Hello, yes I think you understood me. Basically we already have something familiar, like using a line to adjust background image to the geometry as well as rotate it and scale it. We need the same option in 3D for objects to align into difficult positions perspectively to other objects. A simple two point line that can be drawn from one end of the object(mesh) to the other and then this object can be manipulated using that line, where as one point would move the object, while the other would scale(using the scale tool, or a shortcut), rotate(align really), and align.
