3. Computer Aided design¶
OBJECTIVE¶
Model (raster, vector, 2D, 3D, render, animate, simulate, …) a possible final project, compress your images and videos, and post it on your class page
Actually this is chalanged to me to learn this software so when We discussed with our instructor and they have arranged session solid wokrs and freeCAD. We have also experienced to work on 3D Designing software like freecad , Tinker cad.
Brief introduction of CAD software.¶
What is CAD Design i.e. Computer Aided Design ? Basically CAD (computer Aided Design) software is used for to design the documents products designing. Generally to draw the Engineering sketch like graphical symbols line, various plane and shapes also means its gives the detail information of any component in graphical form.CAD is basically gives the preliminary design and layouts, design details and calculations, creating 3-D models, creating and releasing drawings, as well as interfacing with analysis, marketing, manufacturing, and end-user personnel. CAD software enables
Various Types of CAD Designing Software and tools¶
1) Raster 2D design¶
2) Vector 2D Design¶
3) 3D Design¶
What is raster 2D Design¶
A raster graphic basically is made up of a collection of microscopic sized pixels, which are arranged in a two-dimensional grid made up of columns and rows. The number of bits stored in each pixel is known as the color depth. The number of pixels, called resolution, affects how much detail can be depicted in an image.So when I started to learn above software for the week 2 assignment first i have experience to work in paint only for editing images and changed the size of any image in pixel (wikipidia).I have little heart about software like paint, Photoshop,krita, Gimp but initially I don’t any experience to work on this kind of softwares so i started to learn this software from basic concepts.
1) GIMP Software¶
Initially I have referred the GIMP Tutorial before work on it Gimp Tutorial To manipulation of image.
First I started to work on Gimp basically it is GNU image manipulation program. It is used to photo retouching, image compression, and image authoring. In first step to learn this software I have to install this software in my laptop. I have searched in Google Download GIMP free this type of window will open and then first I have down loaded this and installed it.
After that I have started work on that first I edited my own picture here for that I have to go for file menu and by dropdown it open file where my image is stored in my laptop so this kind of window may appear on my screen. After that I started editing means I have experience that we can resize the image, change the pixel size or we can also change the color of images
So after doing some kind of operation I experience that image color and size we can edit in this gimp application.
After editing my image looks like below picture. We can do such many operation on any image which we have stored in your laptop files so this kind of things we have been taught in one of the member Miss joyeuse work in FABLAB-RWANDA
If i put on any browser Shotcuts keys to oprate Gimp i will get all opertaions which we can done with Gimp software
Using GIMP Software i experinced first if we want to reduce the size of image in pixel so it can be done easily by follong below steps
1) With GIMP open, go to File > Open and select an image.¶
2) Go to Image > Scale Image.¶
3) A Scale Image dialog box will appear like the one pictured below.¶
4) Enter new Image Size and Resolution values¶
3) Select Interpolation method.¶
4) Click the “Scale” button to accept the changes.¶
Its quite difficut when i have experinced it but finally i was able to reduce the size of any image in gimp The size of my image before editing is 102.4kb
After that this kind of window will appear on my screen
After that this kind of window will appear on my screen
After editing the image reduce to 64.1kb
We can reduce the size of photo in Gimp software file reducing the pixel and save this file in JPEG format so it can be reduce in pixels that I have also experience
I Have used GIMP and BIMP for image reduction,The image size used to increase as I am not able to define the format to which the image is to be exported. it used to save in PNG Format
One of the interesting fact is that while working on raster designing that I have experinced that if you want to change the background of any image so go to remove.bg by cliking on this site so you can put any kind of background to your image I have experience this while learning Raster Design.
I have to upload my image by clicking the upload image tab and select my image from stored files its looks like this.
In this way I can change my image background by using this interesting tools called as remove.bg
2) Vector 2D Design¶
vector¶
it was the first time to use inkscap software .fisrt i downloaded it from this link here
What is basically the vector 2D Design? It is defined in terms of 2D points, which are connected by lines and curves to form polygons and other shapes. Each point has a defined position on x axis and y axis of the work plane.Coreldraw, Inkscape,FreeCAD such software is used for vector 2D design. so for this assignment i have tried to all this operation in vector Design software
Inkscape Software:-¶
When I started leaning the Inkscape software gone through the link Inkscape Tutorial It is a professional vector graphics editor. Inkscape is free and open source software. It is generally used for logos, diagrams,maps and web graphics.then i started to download inkscape
2D DESIGN¶
Open inkscape¶
setting document properties
Go to the object on toolbar find distribution alignment
align the object the area where you want to place it before distribution i selected stars and circle with create spiral
select circle
select stars and go to the distution alignment
go to alignment all stars depending on what you want to make defferent
go to the path on toolbar make `difference
`
go to the path on toolbar make difference
go to the path on toolbar make differenceto all objects placed on main object we want to make the defference
during cutting using laser cutting machine available in my lab
final result of my design
3D Design¶
What is the solidworks¶
solidworks is a cloud-based 3D modeling, CAD, CAM, CAE, and PCB software
platform for product design and manufacturing. Design and engineer products to
ensure aesthetics, form, fit, and function. … Directly edit existing features
or model fixtures with the only truly integrated CAD + CAM software tool.
installing solidworks
· Step1:solid works
· Step:Click the Download now
· Download solidworks free · Youtube Link :DOWNLOADED HERE
solidworks :
· Step1 : i installed the solidworks in my computer.
· Step 2: i started to use the software and redesign different things
open skech of the solidworks select the plane
i selected the plane and using smart dimension to mesure my cube size is 120 mmm by side
in my project of cubesat i designed the cube using solidworks
select the centered line and line and drow following the shap of the bullet of front view
i make the measurement on the line of bullet shap i designed
go to the smart dimension and select each measurement
select the selected contours and sketch region
The final design of the bullet
