2. Click the drag handle and move the pointer to the new position. The drag handle appears as a black square containing a white circle, as shown in the next figure:
3. Move the pointer over the reference geometry. The reference geometry is highlighted.
4. Release the mouse button. The reference geometry is selected. The handle is snapped and appears as a white square containing a black circle, as shown in the next figure:
To Unsnap a Handle
1. Press SHIFT and move the pointer over the snapped handle. The reference geometry is highlighted and the drag handle appears as a black square containing a white circle, as shown in the following figure:
