Week 3 : Computer-Aided Design



ASSIGNMENT

  • Model (raster, vector, 2D, 3D, render, animate, simulate, ...) a possible final project, and post it on your class page

    2D and 3D modelling

    The different softwares for 2D and 3D design.

    2D design

  • Raster : Gimp, Photoshop.
  • Vector : Inkscape, Autocad , Free CAD.
  • 3D Design

  • Sketchup, Autocad, Rhino, FreeCad, Solidworks, Onshape, Fusion360, Blender , Inventor.
  • Brief

    As the new week started i got lot of issues with my laptop as it was an old one and many softwares werent working, so i took my sisters laptop but still it was going way behind my schedule and many of the screenshots were on the old laptop. But i did pretty not bad at last, i managed to go through some softwares and i have done my tutorials in 3D Modelling. I've started with GIMP and edited a man in the wheelchair raster image. Then i tried Inkscape and mainly i traced the bitmap of few raster images to make them vector and exportable to modelling softwares. For the 2D and 3D modelling i first tried AutoCad and refreshed all the basic tools and elements in it. Then i took solidworks, which i am a beginner in, so ive learned some tutorials and tried some beginner drawings.

    GIMP

    Gimp(click)

    Gimp is a free and open source raster graphics editor used for editing and retouching images. I selected Gimp as my raster software because i was already familior with Photoshop and it was an oppurtunity to learn a new one. Gimp is absolutely simpler with lighter tools than photoshop, i found it to be much user friendly, in the meantime it is pretty much a pro in editing images.

    Inkscape(click)

    Inkscape is a free and open-source vector graphics editor; it can be used to create or edit vector graphics such as illustrations, diagrams, line arts, charts, logos and complex paintings. I just scrabbled with Inkscape and made some weird drawing while using many tools in Inkscape. Then i toook a proffesor X image from google and traced its bitmap to create a vector file.

    AutoCad(click)

    Gimp

    AutoCAD is a commercial computer-aided design and drafting software application. Developed and marketed by Autodesk. I was familiar with Autocad from my College Days, so i just refreshed certain tools.

    Solidworks(click)

    solidworks 1

    Solidworks is another computer-aided design (CAD) and computer-aided engineering (CAE) computer program that runs on Microsoft Windows. It is widely used by many Engineers for making their designs.I am completely new to this software and i have started learning from the tutorials and online videos.

    beginning

    For the time being I tried drawing, dimensioning and extruding simpler solid bodies. In the below one, i extruded a cuboid from a rectangle and then drafted it inwards from the mid point: see below.

    In this one, i tried extruding to both directions and then drafted one of the extrution inwards.

    I have made another cuboid and then extruded a boss from the centre, see below.

    Then i tried another drawing and made a hole inside the cuboid and then tried fillets.

    I tried one more drawing.

    Autodesk Fusion 360 (click)

    I watched some tutorials of Fusion 360 in youtube and decided to design something myself

    fusion

    I designed a Conduit box with two closed pipe holders

    View the 3D model below

    Please see above gif showing How i designed the conduit

    Pen Holder

    I designed a pen holder for kids with special needs. It is the one the kids could hold the pen with their fingers
