defined, I continued adjusting the sketch, refining proportions and details until I had the complete form.

Step 03

03. Extrusion

I extruded it to create a solid piece, turning the 2D sketch into a three-dimensional object with volume.

Step 04

04. Internal Space Definition

I extruded and sketched the areas where I needed to create internal space, defining openings and functional areas without affecting the external shape.

Step 05

05. Material Application

Once the geometry was finished, I added materials to the model to visualize how the final piece would look.

Step 06

06. Final Review and Export

After checking measurements and details, the model was ready to be exported.

Onshape: Cloud-Native CAD

Onshape is a PTC-developed cloud-native 3D CAD, CAM, and PDM software-as-a-service (SaaS) platform that runs entirely in web browsers and on mobile devices.

Onshape Planes

01. Defining Planes

Here you'll have the option to choose in which plane you'll start sketching.

Onshape Sketch

02. Sketch

You can start sketching until you have your desired shape.

Onshape Extrusion

03. Extrusion

Here you'll have the extruded piece with fillets.

Shapr3D vs Onshape

After working with both tools, I found Shapr3D to be more intuitive, user-friendly, and faster for creating organic shapes and quick prototypes. Its touch-based workflow makes the modeling process feel natural and easy to understand.

Onshape, on the other hand, is a powerful parametric CAD platform with strong engineering capabilities and precise control. Although it has a steeper learning curve, it becomes a very useful tool once you understand its logic and structure.

Rendering Process

Applying Materials

01. Applying Materials

Here you can choose from the variety of materials and colors.

Environment

02. Environment

You can choose which environment you want and play with the angles.

Generative AI Render

03. Generative AI Render

Use a prompt to generate a render with AI from your model.

2D Modeling

Adobe Illustrator

Adobe Illustrator is a vector graphics editor and design software used to create precise vector graphics for digital fabrication.

Path finder

01. Import and Path finder

After you've imported your img you need to click on path finder.

Select kind

02. Select kind

You can choose in which style you want to vectorize it.

All done

03. All done

You can start modifying your image.

Affinity Designer

Affinity Designer offers professional vector editing capabilities with a smooth performance and a clear workspace.

Import image

01. Import image

Initial image was imported into the workspace.

Vectorizing

02. Vectorizing

Curves and nodes were adjusted to achieve smooth and accurate geometry.

All done

03. All done

The vector is ready for further editing or export.

Illustrator vs Affinity Designer

Since I have worked with Adobe Illustrator for a longer time, it is the tool I understand best and feel more comfortable using. Affinity Designer, however, is also a powerful tool that proves to be a solid alternative for professional vector design once you become familiar with it.

Image Compression

Mac Quick Actions: Convert Image

macOS includes a built-in Quick Action to convert and compress images directly from Finder, without needing any third-party software. It supports conversion between formats such as JPEG, PNG, HEIF, and more.

Select image in Finder

01. Select the image

Right-click the image file in Finder to open the contextual menu.

Open Quick Actions

02. Open Quick Actions

Hover over "Quick Actions" in the menu to reveal the available options.

Convert Image option

03. Convert Image

Select "Convert Image". A dialog will appear to choose the format and image size.

Choose format and size

04. Choose format and size

Pick the output format (e.g. JPEG) and the desired resolution — Small, Medium, Large, or Actual Size.

Compressed file saved

05. Save

The converted file is saved automatically in the same folder as the original, ready to use.

Why use it?

This tool is ideal for quick, lightweight compression without leaving Finder. It requires no installation and handles batch conversion by selecting multiple files at once. For more advanced control over quality and file size, a dedicated tool may be preferable.

Video Compression

FreeConvert: Online Video Compressor

FreeConvert is a free online tool that allows you to compress video files without installing any software. It supports a wide range of formats including MP4, MOV, AVI, and MKV, and gives you control over quality settings.

FreeConvert website

01. Go to FreeConvert

Visit freeconvert.com and navigate to the Video Compressor tool.

Upload video

02. Upload your video

Click "Choose Files" or drag and drop your video. Files up to 1 GB are supported on the free plan.

Adjust settings

03. Adjust settings

Set the desired output quality or file size target. You can also change the output format if needed.

Compress video

04. Compress

Click "Compress Now" and wait for the process to complete. Processing time depends on file size.

Download result

05. Download

Once done, download the compressed file. Files are deleted from the server after a short period for privacy.

Why use it?

FreeConvert is useful for reducing video file sizes before uploading to a website or submitting documentation, without affecting the visual quality too much. Since it runs in the browser, no installation is required and it works on any operating system.
