Copy of 04.10 Red Static Tolerances
Learning Objective: YWBAT dimension, sketch, and model an object that fits over another object.
Essential Question: How do fit tolerances affect our design process?
Do Now (2 min): Read and answer in your notes.
Unit 4: Design from Images
Yesterday I spoke with a student who asked, "Why do we have to make a lid? What's the point in doing that?"
We're getting to the point now where we're (finally!) focusing less on how to use 3D modeling software and shifting our focus to using that software to design things that we can print.
Do you think that starting by designing a lid might be worthwhile in our goal of learning how to design things that we can use to solve our own problems and fulfill needs in our lives? Why or why not?
Dimensioning & Fit Tolerances
Due Today:
1. Redo your dimensional sketch of your can and capture all measurements.
2. Create a sketch of your lid.
3. Determine the inner and outer diameters of your lid. Be sure to write the equation showing how you derived each measurement.
4. Resubmit by the end of class. If you finish early, open a new file in Tinkercad and start to model your lid.
The can in the image below is 66mm in diameter. What should the diameter of the outside of our lid be?
How did you arrive at your answer?
