2. Computer Aided design¶

Assignment:¶

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 design software¶

RASTER SOFTWARE : GIMP software¶

To create the raster graphics, we used GIMP, a free, open source raster graphics editing program. GIMP is specially designed for image retouching and editing, free-form drawing, conversion between various image formats, and more specific tasks.

For this apprenticeship, we’re going to design a logo for our final project.

FIRST STEP : Installation¶

Installation is straightforward…

we need to :

Download the Windows installer .exe file from the official GIMP website , then run the installer.
Enter “download GIMP” in your browser’s address bar and select the first available link. Follow the instructions in the image below to download the software.

Finally, let’s launch the installation file and follow the various installation guides.

After installation we can begin our work.

SECOND STEP : Open gimp¶

Open GIMP Go to File > New as shown below and click OK.

We should have the following display for easier GIMP use.

THIRD STEP : Software design ¶

Depending on the task we want to do, we can use the default white sheet or a transparent layer.

A blank layer is displayed in our workspace, and it is necessary to remove it depending on the task we want to perform. Next, introduce a new transparent layer which we can name identically to the layer we’ve just removed.

Once we’ve removed the blank layer, we’re ready to start designing. To begin, we need to insert a new layer following the instructions illustrated in the images below:

rename layer > OK

Now we can get started…🍀

We have this layer, we can hide the background or not - in our case, we won’t.

We’ll draw a circle and fill it in.

To fill it in, we need to choose a pattern from all those available and then…

To fill, go to edit > fill with a pattern

Result

We repeat the same process to build a circle in our first circle.

And we fill it with white so that it’s empty

We repeat the same steps to draw an empty circle on one side of our circle

We’re going to delete the sides of our circle with the following steps.

Result

We’re now going to add some text. Click on the A icon. We can choose the form of our text.

Result

FOURTH STEP : Save ¶

To save click on file > save > OK

WE HAVE FINISHED 👏👏👏👏

VECTOR SOFTWARE : INKSCAPE software¶

To create vector graphics, we opted for Inkscape.

Inkscape is a free, open-source vector graphics editor, particularly suited to the creation or modification of vector graphics such as diagrams, logos, business cards, book covers, icons and much more.

FIRST STEP : Installation¶

To install it, simply download the Windows installer .msi file from the Inkscape website, then launch the installation.

Click on the installation package.

SECOND STEP : Open INKSCAPE¶

Now that installation is complete, we can open the software. Click on Time to draw > New document.

When you open the software, you’ll find a, page in A4 V format, to change the format, click on file. A drop-down menu appears.

For this tutorial we will create a poster of our final project.

Click on document property

We choose the format we want, or the page orientation, or we can change the page dimensions directly page dimensions

Then close the page

The result is a page like this.

THIRD STEP : Software design ¶

Now that we’ve resized our page and got the dimensions right, we can start our design.

To insert the images, click on file then on import.

Select the image to insert.

The selected image is displayed here, then click on open.

You get this page and click on ok.

To insert text, click on text. The following drop-down menu appears.

Then we enter the characteristics of our text, i.e. color, shape, font, size…

Here is the result of our work

VECTOR IMAGE ¶

With inkscape we can vectorize images and also create vector graphics. I’ll show you right away. - We’ll vectorize the image of our logo that we designed above. To do this, we’ll open our file in inkscape.

Next we go to the path tool >> then to vectorize a material object

Then we have a preview of our vector image we will click on apply to apply the model to our sheet

We now have our vectorized image on the right and our starting image on the left.

FOURTH STEP : Save ¶

Congratulations on finishing our Inkscape tutorial 👏

Oops!!! We forgot something very important save our work don’t worry this is the easiest part of the tutorial go to file > Save as shown below :

WE HAVE FINISHED 👏👏👏👏

WE’VE FINISHED WITH 2D SOFTWARE NOW WE’RE MOVING ON TO 3D 👏👏👏👏

3D design software¶

3D SOFTWARE : FUSION 360 software¶

Welcome to this section,

3D modeling is the computer process of creating a three-dimensional digital representation of objects or environments, characterized by geometric data such as spatial coordinates, textures and visual properties, using specialized software for visualization and analysis in diverse applications such as animation, simulation, industrial design and video games. Fusion 360, developed by Autodesk, stands out as an integrated solution, offering outstanding functionality for the creation of three-dimensional models. In this exercise, we’ll explore some of Fusion 360’s features for 3D modeling,

For our training on Fusion 360, we chose to design a small cube with a hole and a chamfer.

FIRST STEP : Installation¶

For the installation of fusion 360 we used the free version as shown below…

Download complete, we can now open the software.

Once the software is installed you just have to create an Autodesk account to use it with the free version.you should have the display below…

SECOND STEP : Open FUSION 360¶

THIRD STEP : Software design ¶

Now that we’ve finished the basics, we can begin our work…🤗

Select the rectangle tool. Then go to the grid page. We mark the first point of our rectangle by left-clicking on it, then move our mouse. To define the size of our rectangle, we can enter values as shown below. Then click on the green FINISH SKETCH button.

We’ll now shape our cube using the extrusion function.

Let’s move on to our drilling.

To do this, we click on one of the surfaces of our cube and then click on sketch.

Click on the circle tool, then on our previously selected face. Draw the circle, then click on the dimensioning tool to give our circle a dimension. Click on Finish to exit sketch mode.

We select our circle, then click on the drilling function and enter a dimension, or more simply on the extrusion function and enter a negative dimension.

To create the chamfer, follow the same steps as before and click on edit, then on chamfer, then on our sketch and finally we give a dimension to our chamfer.
