
Assembly- when all the parts are put together to create the object/problem.

Exploded View- when all of the parts have been assembled and then “tweaked” so that they are
separated for the annotation process.


Introduction
The purpose of this lesson is to help students build their 3D/parametric modeling skills. When the skill builder
problems are completed, students will begin their own designs and prototypes. However, to get to that stage,
they must know how to do the building steps.
