The task list for this week:
- Model (draw, render, animate, simulate, ...) a possible final project.
- post it on your class page with original 2D and 3D files.
2D Designe
This week I focus on exploring various 2D & 3D design software. Let's see the first 2D design
Raster Vs Vector:
2D image designs are classified into two major categories
- Raster.
- Vector.
![image not found](img/image30.jpg)
Raster: Raster img are made of pixels or tiny dots that use color and tone to produce the image.
Vector: Vector graphics are digital art that is rendered by a computer using a mathematical formula.
In the following table, I covered the difference between vector and raster to know more about it check this blog.

As an engineer, I have a little bit of a good hand on CAD software but I have not explored 2D modeling up till now . Software like gimp, photoshop are known to me but I am going to explore them for the 1st time in my life. 2D designing.
Inkscape:
To start with the 2D design I started learning Inkscape. As it's open source and most of the content is available online.
Here is how I started learning it.
Downloading and installing Inkscape.
![image not found](img/image33.jpg)
It’s very simple to download and install Inkscape. You just have to go to Inkscape.org And select the version based on your OS. As I use Windows, I select the Windows version of Inkscape and download it into my system. I got a .exe file. For installation I just opened it.
Step 2. Exploring the user interface and layout.
Usually, whenever I start exploring any new software for the 1st time I use to read the manual of the software which provides basic information about it.
![image not found](img/image35.jpg)
This is the basic interface of Inkscape I got from their user manual.
Step 3. :Now its time to make some thing using inkscape.So i decide to try one of tool for tracing a bitmap image into a path .for that I fallow this tutorial from Inkscape manule you can find such side tutorials on there side .
Step4:Opening the application and Import a Image for tracing a bitmap image into a path. I use the same illustration image of me for this activity.
![image not found](img/image11.jpg)
![image not found](img/image25.jpg)
Step5:Then I select the path from the menu bar in path select trace bitmap option .update it for selected Image.
![image not found](img/image22.jpg)
![image not found](img/image32.jpg)
Step6:Its show the preview of the trace bitmap generated .Then apply the operation for the selected image by clicking on apply option.It will automatically generate a teace bitmap.

Step7:Then I fine adjusted the design using path tool editor and I used setstroke to map the boundry of design.
![image not found](img/image18.jpg)
![image not found](img/image19.jpg)
Step8:After maping the boundry of image I use Creat and edit text object tool to wright name below the edited path.
![image not found](img/image17.jpg)
![image not found](img/image37.jpg)
Step9:After this I added a boundry box to the design using the box option and coloured it like shown in the image using spray option .

GIMP:
I use gimp for dearkening the fent lines on my sketch using brightness controller tool.
![image not found](img/image29.jpg)
![image not found](img/image12.jpg)
I also tyr Bim plugin in Gimp for compressing img.
3D Designe:
Fusion 360:
I need a connection element design for my burner So i tried to design one in Fusion 360.
![image not found](img/image7.jpg)
1.Start with sketch mode Drawing some circles:
![image not found](img/image39.jpg)
.
2.Defining dimensions for circles and there distance from each other :
![image not found](img/image9.png)
.
3. Using tangent constraint:
![image not found](img/image5.jpg)
.
4.Detected Off set which can be a problem for Design.
![image not found](img/image27.jpg)
.
5.Use Concentric constraint for making circle center allina.
![image not found](img/image15.jpg)
.
6.Convert construction line to object line :
![image not found](img/image4.jpg)
.
7.Use Trim tool to remove excess lines and curves in design:
![image not found](img/image13.jpg)
.
8.Use Extruded tool to generate body:
![image not found](img/image40.jpg)
.
9.Select body surface and sketch circle on it:
![image not found](img/image3.jpg)
.
10.Cut the body using Extruded tool:
![image not found](img/image38.jpg)
.
11.Use Chamfer tool for creating chamfer:
![image not found](img/image23.jpg)
.
12.generating body on body by extrugion.
![image not found](img/image6.jpg)
.
13.Final Design:

.
Solid works:
I also try to design a servo motor in solid works. As I am going to use on in my final project for controlling the gas flow towards the burner.
1. I use solid works part design to Design the servo motor parts as follows.
![image not found](week2/servo body/W2-select part 1.jpg)
.
2. I first draw the suitable sketch and make it 3D using the Extrude command as you can see.
![image not found](week2/servo body/W2-skech and extrude 2.jpg)
.
3. Then I reuse the sketch command to Draw the sketch to attach nuts and bolts on the servo motor I also use various sketch commands this time like offset, line, construction line, circle, sketch fillet, etc.
![image not found](week2/servo body/W2-off set 3.jpg)
.
4. I use the sketch mirror command to mirror the sketch items I draw and where I where symmetrical sketch parts.
![image not found](week2/servo body/W2-mirror 4.jpg)
.
5. After that I redraw the sketch portion on the top of the servo motor using the circle command and use dimension command to give it dimensions.
![image not found](week2/servo body/W2-skech and dimension 5.jpg)
.
6. Then I use the chamfer command to chamfer the bottom edges of the servo motor body. I also use the fillet command to make sharp edges smooth.
![image not found](week2/servo body/W2-chamfer 1.jpg)
.
7. I also draw bolts using the sketch command and then extrude them to make 3D.
![image not found](week2/servo body/w2-screw skech 6.jpg)
.
Then I use excrude command to make them 3D and chamfer it to give them bolt like shape.
![image not found](week2/servo body/w2-making nut and bolt excrude.jpg)
.
8. Then I again use extrude command to make a bottom output for the wiring of the servo motor.
![image not found](week2/servo body/w2-excrude 2 teper 7.jpg)
.
9. Lastly I make a hole using cut-extrude to fold a shaft.
![image not found](week2/servo body/W2-cut 8.jpg)
.
10.finally, I give the appearance to the servo body by assigning the material and colour.
![image not found](week2/servo body/W2- apperiance and matterial 9.jpg)
.
As I make the servo body. Similarly, I make other components I need to complete my servo motor.
Servo other components.
1. Servo Horn Sketch.
![image not found](week2/servo other part/W2-servo horn skh.jpg)
.
2. Exclude the sketch to make it 3D.
![image not found](week2/servo other part/W2-horn complet.jpg)
.
3. Similarly I draw the sketch of the shaft and then use Exclude command to make it 3D.
![image not found](week2/servo other part/W2-shaft apperiance.jpg)
.
Assembly:
1. I use solid works part assembly to assemble the various servo motor parts as follows.
![image not found](week2/assembly/W2-assembly windo_1.jpg)
.
2. I use different types of mat commands to assemble the parts such as coincident, concentric, Lock etc.
![image not found](week2/assembly/W2-shaft lock.jpg)
.
3. This is what the final Assembly look like.
![image not found](week2/assembly/W2-final assembly.jpg)
.
Animation:
For animating the servo motor I use SOLIDWORKS Add-In where I found the SOLIDWORKS Motion feature to animate the servo motor horn motion. Its window looks life follows.
![image not found](week2/Animation/w2-Animation Servo 2.jpg)
.
I modify the motion to oscillatory motion and frequency to1 Hz and rotate the motor at 180 degrees. and set the timeline to 14 sec.
![image not found](week2/Animation/w2-animation selext motor 1.jpg)
.
This is the video during the animation as you can see.
This is the final Animation video I served.
Rendering:
Photo View 360:
For rendering in solid works I use photo view 360 Initially . But I don't like it . I try some Initial rendering work Edite the image quality and type as you can see in the picture.
![image not found](week2/rendering/rendering view.jpg)
.
After that, I move to the SOLID WORKS Visualize.
![image not found](week2/rendering/render.jpg)
.
I assign the material and colour appearance to Its as you can see in the below image.

This is what the final rendered Image looks like.
