Detailed Description
-
struct A3DRWParamsGeneralData
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 toA3D_FALSE, which means the related entity is skipped upon reading.Remark
Even if these options are very common among CAD formats, some of them may be irrelevant to a specific format.

A3DBool m_bReadAttributes
Allows reading of non-geometric information linked to entities and files.
Remark
Attributes linked to solids and entities, such as material and density, are always read, even if
m_bReadAttributesisA3D_FALSE.
-
A3DBool m_bReadHiddenObjects
Allows reading of representation items which are marked as hidden in the CAD file.
Default is
A3D_TRUE. When set toA3D_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.Remark
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_bReadHiddenObjectstofalsewhen 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.
-
A3DBool m_bReadConstructionAndReferences
Allows reading of construction entities, such as planes and axes.
-
A3DBool m_bReadActiveFilter
Allows reading of only data stored in the active filter or on layers corresponding to the active filter.
-
A3DEReadingMode2D3D m_eReadingMode2D3D
If applicable, choose whether reading 2D drawing, 3D model or both.
For IGES format,
kA3DRead_Bothis not available and will default tokA3DRead_3D.
-
A3DEReadGeomTessMode m_eReadGeomTessMode
Select between reading geometry, tessellation or both.
-
A3DEUnits 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.
-
A3DInt32 m_iNbMultiProcess
- Deprecated:
. Not used anymore. This will be removed in version 2026.1.0.
-
A3DUns32 m_uiSearchTextureDirectoriesSize
The size of m_ppcSearchTextureDirectories array.
- Version
8.0
-
A3DUTF8Char **m_ppcSearchTextureDirectories
Additional search directories for texture files.
- Version
8.0
-
A3DUns32 m_uiSearchMaterialLibraryFilesSize
The size of m_ppcSearchMaterialLibraryFiles array.
- Version
24.2
-
A3DUTF8Char **m_ppcSearchMaterialLibraryFiles
Additional material library files.
- Version
24.2
-
A3DBool m_bTreatLongWireframeAsConstructionAndReferences
Remove long wireframe when m_bReadConstructionAndReferences is set to false.
Threshold value to determine long wireframe is set via m_dLongWireframeThreshold.
Remark
This option will only apply when m_bReadWireframes is set to true. When m_bReadWireframes is set to false, all wireframes will be removed, no matter the value of m_dLongWireframeThreshold.
- Version
24.4
-
A3DDouble m_dLongWireframeThreshold
Define the threshold for long wireframe.
Any wireframe with a bounding box longer than this value will be removed if m_bTreatLongWireframeAsConstructionAndReferences is true, and m_bReadConstructionAndReferences is false
Remark
Default value is 24690.0
- Version
24.4
