Lesson Objective

Students will produce a complete, 3-view orthographic drawing of a complex object with 100% alignment accuracy.

How do we check our own work for precision?

Does this drawing provide enough information to build the part?

Self-Correction, Technical Audit, Dimensional Consistency.

CT CADD.03.03: Demonstrate the ability to draw orthographic views.

Students are given a complex 3D isometric "Master Object." They must create a formal 3-view drawing on a bordered sheet with a title block.

Purpose: Final assessment of hand-drafting logic before moving to Isometrics.

DOK Level: 4 (Extended Thinking).

Students can choose between a "Standard" object or a "Challenge" object for the final grade.

The "Missing View Challenge" Exam (Summative).

 

Drafting boards, final "Master Object" isometric prompts.
