Detailed Description

Reading options to filter the types of information that are read when CAD files are loaded.

All the m_bRead* fields are boolean options defaulted to A3D_FALSE, which means the related entity is skipped upon reading.

Remarks
Even if these options are very common among CAD formats, some of them may be irrelevant to a specific format.

Field Documentation

◆ m_bReadSolids

A3DBool A3DRWParamsGeneralData::m_bReadSolids

Allows reading of solid parts.

◆ m_bReadSurfaces

A3DBool A3DRWParamsGeneralData::m_bReadSurfaces

Allows reading of surfaces entities.

◆ m_bReadWireframes

A3DBool A3DRWParamsGeneralData::m_bReadWireframes

Allows reading of wireframe entities.

◆ m_bReadPmis

A3DBool A3DRWParamsGeneralData::m_bReadPmis

Allows reading of PMIs.

◆ m_bReadAttributes

A3DBool A3DRWParamsGeneralData::m_bReadAttributes

Allows reading of non-geometric information linked to entities and files.

Remarks
Attributes linked to solids and entities, such as material and density, are always read, even if m_bReadAttributes is A3D_FALSE.

◆ m_bReadHiddenObjects

A3DBool A3DRWParamsGeneralData::m_bReadHiddenObjects

Allows reading of representation items which are marked as hidden in the CAD file. Default is A3D_TRUE. When set to A3D_FALSE, representation items considered hidden in the CAD file won't be kept in the resulting PRC. This can be useful when the objective is to observe the visible appearance of the resulting PRC.

Remarks
This option only impacts representation items. Reading of assembly-level entities (parts and product occurrences) is not affected, may the CAD file identify them as hidden or not.
Warning
Setting m_bReadHiddenObjects to false when reading PMIs, Views or complex assemblies may lead to unexpected behavior due to the potential for removal of bodies referenced by residual PMI or Views.

◆ m_bReadConstructionAndReferences

A3DBool A3DRWParamsGeneralData::m_bReadConstructionAndReferences

Allows reading of construction entities, such as planes and axes.

◆ m_bReadActiveFilter

A3DBool A3DRWParamsGeneralData::m_bReadActiveFilter

Allows reading of only data stored in the active filter or on layers corresponding to the active filter.

◆ m_eReadingMode2D3D

A3DEReadingMode2D3D A3DRWParamsGeneralData::m_eReadingMode2D3D

If applicable, choose whether reading 2D drawing, 3D model or both. For IGES format, kA3DRead_Both is not available and will default to kA3DRead_3D.

◆ m_eReadGeomTessMode

A3DEReadGeomTessMode A3DRWParamsGeneralData::m_eReadGeomTessMode

Select between reading geometry, tessellation or both.

◆ m_eDefaultUnit

A3DEUnits A3DRWParamsGeneralData::m_eDefaultUnit

DefaultUnit option restricted to those formats where unit never exists or is unreliable (U3D, CGR, STL, VRML)

  • If it is different than kA3DUnitUnknown, the default unit used is the one defined with this enum
  • If it is set to kA3DUnitUnknown, the default unit is considered unknown and the value is 1.0.

◆ m_bReadFeature

A3DBool A3DRWParamsGeneralData::m_bReadFeature

Allows reading of model feature tree.

Version
10.2

◆ m_bReadConstraints

A3DBool A3DRWParamsGeneralData::m_bReadConstraints

Allows reading of assembly constraints.

Version
14.0

◆ m_iNbMultiProcess

A3DInt32 A3DRWParamsGeneralData::m_iNbMultiProcess
Deprecated:
. Not used anymore.

◆ m_uiSearchTextureDirectoriesSize

A3DUns32 A3DRWParamsGeneralData::m_uiSearchTextureDirectoriesSize

The size of m_ppcSearchTextureDirectories array.

Version
8.0

◆ m_ppcSearchTextureDirectories

A3DUTF8Char** A3DRWParamsGeneralData::m_ppcSearchTextureDirectories

Additional search directories for texture files.

Version
