Every reference point, surface, edge, vertex, or point in an unconstrained form has a 3D control that displays when it is selected. Use this control to directly manipulate a form by dragging it along the axes or planes defined by the local or global coordinate systems.
3D controls let you:
You can drag the 3D control arrows to adjust a form to a suitable size or location. The arrows are oriented relative to the selected form, but you can also switch this orientation between a global XYZ, and local, coordinate system by pressing the Spacebar.
