Day 9: (Wed Sep 30, Week 5) Multi-Part Assemblies in CAD

Notes for 2020-09-30.

New Assignments

1. New assignment, due in about five days: part 2 of Exercise: Marble Run in Fusion 360.

2. Preparation for next class: watch Day 10 videos. The three videos total 74 minutes, but I have indexed them both in the video descriptions and in the Fusion 360 lecture catalog.

Daily Agenda

1. Administrative:

   1. Who has received or picked up their kit in the last week?

2. Q&A

3. Breakouts: blind assembly description

   1. each take a minute or two to gather a few small items from your location

   2. then in turns:

      • Show your items to your partner.

      • Your partner will silently decide on a collage or concretion.

      • Dictate a description of the concretion to your partner using the language of joint constraints.

      • Attempt to manipulate the parts into a form using only the verbal description.

      • If possible, take a photo of the result to share.

   3. In Fusion 360, a rigid joint between two parts is identified by a point on a face on each part, with the possible addition of a rotational offset. If your parts do not have flat faces, you will need to decide how best to describe a point on each boundary and observe the perpendicular axis at that point.

   4. Clarification questions are allowed.

   5. Please keep the description to geometric entities and constraints only, not human language description.

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