### About this course

This training takes you through two body fields and two applications of this advanced field driven design concept. After completing this training, you will have developed an understanding of what occurs when you add, subtract, and divide two bodies.

**Prerequisites:** [101: nTop Essentials](/lessons/ntop-essentials/overview), [210: Intro to Lattices](/lessons/intro-to-lattices/overview), [220: Intro to Field Driven Design](/lessons/intro-to-field-driven-design/overview), [321: Intermediate Field Driven Design](/lessons/intermediate-field-driven-design/before-we-begin-intermediate-field-driven-design)

**What is covered:**

* The process for creating the two-body field.
* How to apply the two-body field to ramp a lattice structure.
* How to create conformal ribbing defined by two bodies.
