## Keep one reference while exploring

Use a fixed Inspector reference when you need to compare a known object with
nearby objects or check whether a second object has the same geometry or
properties. The VC selection can change independently until you ask Inspector
to inspect it.

## Steps

1. Select the object you want to use as the reference and open Object
   Inspector.
2. Choose a gadget that answers the investigation question, such as **Object
   bounds** for dimensions and world center.
3. Clear **Follow selection** in the Inspector toolbar.
4. Select another object in the VC layout. The VC selection changes, but the
   Inspector continues to show the held reference.
5. Compare the current VC selection with the values for the held reference.
6. When you are ready to change the reference, select the magnifying-glass
   button beside the refresh control to inspect the current VC selection.

## Return or hand off the reference

* Use the back button to return to an earlier inspected object. The mouse
  back and forward buttons also move through the inspection history.
* Use the select button to make the held inspected object the current VC
  selection when the object is still valid and selectable.
* Use the Notes button to create a note with a reference to the held object
  before continuing the investigation.

## Result

The Inspector and VC selection can represent different objects while follow
mode is cleared. Re-enable **Follow selection** when the panel should track
each later layout selection automatically.
