comuter-aided-design

    the assignments focus on model vestor, raster, 2D, 3D, raster animate and simulation raster data consist of pixels. each pixel has an associate value. in another words it is matrix of cells organized in columns and rows, each cell contains some amount of informations
    where as vector data uses sequential points or vertices to represent data. each vertex contains x coordinates and y coordinates

    2d software


    photoshop (raster)
    photoshop it is good raster software, which can help to control image color grading, brightness, contrast, even changing image background
    opening photoshop software


    photoshop main layout, on tabs it is where we find features in photoshop, save, effects, maning plugins
    on workpplace it is a part where an image you are editing is placed
    tools, this section has all the tools we need to edit anything valid, composed with selection tools, cutting tools, moving tools
    painting tools, brushes, text, colors and shpe and many others


    starting with photoshop, locate file tab button choose open, and locate to the file




    i started with changing image background, and controlling colors hue, saturation and brightness, after selecting image using selection tool
    used refine edge tools help to change image backround. resulting this
    to change background image i selected quick selection tool i traced the edge of the image, on the top side of the software
    i choose the >>refine edge and selected to "view" then empty background all selected image details remains unchanged and the background is automatically removed
    on the bottom choose to output file then selected new layer and ok.


    and then changing color properties


    and the results follows before and after


    after playing with this color controlling and bright contols tried bit new feature
    text feature. created new document file with size of A4 ladscape standard paper
    new file has written text "fabacadem" then added new texte with different font style






    with this different text tried to make edit with each text with differnet style
    the first is to change font color and style, give it text shadow this feature is from layer style, the second is changing font style and only font color
    the third text changes the font style and background of image inside to make this we first change from text format to normal structure (rasterize) layer






    GIMP(raster)
    GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program
    for such tasks as photo retouching, image composition and image authoring more about GIMP here GIMP software is similar to photoshop but not likely.
    for the first time i have decided to cut te background and to changed it to white which was not easy as photoshop
    depending on selecting tools from GIMP, photoshop has about 5 selecting tools where this GIMP has about 3 selecting tools






    as it seems in the picture i was not able to detect egde of the picture precisely due to the selecting tool



    inkscape (vector)
    Inkscape is professional quality vector graphics software which runs on Linux, Mac OS X and Windows desktop computers.
    this software helps to design and edit image vector. more about inkscape click here and download the file.
    the layout of inkscape includes the the different tools as it looks like in the image below

    the first trial was to make the color vector of my image then the trying with bitmap trace different 8 colors


    and the second was to make the color vector in black and white


    tried another different tool where i've making a riddle picture. this feature is where
    picture is cutted into many parts and user try to join the right matching pieces


    we start making lines as footprint slice, select an image layer on tabs choose path>>pattern>>object to pattern
    after making an image as path object, then choose drawn lines layer place it on the top of the image after all select all objects
    then to the tabs head in tabs choose path >>division


    after the drawn lines are finnished we select all objects and then under path tools choose division
    i splited the image to be clear with what was going on.

    3d software


    solidworks

     solidworks is 3d modeling software that is used to design 3d objects, modeling, and assembly between though objects i have decided to use the same software which is better and powerful.
    for the first time to use the software. we need to install the software which was the first thing to do.
    after long process of installation and unexpected failures then solidworks opened


    opened and created new document chose new part that is including a sketch and 3d object designed
    starting choosing new plane to work on then head to sketch new drawing this drawing is the base of built objects


    with the help of drwawing sketch i tried new feature called extrude boss/base this feature build 3d object depending on 2d pre drawn sketch footprint
    resulting like this.






    next i came with new idea where it requires new feature from solidworks, as always starting with new sketch


    extrude from drawn sketch


    from the center of cicle on the drawn object i have drawn the curved line perpendiculally


    this introduced new feature similar to the feature mentioned above (extrude boss/base) but this new (sweep boss/base) extrude following the path line given
    resulted like this.


    from the end of this hollow tube i have drawn new sketch similar to the first one i have drawn before and extrude new object.






    freeCad
    FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size.
    Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. for more about freeCad visit here
    like in any 3d design software we start by making sketch as we we did in solidworks. sketch helps to build 3d model depending on 2d sketch footprint.
    for freeCad steps are different from solidworks, from here we start heading to left top corner choose new document after the document is created.
    in the tools choose tool for new body after new body under the created document the under the body create new scetch as follows.


    starting new sketch and make an object from sketched design. after making sketch chosing "pad" tool similar to "extrude" tool in solidworks and the object is built

    after making the sketch and selectig the tool. image follow shows it.
