Editing Objects in Construction History
You can edit child and parent objects in the construction history.
To edit a current child object, double-click it in the Model Browser. In your
scene, the object is displayed with a Control Panel. You can modify the object
directly or change its parameters in the Control Panel.


To edit a source or parent object, select the Round object, then from the
construction tree, double-click the grayed-out Cube object.
