_About me

Designing is the first step of a manufacturing process .



This class receives very different students, all you with different background. Most might be used to CAD. There are multiple CAD SW as you saw yesterday in class, but for this class, we will focus mainly on detailed model for designs in the order of the meters, with mm details.

1. Introduction to CAD basis

  • All them expell the same files. STEP, STL, DXF.

  • The majority of HTMAA projects could be done in any CAD software, what changes is how much of a headache it will be.

  • The nature of this class operates in the mesoscale (elemens from cm to m). Also, we will cad to the detail. That makes a great need of CADS with a timeline and tree structure

  • 2. Why Fusion 360

  • Great starting point (online tutorials), clean UI

  • CAD, CAE, CAM

  • Free

  • Cloud base

  • If needed, naturally your work will ask for other CAD program (Rhino, Solidworks, Catia)
  • DISCLAIMER : This tutorial is meant to be as universal as possible. Most CAD tools shares similar tools and design strategies, what it change from one to one is the UI.


    3. Hands on. What do we see in a CAD UI.

  • 3D Canvas, axis and views.

  • Options to work with Surfaces, Solids and Construction Elements (very very important)

  • File system management (cloud base, shareable).

  • Up in the tab, Fusion general options to import, export, etc.

  • Timeline

  • 4. Parametric design

  • Sketches

  • Solids

  • Surfaces

  • Drawings

  • 5. Importing and Exporting

  • Internal Importing

  • External Importing, STEP, DXF, STL

  • Exporting STEP, DXF, STL.

  • 6. Design for Manufacturing

  • Design restrictions. Assembly viability, clashes..

  • Consider making Jigs!

  • Design for 3D printing

  • Design for Laser cutter

  • 7. Extra content. APIs

  • Contact me at aprubio [at] mit.edu if you want to have a tiny separated session on Rhino APIs (rhinoscriptsyntax)
