  Variables

  - `m_pcRootDirLogicalName`
  - `m_bAllowSearchInOtherLogicalNames`

Variables

A3DUTF8Char *`A3DRWParamsCatiaV4Data.``m_pcRootDirLogicalName`
  `A3DUTF8Char`*

  Only used if `A3DRWParamsAssemblyData::m_bUseRootDirectory`is `A3D_TRUE`.

  If so, the load function first searches subparts in the same directory as the head of the assembly. This member enables to define the LogicalName used to perform this root search.

A3DBool `A3DRWParamsCatiaV4Data.``m_bAllowSearchInOtherLogicalNames`
  `A3DBool`

  A value of `A3D_TRUE`specifies that the search can be also performed in other directories.

  A value of `A3D_FALSE`specifies that the search should be done only in the real logical name of the file.
