Extrude & Revolve Solid Features Phenomena-Based Lesson: Injection-Mold Core Seizure from Zero Draft & Fixed-Extent Boss Puncture Presentation | Computer Aided Drafting II | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Phenomena-Based Lesson in the Computer Aided Drafting II (grades 9–12) chapter Extrude & Revolve Solid Features, built around the phenomenon Injection-Mold Core Seizure from Zero Draft & Fixed-Extent Boss Puncture. It is sold separately from the other two parts of the set.
