Smart Duplication provides enhanced versions of the built-in Duplicate and Delete operators, extended with context-aware capabilities to ease multi-object and modifier based workflows.

• The Smart Duplication operator (Ctrl+D by default) duplicates the selected objects and, optionally: 
  • Duplicates the modifiers that refer to them.
  • Duplicates the objects referenced by their modifiers.
  • Duplicates their children.
  • Adds the new objects to the same collections as the originals.

• The Smart Delete operator (Ctrl+X by default) deletes selected objects, and, optionally: 
  • Deletes the modifiers that refer to them.
  • Deletes the objects referenced by their modifiers.
  • Deletes their children.
  • Removes them from the collections they were part of.

• The Select References operator selects objects referenced in modifiers by the current selection or the ones referencing the current selection in their modifiers.
• Smart Duplication supports every modifier type that references other objects.
