♦ Computer Aided Design♦

Again click on filter then Blur and select Linear motion blur and change the length and angle.

Select Wrap transform and click on move tool after that create new layer then click on edit and select fill with FG color.

click on filter ,select noise then HSV noise and make Hue-180 and saturation,value to 1.

Go to color select saturation make scale zero then go to filter select blur then gaussian blur and change X and Y to 6.26.
click on colors select levels and adjust input levels.

Again go to filter select blur then linear motion blur and change the value of length then click on colors select curve and adjust the X and Y value.

Click on unified transform tool drag image to middle and the drag it from bottom right and left.

Click on layer ,select image to layer size.After that take second layer upside and first layer below of that then click on
filter select map go to displace and choose aux input as second layer.And you will get water reflected image as shown below.

KRITA

Open krita ,go to file select new file open your image.Select Bezier curve selection tool.Select part which you want to remove.

Use Shift+ctrl+I command to highlight the selected part.

Press B or select brush tool to remove the background

As we can see background is removed from this image.

Comparison between GIMP & Krita

In raster we play with pixel values .If we change pixels it will reflect on our image.
In GIMP we can resize the image,also we can give different effect to image.We can crop image.
GIMP have different filters ,by changing the value we get different effect.
IN GIMP we can resize group of images .For this we have add plugin for batch process.
It is easy to use.Krita is also raster software but this is not more useful as compared to GIMP.
User interface is not good.Both software are open source but I am comfertable with GIMP.

What is Vector?

Vector graphics are not made up of pixels.Vector composed of lines or path that are either straight or curved.
Image can be scaled to large value without losing quality.Image will not get blur.
Bacause of this designs are made using vector software.(wikipedia)

Coreldraw

Click on file select new file .Using outline pen tool draw the shape.
By adjusting the arrow we can change the shape.

Draw the line as shown in figure.

Fill the color using smart fill tool.

Select interactive fill tool and fill the color and adjust the intensity of color by using arrow.

Again select interactive fill tool and fill it with blue color.

Select the image and right click on cross button which is in right corner.That is used to remove outline.

Copy the image

Mirror the image which is copied

Drag the image and change the postion.

Fill the color using interactive fill tool .

Draw the design using pen tool as shown in figure.

Select the drawn image,right click on it select order and then click on to back of page.

Change the color using interactive fill tool.

Select ellipse tool and draw circle.

Make the circle white and place that circle in middle.

This is final output.

Inkscape

Click on file ,select new file.Draw hexagon.

Change the color of hexagon.

Make it duplicate and again change color to pink.

Shift duplicate image upside.

Again duplicate pink hexagon and shift it as shown in figure and make it green.

Select Grey and pink surface click on path and select intersection.

Select both the parts.

Go to path and select intersection.

Delete the grey surface ,click on Snap cusp node.

Apply shift+ctrl+A command and change alignment to left edges.

Change color of all sides.

Group the selected surfaces.

Duplicate the selected image.

Select the image and drag it inside from on corner.

Here is the final image which is showing 3D effect.

Comparison between Coreldraw & Inkscape

It was very good experience of using coreldraw and inkscape.Inkscape is open source and coreldraw is commercial.
We can make logos using coreldraw.Inkscape is easy to use.Commands are easy to understand.
I feel coreldraw is little bit difficult as compared to inkscape.I explored more command using inkscape. Inkscape is free software and coreldraw is commercial thats why I am using inkscape.

3D Design

I have never used any 3D software before. It is very difficult for me to learn this software and make design.
But also I am excited about 3D software.This is an chance to improve my drawing skills.So I started watching tutorial.
In Neil's lecture told about open source software that is FREECAD. I decided to use Freecad and Fusion 360.
I have selected random object and made design of it.Also I have rendered ,simulated and animated the design. Our local instructor Apeksha Ma'am made video tutorial on freecad.I reffered that tutorial also.

In 3D design I have used below two softwares

Fusion 360

Go to file select new file.

Click on create sketch and select the plane which you want.

Go to create click on polygon ,select inscribed polygon. Put value of edges as 12.

Use extrude command and extrude selected part.

To make it in diamond shape change the angle to -45.5 and also distance.Pull that arrow downward.

Again change the angle to -50.5.

Click on appearance icon and select the material like metal ,glass,wood.I have selected wood.

Click on scene setting and select one of the scene.

This is render image using wood material.

This is render image using glass material.Render image looks very nice.

Go to simulation mode and select one of the study type.

Select study material then click on mesh and change the element size.
After that go to load icon select the load.I have applied structural load.

Error occured because of structural load.It can't applied to this material.So I changed the load.

Error get solved by changing the load.Solve it locally.

Showing the status of simulation.

Here are the result details of simulation.

Simulation is very effective because it is also showing minimum safety factor.

Here we can see the graph.It is also showing diffrent factors and its effects.

When we applied stress it will look like image.

When we applied displacement ,minimum and maximum value also get changed.

Here I applied reaction force.

Here I applied strain. All parameters have different value.From simulation we can understand weak and strong part of our design.

♦Animation♦

Go to animation and change the position of object.Rotate the object,give angle to it.

Here is the animation video

By creating account on sketchfab I have made another video.For that I have saved fusion 360 file in STL format.
After that I uploaded that file in sketchfab.As we rotate the mouse video will rotate as per that direction.

Freecad

Click on file select new file.Go to sketcher mode ,select XY plane.

Draw the rectangle as per your dimension.

Select right corner point and lock it.Set the dimension of rectangle and also for lock point.

From sketcher mode go to part design.

Create body and select design.

Change the pad parameter and use Pad command.

So this is simple box.

Again go to sketcher mode and draw shape as shown in image.

This is complete casing box with hole.

This is lead of box.After assembly both part will fit correctly.

Comparison Fusion 360 & Freecad

Both softwares are new for me.I started working on freecad first.I used extrude command.I made small object in freecad.
User interface is not good in freecad.But freecad is open source software.Fusion 360 is cloud based online software.
User interface is very easy. In fusion 360 we can do rendering,animation,simulation very easily.
I will use fusion 360 for my project design part.

Project part covered:

For my project I made casing in fusion 360 and I will cut it using laser cutter.Also I required casing for ultrasonic sensor,for that I have made design in fusion 360.

This design is made for sensor .I will 3D print this design .For 3D printing I required .Stl file.So I have saved .Stl file.

I have given all design files in downlodable format.

Learning Outcomes:

As electronics engineer ,I never used any CAD software.This week was very excited and interesting for me.
I learned about raster ,vector and 3D design.In 2D design I understood lot of new things like how to draw,how to change color.
In raster I learned how to resize image,how to gove different effects.In 3D design I made small object using pocket,extrude commands.Also I have done rendering,animation,simulation.I like rendering in 3D software.
