Toward the completion of a general best-fit operation (Ctr+B), you are provided with a series of options that are not displayed in the single instrument version of the best-fit command. This is not the case if you directly right-click on a particular instrument and select Best-Fit from its locate menu, ad the move operations are pre-defined in that case.
These options are described below.
Move the corresponding group. Determines whether the transform is applied to the corresponding (moving) group. If unchecked, the corresponding group is not moved.
Move Objects. If you’d like to transform other objects, select this option. After clicking OK, you’ll be prompted to pick the additional objects to transform.
Move Instruments. If you’d like to transform instruments, select this option. After clicking OK, you’ll be provided the opportunity to select instruments to transform.
Adjust Instrument Scale Factor. This option is only available when the scale degree of freedom is unlocked during the fit. When checked, the scale factor calculated during the fit opera- tion is applied to the moving instruments.
Move a copy of the working frame. When selected, the working frame will be copied, and the transform will be applied to the copy. This creates a frame that can be used to report the coordinates of the points as they were prior to the transformation.
Create alternate reference frame. When selected, a frame is created that represents the inverse of the applied transformation. This allows you to transform the moving objects back to their position prior to the best-fit operation through the use of a frame to frame transformation.
