You will organize components, place parts, apply relationships, check alignment, and create exploded views.
IED Unit 3
CAD Assemblies, Prototyping & Technical Drawings
Unit mission: Build a full rocket CAD assembly, check fit and alignment, prepare parts for printing, assemble a physical prototype, and communicate the final design package.
Unit Overview
What Unit 3 Builds
You will move from part modeling into assembly relationships, prototype fit evidence, and professional technical drawings.
You will export, slice, print, assemble, fit-test, and revise a physical rocket prototype.
You will create drawing sheets with views, parts lists, balloons, notes, and revision evidence for presentation.
