2(a). The uses of the five types of model
Required Often forgotten
Architectural, structural, process, mechanical and industrial. THESE ARE THE SAME FIVE that requirement 4 offers and requirement 3 makes you choose from, so this is where the choice ahead of you is explained.
Notes and warnings
Note. THESE ARE THE SAME FIVE YOU WILL CHOOSE BETWEEN. Architectural, structural, process, mechanical and industrial are named here as types to explain, and named again in requirement 4 as things to build, and requirement 3 makes you pick one of them. The badge never points that out. Doing this requirement attentively rather than quickly is therefore the cheapest possible preparation for the decision two requirements later, because it is where you learn what each of the five actually is for.
Where this step comes from
- Model Design and Building Merit Badge Requirements (Merit Badge Hub, last modified 2025-12-31), Requirement 2(a) · The requirement names the same five types of model that requirement 4 offers as build options.
