2.Computer-Aided Design¶
This week I worked on drawing in 2D and 3D my final project idea and started to getting used to the documentation process.
Each week, all in new for me ! the week, i discover the 3D design.
Research¶
First, you have to choose the applications for drawing in 2D and 3D.
by hand¶
Even now, we always need papers and pen, to precise our ideas before to use the PC
2D design¶
I tried to use a 2D tool to design something quite like 3D. I use Coreldraw.
of course, no measure are correct.
When you make a perspective drawing, the main difference between pen and PC, is that when you draw by hand, is the order. By hand, you begin by the foreground to go to the background. With a PC, you become by the background and you cover it layer after layer.
3D design¶
fusion 360¶
design¶
After trying Freecad and coreldraw, i have chosen to use fusion 360 for the 3D design of my project.
And after that, you have learn how to use it. Most of the tuto you can find are about the previous issue.
the beginning.
my first sketch and body
i did this 3D design, which is my actual idea about my project but i did not well :
- i did not use different planes
- i did not creat the sketch at the right place and i did not rename them
- all my 3D bodies were not created at the right place so i had to move them
- i did not use only parametric distance and measure
because of that, my design can not be easily modified, and it’s impossible to add movement.
strategy¶
Because i had not some principles, i had to re-design from scratch.
this new version is not finished and now like that
with all the planes, sketch and bodies named and this parametric measures
parametric design
animation¶
animation¶
pictures and video¶
with paint.net i resized the coreldraw screenshot from 262 KB to 54 KB by changing the resolution from 120 px/inch to 75 px/inch.
how recording the screen with windows 10 : « Windows » et « G » to activate the game bar, but you don’t register the menu.
So i used ApowerREC
the aim of this video is to show the principe of the movement : opening the cover up to the bowl
with https://pdf-convertisseur.fr/, i reduced of 50% the size of the file of the video capture of my screen.
