How to make almost everything

week3: Computer-Aided Design

1. learing 2D, 2.5D design-raster:Photoshop, photoscape

I first used 'Photoshop' as an image converter. Because Photoshop is a very famous program, I knew it well.
I have never used Photoshop since I have never done photo editing.
So, this is a good opportunity to use the basic functions of Photoshop once.
Among them, we practiced reducing the size of the image we use. It was a neat job.
However, Photoshop is a program created by Adobe and is available for $ 23 a year ...
This is a disadvantage of Photoshop..

You can use Photoshop to reduce the size and capacity of your photos. But Photoshop is hard to use.

So I used the free 'Photoscape', not the paid Photoshop. Because Photoscape is open source, it is free to use.
And Korean support is also possible, so Koreans can write comfortably.
And it is very good software because you can edit several pictures at once, not just one.

The photoscape software is lightweight and easy to use. And it's free!

2. learing 2D, 2.5D design-vector:illustrator

The next tool I learned was 'Illustrator' . Illust is a very powerful tool in 2D sketch.
Because it is compatible with many file formats and is a variant.
JPG, BMP, PNG, DXF, PDF, SVG, DWG and much more. I used illustrator to draw a clock screen.
I used image trace, expand, and ungroup to work on images. simple
I put the heart and the name of CPR band which is my final project on the clock screen.
I think it is simple but good design.
Heart design was done by my colleagues for me.

I used my illustrator to create my final project symbol.

Learn more from 'Youtube' and Adobe help.
I wanted to take a look at each one of youtube, but I had to listen to a few things in terms of time.
So, as time goes on, I plan to do the rest of the lectures as well.
It was easy to look and see because it was written in detail in the illust helped.
In the future, I will be looking through the questions here.

Illustrator can also learn through youtube. And you can see the data in the User Guide.

3. learing 3D design: Fusion360, Solidworks

The 3D design tools are 'Fusion 360' and 'Solidworks'. Fusion360 is good software from Autodesk.
It is available to students and teachers for three years free of charge.
And the program is not heavy and has various functions. 2D, 3D, Rendering, Assemble, Animation, Simulation, and Cam.
Parametric design is also possible. This also learned through youtube. My teacher is youtube!! ha ha ha ha.
I practiced 3D modeling around things. It is too strange and wonderful to be able to digitize what I see in 3D.
Many things are possible in 3D, so it is already a surprise.
I've drawn a lot of things, and I uploaded a funny picture of the hand Spinner.
It seems to be an advantage to the modeling tool that I can easily make it with the `circular pattern` function,
which I thought was 'how to draw it' or 'it is difficult to draw'. So I tried to simplify the rendering.
But rendering has not been used much yet. It is useful when building a house or making a variety of things.
But in my case I am interested in the mechanical hardware part. So I did not invest much time in rendering.

I made a hand spinner with fusion360. I've done the rendering and it works well. And it is a specification that works with a laptop.

parametric design

My understanding of parametric design is that it is easy to enter complex mathematical expressions among many functions and make them geometry,
and when it is necessary to modify it, it is very fast and accurate.
So I've done a parametric design with Fusion 360, but it seems to be possible to quickly fix it later by entering dimensions for each location.
However, it seems to be a design method in which we have to worry about which part should be the same size, or whether to do it all individually.
I think it is a tool to learn more usefully in the future.
And creating a mesh of complex geometric patterns through mathematical calculations is likely to be a fun and interesting design.

Parametic design is a powerful tool. But it is difficult to utilize. You can study through youtube.

Being able to use solidworks for free is a charm of Fab Academy !! hahahaha
Solidworks is a very popular program in mechanical systems but It is expensive ...
Because it has a lot of very specialized functions. So I will use it a lot until the expiration date is over.
I don`t know if it will be available later ... So I designed my final project, the CPRband, with solidworks.
I have designed the watch body, straps, and parts so that they can fit in.
I visualized several parts assemble in one file. Until now, I have designed an external design.
I will go ahead with the design so that the parts can actually fit in.
I am looking forward to seeing which design CPRband will come out.

I got a SolidWorks license and tried to run it. However, it was a bit difficult to work on a laptop.

And I designed the final project, the clock.

I modeled the parts for use with solidworks.
I made it to see exactly what size I could make by making the necessary parts one by one with the correct dimensions.
I designed of charge module, Nano, acceleration sensor, heart rate sensor, Bluetooth, PCB, battery.

And I have painted the actual size of the parts, such as the Arduino, sensors, etc., which are going into the final project.

Thank you!!
