Adjusting a stacked object
Change a live stack relationship without confusing it with editing or merging the source objects.
Select the linked object to adjust the settings offered by its stack relationship. Surface Offset, placement and orientation affect how the object meets its target. These controls are not a universal set of blend sliders: different stack operations support different settings.
Edit the offset
Use Surface Offset in the available stack controls or Inspector. A positive value raises the offset and a negative value lowers it relative to the relationship's surface reference. Use explicit length units if needed.
Inspect placement and orientation
Open Stack options where offered. On a face and Where it is control placement; Keep upright and Align to face control orientation. Choose only among the options available for that mode and target.
Reorder a linked object
With one linked child selected, use Move Up or Move Down in the Stack flyout to change its ordering where possible. Check the resulting geometry after a reorder; changing a relationship's order is not the same as changing drawing front/back order.
Remove or commit the relationship
Use Separate when the objects should no longer be linked. Use Merge into one object only when you want a supported live result converted into one object. Undo restores a committed relationship change.
