3. Computer Aided design¶
This week I worked on modeling on 2D and 3D my possible final project.
Modeling on 2D¶
To make the first computer design of my possible final project, I used the free software Inkscape. This software allows vectorise raster images in a very simple way.
Inkscape also features drawing tools that allow you to create various shapes, much like programs such as Corel Draw or Adobe Illustrator.
The reasons why I decided to learn more about this software are as follows: It is a free access software which allows me to use it on any computer and not only on my personal computer. It has useful and easy to use tools.
When I was testing flower movement mechanisms, I made new design drafts and realised that I needed to design such opening and closing mechanism.
Modeling on 3D¶
Before using the 2D and 3D design program Autocad to design the opening and closing mechanism, I downloaded the 2D drawings of the Worms and Worm Gears from the website Mcmaster-Carr
With the 2D drawings and measurements I started to design ths gears support.
As Autocad is alsos a powerfull 3D software, I started de 3D design.
The most used commands to build my 3D were:
- Extrude
- Slice
- Presspull
Despite the many programs that have emerged, Autocad is still a versatile and very useful tool for the construction of two and three-dimensional models.
From the same Mcmasterd web page I could download the 3D Worms and Worm Gears models.
I have used for the first time the Fusion360 software. It is a powerfull tool. I started spliting bodies.
Then I learnt how tin create a 2D sketch
And finally, I modified the gear with a boolean operation.
I will definitely start learning Fusio 360 in a deep way.
