1) Introduction

The goal is sketch the final project using 2D and 3D software and compress images and videos

3) 2D Software

Step left image

1. Manufacturing & Engineering

  • AutoCAD / AutoCAD LT: product design, 2D precision
  • SolidEdge (2D Drafting): professional-grade 2D drafting tool for free. Mechanical parts and product schematics
  • DraftSight: Works with .dwg files. Engineering teams
  • LibreCAD: Open-source. Simple 2D technical drawings

2. Visual Mockups & Concept Design

  • Vector Graphics: packaging, labels, or flat icons
  • Affinity Designer 2: isometric grids (which make 2D look 3D)
  • Adobe Illustrator: branding and packaging. Wrap 2D designs onto photos of 3D products
  • Figma: websites, flat products

3) 3D Software

Step left image

1. Manufacturing & Engineering

  • SolidWorks:for mechanical engineering and has a robust simulation tools for professional engineers
  • Autodesk Fusion (formerly Fusion 360): versatile tool: cloud, CAD (Design) with CAM (Manufacturing) and CAE (Testing)
  • Shapr3d: intuitive tool and produces professional-grade files
  • Onshape: CAD platform, works remotely across different operating systems

2. Visual Mockups & Concept Design

  • Rhino 8 + Grasshopper: complex products, organic shapes. Grasshopper allows parametric design, creating patterns.
  • Blender: CAD model, realistic shot
  • KeyShot: industrial designers, materials (metal, plastic, glass) and render

4) Project sketch

Define the 3D software

  • Download and install Rhinoceros
  • Step right image

    Modelling the camera

  • 3D Camera modelling
  • Views: front, superior, right, perspective

    5) Image and video compression

    a) Image


    • A lot of tools
    • We used ILoveIMG, TinyJPG
    • One option is save with other format

    6) Final results

    • Modelled experimental objetcts/parts of a final project in a 2D and 3D software
    • Shown how you do it with words, images and screenshots
    • Documented how you compress your image and videos files
    • Included your original design files
