# A3DRiRepresentationItemDeepCopy

A3DStatus `A3DRiRepresentationItemDeepCopy`(const A3DRiRepresentationItem *pRi, A3DRiRepresentationItem **ppNewRi)
  `A3DStatus` A3DRiRepresentationItemDeepCopy(const `A3DRiRepresentationItem`* pRi, `A3DRiRepresentationItem`** ppNewRi)

  Create a new representation item by making a deep copy.

  Representation item data are copied, except coordinate system and surface are shared for optimization as for the rest of the model. There are some limitations:

  - ID is reset to 0, but topological item ids are kept.
  - Stored links are lost when a representation item is copied independently of the rest of the model. It’s up to the user to create new ones. An entity reference sets to describe the link between a datum plane and a body plane face will be removed.
  - Drawing block is not implemented.
  - Feature data on TfSet are not copied.

  Returns

  > `A3D_SUCCESS`on success, or an error code on failure
