Week 2 assignment: Computer-Aided-Design

Summary

This week I had to work an image using a software Raster and Vector, and a 3d model of my final project in a software for that. For the raster software I used Adobe Photoshop and for the vector I used Inkscape. For the 3d model, I used Autodesk Fusion 360.

Raster software: Adobe Photoshop

Adobe Photoshop is a raster image editing program. I used it to work with an image composed of a grid of individual pixels. This image is known as raster image or bitmap image. It allowed me to edit my principal image, modify the image in various ways like resizing, cropping, rotating, changing resolution, and others. It is capable of opening and saving images in a variety of file formats, such as JPEG, PNG, TIFF, BMP, GIF, among others. I used a trial free version accessing the software for 7 days.

First, we open an image in Adobe Photoshop and select the part of the image we want to work with.




In this case we work with the clone tool because there are many textures in the image. To use this tool we will be selecting the part we want to clone with the Option + Click keys on the selection, then letting paste with another click on the area we want to delete.


For this we are going to help ourselves by adjusting the size of the brush and the hardness, so we can play with cloning the image.


We continued working with the clonation until the house disappeared, like the following image.


In another Photoshop worksheet we are going to open the image that we want to replace with, in this case the cabin. Here, together with the magic wand, we are going to select the image and remove the background.


Once it no longer has a white background and becomes png, we are going to select the layer and drag it to the first working hour.


Once dragged we are going to position it and with the Shift control we can regulate the size of the cabin and with the command shift move the perspective if necessary.


After that we are going to use the eraser and erase part of the cabin to make the idea that it is behind the rock, regulating the size and hardness of the working brush.




Then we are going to select the cabin to regulate the brightness and contrast of the image, since it has more light than our background image. It is important to select and apply this color change only to the cabin but not to the background image.


Once the brightness and contrast have been adjusted, we can control + E and join the layers (image layers).

After that, we were left with white spaces of the cabin that we are going to select, delete and with the clone tool, we are going to add the background of the mountain.


After that with the clone tool we are going to add more yellow flowers and garden to the floor to attach the house to the image. Finally the image looks like this. Now let's add one more element.




We are going to repeat the process now with a sheep, removing the background and dragging it to the main image. We should adjust the image to the background according to the size and perspective you need.




Finally, we got the final image after all the operations:


Vector software: Inkscape


Inkscape is a free and open source vector graphics editor for GNU/Linux, Windows and macOS. The main reason I chose it was because there is a lot of information of tutorials on the web and I could download it for free, working fine in a MacOS laptop.

The following work is about how to trace bitmap from an imported image from the webpage.
First, we have to import the image to the software to start working with it.



Then, we have to go to the option of trace bitmap. What this option does is give you a set of curves which you can use as a resource for your drawing. Our tracer, derived from the original Potrace library by Peter Selinger, interprets a black and white bitmap, and produces a set of curves.

Once we are in this option submenu, we can vary parameters such as brightness cutoff, changing the threshold in the way is better for our image. We can also invert the image, changing the white colors into black.

Also if you select the multicolor opcion, you can select how is the scan going to be performed, if you want it smoorh, stack or removing the bakground automatically.
With the option "live updates" with the check, we can see all the changes in real time and select the parameters that fit better for us.










Finally, the image can be exported in a Svg for opening it in another software for another process.

3d software: Autodesk Fusion 360


Fusion 360 is a cloud-based 3D modeling software developed by Autodesk. It's widely used in industries like engineering, product design, and manufacturing for creating digital prototypes, simulating designs, and generating documentation. As a student, I can use it for free for one year and it works very good on my macbook.

I think it is a good software that integrates several fields such as design and manufacturing, where I can manage my projects online.

Process of the design of my final project: water leak detector.

First I used the sketches to create the dimensions of the water tank and then another sketch for the support of the water pipes I will use..


I had to use tangential planes and the piping option (also called sweep in inventor) to design the piping system to be used.




Then, with the extrusion operation a volume of 4mm was generated. This volume can be set up with any material we want, like a type/color of plastic.






For the assembled ends of the pipes, I used the joint operation between components. It is very intuitive to use this option, asi it ask you what you want to and how you want to do it.



For the water leak detection system, I am going to work with 2 solenoid valves. The first will serve to close the water supply to a home or building, and will direct the fluid to a flow sensor. When this happens, the second solenoid valve will be open.





When you do not want to measure water leaks, the operation of the solenoid valves will be reversed: the first will be open and the second will be closed.



The water used to simulate leaks will return to the storage tank so that it is continuously measured, without waste.






As a final review, I like a lot the left side of fusion 360, the data panel. In this section, I can see all my projects and sort them in folders, and each modification I have done to them can be saved as a determined version, so I dont lose the track on my progress with them.
