Dragging Components from the Graphics Area To add components by dragging from the graphics area: Ctrl + drag the component from the graphics area of the source window into the graphics area of the assembly window, but do not drop it immediately. Use one of the following entities to drag the component: a linear or circular edge, a temporary axis, a vertex, a planar face, or a cylindrical/conical face. You can inference the assembly origin. You can also Ctrl + drag a component from a subassembly. When the pointer is over an entity of another component that is a potential mate partner, the pointer changes to indicate the mate or mates that will result if the component is dropped at this location. A preview of the component snaps into place. Drop the component.The mates are added automatically.
