Computer-Aided Design : First Round!

Exploration of 3d and 2d design

Quick reminder of this week assigment :

Learning outcomes:

Evaluate and select 2D and 3D software

Demonstrate and describe processes used in modelling with 2D and 3D software

Have you:

Modelled experimental objects/part of a possible project in 2D and 3D software

Shown how you did it with words/images/screenshots

Included your original design files

What I have done?

The first part was exploring and choosing softwares. There is a lot of choices out there, that was not easy task.
I have tried to divide the softwares in different categories :

Open Source (Inkscape,Gimp...)

closed eco-system (Autodesk, Onshape,...)

In the cloud or local (fusion 360, Rhino,...)

I have spend little time on 2d design for two reasons :

I'm using inkscape and Illustrator already for our laser cutters in the lab

we will have to use it later in other assignments, already next week in fact

I have spend most on my time in fusion 360 in order to tackle 3d design. It's the first time I use this kind of software by myself, quite a challenge!

It's really new for me and I have began with a very easy sketch of a flower vase. I have use a sketch with the spline curve tool and quickly droped the basis of my vase.
I have try after that to scult the vase via extruding, adding edges, t-splines,... for a very poor result.
The resolve tool in the create part of fusion saved my day (thanks Victor!) : it's really quicker for a better result.
I'm using the cloud component of fusion360 to share my project via this link my first projet
Fusion360 is really powerfull to work in team and from anywhere without the need to bring flashdrive and others portable hdd.
As you can see in the image below, you can organise your files in projects with versionning, inviting peoples
Obviously, I decided to move to something to little more ambitious.
Before really diving in the design of my board, I have followed a good tutorial on modeling and sculting in Fusion 360 and designed a basic pc mouse. tutoriel link
I have begun with a simple 3D box that I have pushed and pull along the T-splines, faces and edges to get something who looks like a mouse.

To make the mouse wheel, i have used an ofset plane and drill a hole in the body with another form.
To finish it, I have included a cylinder as wheel, make the filet around it for a smooth effect.
I have also try the "joint" command to make it spin around an axis.
I have also play a little with the texture and rendering


I have also worked in 2D with fusion for my final project, inkscape for the vinyl cutting and Illustrator for some design and my logo. Pictures below!

Summary :
3d modeling is not so complicated once you get your mind around it and begin thinking how objects around us are builded. You can then begin to see each components and start drawing them and put them together
Another important point is to understand how the software you will used is working :
for fusion 360 by example, a sketch is a mandatory beginning for almost everything. It means that you begin in 2d and used that base to jump into a 3d design.
I have choosed Fusion 360 as I have already used Rhino (It's the main tool used in the Lab here) and I wanted to learn something else
