Day 8: (Mon Sep 28, Week 5) Parametric CAD

Notes for 2020-09-28.

Notes from Day 7

Most students succeeded at getting Fusion 360 file sharing set up, but there are a few glitches still to resolve. Current notes are at Fusion 360 Team Protocols.

New Assignments

  1. New assignment, due in about two days: part 1 of Exercise: Marble Run in Fusion 360. (Part 2 will be released soon.)

  2. Preparation for next class: watch Day 9 videos.

Daily Agenda

  1. Administrative. Updated and new:

  2. Q&A: CAD vocabulary review

  3. Breakouts: blind CAD drawing

    1. each take a minute or two individually to sketch out a flat part with a few features on paper

    2. then in turns:

      • Dictate a description of the part to your partner using the language of sketch constraints.

      • Attempt to draw the part using only the verbal description.

    3. Clarification questions are allowed, but no peeking at the picture.

    4. Please keep the description to geometric entities and constraints only. E.g. the CAD system wouldn’t understand you if you said “draw a smiley face”, but it might have a chance if you said “25 mm circle centered on the origin, 5 mm diameter circle at (-5, 5) mm, equal circle symmetric across Y axis, etc.”

  4. After class: office hour time continues for a while.
