A object movement tool (100) creates an object movement reference frame (26) which has three frame orientation knob handles lying along mutually orthogonal frame handle axes. Provision of the three frame orientation knob handles facilitates use of object movement tool with its object movement reference frame for (1) the positioning, on the screen, a first displayed object (P) relative to selected features (surfaces, edges, or points) on a second displayed object (B), and (2) positioning, on the screen, of a frame center knob handle (220) of the first displayed object (P) with a feature of a second displayed object (B). Another further use of object movement tool is the repositioning of the object movement reference frame itself relative to its associated displayed object. |
