Selecting
You can select vertices, edges, planes, axes, faces, surfaces, rounds, bodies, solids, and components in 3D. In 2D, you can select points and lines. You can also select circle and ellipse centers, the midpoints of lines and edges, and the internal points and end points of splines.
You can select components and other objects in the design tree and use the Power Selection to select objects in the same part that are similar or related to the object currently selected.
Objects that cannot be selected are dimmed in the Design window.
