# Overview

> This course will take you through the basics of meshing in nTop used alongside our implicit bodies. We recommend this course, nTop Essentials, as it provides vital recommendations for when you are importing a mesh, creating a surface lattice, running a simulation, or planning to export.  After completing the course, you will understand when and how to mesh in nTop.  You will also gain familiarity with some of the operations and properties of meshes and best practices for working with a mesh.
