Lesson 5: The CT Tech-Drafting Challenge
Duration of Days: 4
Lesson Objective
Students will produce a complete technical suite (3-view and isometric) from a physical object under timed conditions.
How do you manage your time between measuring and drafting?
What is the "minimum viable information" needed to make this drawing functional for a machinist?
Summative Exam, Precision, Professionalism.
CT CADD.02.03: Demonstrate proficiency in measuring with precision instruments.
CT CADD.09.02: Create a final technical drawing package.
Students are handed a physical mechanical part (e.g., a custom aluminum block or a 3D-printed bracket). They must measure it with calipers and produce a full AutoCAD sheet containing a 3-view orthographic, a 2D isometric, and full dimensioning.
Purpose: To simulate a "real-world" hiring test for a drafting position.
DOK Level: 4.
Extended time for students with IEP/504 accommodations; choice of "Standard" or "Advanced" physical objects.
Unit 4 Final Grade: Evaluated on measurement accuracy, layout alignment, and layer management.
Physical parts, digital calipers, AutoCAD final exam template.
