The Edit Graphics (Meshes) component tab contains tools for editing separate parts of components (meshes), as well as entire components. These tools let you take full control of the editing process.
Open the Properties to set your preferences for working with Edit Graphics:
The Mesh dialog provides you with a list of all the meshes that a component is made up of, which can make it easier to find a certain mesh.
Learn more about working in the Mesh dialog in this article.
There are two buttons for selecting meshes; Single mesh select which selects an individual mesh, and Component meshes select which selects entire components as a group.
