# A3DMiscEntityReferenceData

struct `A3DMiscEntityReferenceData`

  Structure that identifies the referenced entity and that provides a new coordinate system.

  > 2.0

  If the type of the referenced entity is topology, `m_pEntity`is an `A3DMiscReferenceOnTopology`object of type `kA3DTypeMiscReferenceOnTopology`, which contains the reference to the topological body. In addition to containing a reference to the topology entity, the `A3DMiscReferenceOnTopology`entity defines the topology item type and includes indexes to items in the global settings, such as color and layer.

  If the type of the referenced entity is nottopology, the `m_pEntity`member can directly reference an object that has one of the types defined in Referenceable Non-Topological Entities. (`m_pEntity`can also be NULL.)To get the type of the entity referenced by the `m_pEntity`member, use the `A3DEntityGetType()`function.
