Sweep & Loft Solid Geometry Phenomena-Based Lesson: Self-Intersecting Titanium Exhaust Sweep & Corkscrew-Twisted Turbine Blade Loft 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 Sweep & Loft Solid Geometry, built around the phenomenon Self-Intersecting Titanium Exhaust Sweep & Corkscrew-Twisted Turbine Blade Loft. It is sold separately from the other two parts of the set.
