# A3DEntityIsBaseType

A3DBool `A3DEntityIsBaseType`(const A3DEntity *pEntity)
  `A3DBool` A3DEntityIsBaseType(const `A3DEntity`* pEntity)

  Indicates whether an entity base type corresponds to the `kA3DTypeRootBase`type enumeration.

  This function returns a value of `TRUE`if an entity type is based on the abstract root type for any PRC entity (with or without graphic data). Such an abstract root type is identified by the `kA3DTypeRootBase`type enumeration.

  > Because this function does not return `A3DStatus`the internal thread safety policy is to wait for the availability of the API.

  > 2.0 You may need to use this function to sort entities for particular processing.
