Computer Aided Design

Week Three

Week Objectives:

This week we assignment is all about trying different modelling and design tools to learn new knowledge in design software’s.

The goals this week:

• 1. Model your design of a possible final project using different tools (2D, 3D, vector, raster, animate, simulate and etc)
• 2. Compress image and videos for final project and show them on our websites.

Used Software’s:

• 1. Adobe illustrator
• 2. Krita
• 3. Autodesk Fusion 360

Video editing software:

• 1. Bandicam

2D design:

There are two types of computer graphics with two - dimensions such as:

• 1. 2D Vector: are made up of paths, each with a mathematical formula that tells the path how it is shaped and what color it is bordered with or filled
• 2. 2D Raster: comprised of colored pixels arranged to display an image.

To understand the difference between vector and raster , check the below image and video



Used Software’s:

• 1. Adobe illustrator
• 2. Krita
• 3. Autodesk Fusion 360

Video editing software:

• 1. Bandicam

Krita:

Krita s a free digital painting studio for artists who want to create professional work.

Used by :

• 1. Comic book artists.
• 2. Illustrators.
• 3. Concept artists.
• 4. Matte and texture painters.

As shown below the drawing that i made for landscape by Krita, this an example of raster model .



Adobe illustrator

I try to use Adobe illustrator, I made a wallpaper for my phone and they allow me to use it 7 days for free.

Adobe Illustrator is a vector graphics editor and design program to create images.

home page:



The images below shows the rectangulars that i draw using the toolbar.



i use a tool to subtract top shape to the botton shape of the rectangul

go to window - Path Finder - Shape mode - minus front subtract

I copied the rectangulars and changes the colors of each one of them trying to have a nice design by using a color tool.

The below phone wallpaper that i designed, is an example of vector model.

Autodesk Fusion 360

Fusion 360 is a program helps students, educators and innovators to prepare for the future design. It's an online 3D CAD, CAM, and CAE tool that linking your product development process into one cloud-based platform. It is kind of software thet turn your ideas into reality.

In this software, I try many designs by watching tutorials such as the trolley model then I get use to it so I made my ideas for the final project.

I follow the trolley tutorial in YouTube to help me in designing

I designed a simple trolley as shown below!

The steps are following:

1. Design the Chassis:

I start with the wheelbase, so I draw a line with holes in both side.

Draw the outline.

Draw rectangle and circle in the sketch for the holes and crossmembers.

Then I copy, past and position the chassis parts (frame, crossmember, and, shoulder) All the part are Extrude.

3. Desgin the Wheels:

I make offset from the projected profile.

The I add a circle for the wheel hub.

Extrude the wheel hub and the wheel.

Make and position the two Rings by using Torus Diameter.

Then position the wheel.

copy and paste to create the remaining three wheels.

As shown the car designed :

Model a possible final project:

3D Design of Food Printing Machine:

Design

Mechanical Design

I decide to create 3D Food Printing Machine

z-axis design:

There are four main parts: mechanism of moving along the axis, mechanism of fixing the motor (injection) on the axis, Motor holder to press the injection and the motor that Press the injection

The design look like this:

The first try in design progress

My final desgin looks like that :

The design was made to hold the injection and press in it.

Y-Axis Design:

It design the shield in Y-Axis will the other parts was desgin by my classmates for the group assignment.

The design of Y-Axis design in Fusion360

X-axis Design:

The parts of the design consist of two aluminum profiles.

Two side plastic pieces that fit at one end of each other.

The two plastic pieces connect with two metal rods and a NEMA17 stepper motor in the middle.

My Opinion:

Fusion 360

The best design program I use is Fusion 360 the software has been so easy to use.

The 3D modelling was a wonderful experience I have design many things and see my design in the real life.

Adobe illustrator

Is a magnificent program to create vector-based Illustrations.

Adobe illustrator interface is easy-to-use and understand by user.

Krita

Krita is an excellent image editor.

It is useful for preparing the images and drawing.
