Selecting Elements in 3D
Most basic 3D element manipulations, including moving, scaling, rotating, deleting, and copying, can be done with the Element Selection tool, and are similar to 2D. For example, you can select one or more elements and manipulate them as a single entity.
All 3D modeling tools have a unified workflow that covers the way you select items for creation and modification and how you can modify them interactively.
Selecting Edges and Faces of Solids and Surfaces for Modification
Typically, selecting edges, faces, or vertices, for solids and surfaces is as follows:
