Week_2 assignments

This week need to do two main assignments:

1- To explore as musch CAD software programs as possible and tinker with them.

2- To Model (raster, vector, 2D, 3D, render, animate, simulate, ...) a possible final project.

3- Compress images and videos of the designing process.

4- Post a description with design files on your class page.

So let's beginnnnnnn ^^.

Raster Based Programs:

I started exploring one of the raster based software programs which is Gimp as it is free to download and an open source program.

I followed this toturial to learn Gimp's basics and tools.

I tried to play with the tools a little to make a cool graphity like image/logo (I am not an artist but I am trying to be ^^).

I used free selection tool, brushes, transform, scale and more to make this image out of my selfy to make a logo.

I tried also to make a thumbnail for this week using a mockup you can download it from here.

Here I played more with layers and text and 3D transformation tool

Vector Based Programs:

I love using inkscape as it has a quite welcoming interface and not like other programs.

In inkscape I made a sort of cartoonish logo out of myself using the pen tool and the colour bucket also I made a simple phone holder which had an anime character I love "Killua Zoldyck" from the legendary anime series "Hunter X Hunter". I used trace bitmap tool, alignment and distribution, linked offset and path combineing using boolean operations like uinion and difference.

My cartoonish logo:

3D Modeling:

As for 3D design programs I used 3 programs: Blender, FreeCAD and Autodesk Fusion 360.

Blender

As for what I did in Blender I followed the famous tutorial of the one and only Blender Guru "Blender 4.0 Beginner Donut Tutorial (NEW)".. I designed the donut using a torus object and edited the mesh in Edit mode then opened the sculting mode where I added some details and finally rendered the donut in blender.

I didn't fully mastered the rendering espicialy the lighting settings. Here is my Donut ^^.

I really enjoyed using blender and following this tutorial. I will be using Blender in 3D printing week.

FreeCAD

To be honest I didn't like using FreeCAD its user interface is sooooooo pooor and not inviting but I wanted to try it. I followed a Tutorial to learn the interface and tools and I found that it was the same as a Program I used before called Ondsel. I designed a simple Vase using the revolve method and thickness modifier. and I designed a 3D part using loft and fillets.

The work flow in FreeCAD has to be organized as one starts by designing a part "Part designing" workspace, create a body, creat a sketch using sketcher workspace, leave the sketch and using th pad, revolve and etc tools to convert the 2D sketch into a 3d body.

This is my Vase:

Using loft and fillets:

Autodesk Fusion 360

In Fusion I have done two project one main project and the other was an experimental project using Form design in fusion. I will start by showing first Ms. Spoon which is the experimental project and I think it was great quickly and then divide in details of the main fusion design Chadder "Chair + Ladder".

Ms. Spoon

I used fusion form design workspace which is sort of like the edit mode "Mesh Editing" in blender where you can expand, extrude and shrink faces/edges and so. I followed the tutorial of Kendey "Online product design youtube channels". to explore more about form design. and I made this ^^.

I used emboss to write text on the surface of Ms. Spooon.

Then rendered the spoon in Fusion rendering workspace.

Chadder "The chair which is a ladder and the ladder which is a chair"

In this project I wanted to replicate a product with real life measurement and add some parameters to the design to facilitate the editing process. I wanted this project to be manufactured/fabricated latter on so I added User Defined Parameters in Fusion and these parameters are: Wood thinkness, tab length and offset. And then started my designing process.

My Chadder making steps:

I opened fusion 360 and saved the designed and called it chadder. Then moved to Solid workspace "The default workspace" -> Modify menu -> Change parameters

After adding these parameters. I clicked on create sketch to design the shape of my Chadder frame. And made a fully defined sketch using the parameters I defined and constrains and dimension linkage.

Then I started sketching the frame connectors and the ladder steps.

I extruded the sketched to make components like so:

Then used joint to joint the Chadder pieces

I added all the piece and then hit "a" to open the Apperences menu to add Wood like colour and effect.

I then went to the rendering workspace to render the Chadder:

I animated the Chadder using fusion animation workspace. I used auto explode and auto assemble and some movement key frames to make this animation.

Compressing images and Videos

The a good compression is used to minimize the storage of the images/videos with minimal effect on the quiality.

Images resize and compression

I used this website to deal with image compression and resizing.

For compression all I do is choose the compression option and upload the image and hit compress and the website will do the work.

For resizing I choose the resize option and upload the images but I used the resize by pixels option and keep the ratio of the original one.

Video compression

Here I used Handbrake to compress my videos which is a GUI built upon the ffmpeg commands. In handbrake I edit the following settings: The preset (I usually choose the very fast 720p 30f), check the box of web optimize and go to the audio menu and remove the audio if not needed. Then hit start encode.
