The QD Object Control is a dockable dialog box that allows the user to create groups of drawing objects and toggle them on or off or isolating them no matter what layer the objects are on. If you are working with a large complex drawing this utility will be a great help in 2D or 3D. The QD Object Control really shines in 3D, you can take an assembly of objects and hide then just to get then out of your way or use the highlight function to get a quick selection of the assembly for copying or moving or any other AutoCAD function.
