Third parties : New Version Tiff image format management updated to 4.6.0t
Improve 3D boundary curves computing

Readers

Acis
- Improved management of curves in case of bad/empty vertex (now not trimmed by domain)
- Improved management of body name
- Improved handling of file with bad curves
Catia V4
- Improvement of vertices unicity. For that, we create all 3D edges curve.
- Improvement of topology orientation (coedges, loops, faces)
Catia V5
- 2D:
  - We now process CGM Pictures as Dtk_CompositeEntity by default. You can modify this by calling CatiaV5Reader::SetConfigV5ReadCGMPicturesAsCompositeEntities function.
  - We now process 2DComponent as Dtk_CompositeEntity.
- 2D/FDT: We now clip dimension leaders through frames
- FDT:
  - We now process NOA entity as Dtk_CompositeEntity.
- For "Manage Representations" in a Catiav5 assembly, the Dtk_Component::CatalogComponentType node of a ".model" file is replaced by the Dtk_Component::PrototypeComponentType node of the "MASTER" to be able to instantiate it.
- Improved computation of NURBS
Catia V6 / 3DExperience
- "3DXML for review" tree: put after start API CatiaV6Reader::SetCfgChooseV6Name(2) to display 3DxmlPlayer tree nodes names. By default, this is equal to 1 corresponding to Catiav5 software tree node names
- Changed of persistent name. Adding the UUID of the part
Cgr
- Added option ReadMeshOnly to read mesh data only, without any additional informations such as curves, mesh face boundaries or center/radius/axis/etc of cylinders and circles.
DWG
- 2D :
  - Improved management of ordinate dimension (read as Dtk_DimensionPtr)
Fusion 360
- New Version Added support for versions up to 2.0.19426
IFC
- Changed management of Dtk_Metadata for IFCPROPERTYSET : we don't create Dtk_Node with MetaDataType anymore, we only store the corresponding set of Dtk_Metadata in the Instance Dtk_Component. We also don't store Dtk_Metadata on Prototype Dtk_Component anymore.
- Fixed issue with mockups containing inner boundaries.
- Improved robustness for corrupted files.
Iges
- Add support for Name property
Inventor
- New Version Added support for Inventor 2025
- Added support of curves as wire from Mark feature
- Improved color management
- Improved visibility management of surface bodies
- FDT :
  - Added information of text style as geometry, on additional geometries for underlined and breakthrough lines (to retrieve it, use Dtk_Info::FindAttribute(L"IsTextStyleGeom",outVal) method)
  - Added welding type on the Dtk_SymbolPtr for Welding Symbol (to retrieve it, use Dtk_Symbol::SymbolType() method)
  - Improved reading of FDT entities
  - Improved FDT visibility in a view
Navisworks
- Improved geometry read
Proe/Creo Parametric
- New Version Added support for last version Creo 11.0
- Nurbs surface processing improved
- Reader stability/security improved
- 2D :
  - Improved views scale reading
  - Improved geometric tolerance reading
  - Improved datum tag reading
Qif
- Added support for global project scale
- Added support for document attributes (Dtk_Metadata on root component with type TypeFileProperty)
- Fix topology reading problem of surface/coedge orientation
- Fix units of instance position in assembly
- FDT :
  - Added support for composite geometrical tolerances
  - Added semantic retrieving for flatness geometrical tolerances
  - Enhanced overall modifiers support
  - Fix circular leader graphic
Revit
- New Version Added support for Revit 2025
- Generalized usage of Virtual components for elements that does not have physical reality (only existing for grouping) : Levels, Categories, host objects as "Curtain Wall"
- Added "Level of detail" geometry filter handling. By default, used LOD is the default 3d view one ({3D}), or "Detailed" if no such view exists
- Added RevitReader::SetConfigLevelOfDetail to enforce geometry filtering using a specific level of detail
- Added attribute in Dtk_ModelDisplay info : "_DTK_USE_LOD" to identify which level of detail is applied to a Revit view
- Added "Curtain Wall" retrieving and grouping. Having no physical reality, it appears as a Virtual component in the assembly tree, its geometry is describe by its children
- Added utility metadata for Railings (prefixed by "Dtk_") : Top Railing identification, Reference to stairs
- Family property retrieving improved : now recognise built-in "System Family"
- Improved Type property retrieving
- Fix component tree that could have several "Level" with same name
Solid Edge
- Improved parsing
- 3D :
  - Improved sub assembly files loading, especially on Unix systems
  - Fixed instance component name in case of missing associated prototype that would be set to entire file path
- 2D :
  - Revamped dimension entities, fixing remaining leader orientation, now providing semantic information and supporting display modes (Nominal, Tolerance, Class...)
Solidworks
- New 2D Reader mode
  - There are now two modes for reading drawing files (SLDDRW extension). The already existing one that reads graphic data, and the new one that reads semantic data. See Modes for reading drawing files (SLDDRW extension) for more information.
- Improved parsing
- Fixed missing & removed extra sketch curves
- 3D/FDT:
  - Removed duplicate Dtk_InfoPtr on Dtk_Text corresponding to a sign ('+', '-', '+-') in dimensions. The same Dtk_InfoPtr is found on the Dtk_Text corresponding to the numerical value.
  - Improved processing of angular dimension (callout named sft_nscsDia and sft_nscsAng in Solidworks)
- 2D Graphical:
  - Added Dtk_TextStyle::AttributeStrikethrough attributes to texts.
Step
- Added reading of PersistentName on FDT
- FDT Placeholder : improved case of Dimension with plus-minus (now on up-down lines)
Unigraphics
- New Version Added support for last version NX 2312 Series (until 2312.7000)
- 3D/FDT:
  - Added missing link for PMI
  - Fixed assembly feature definition
  - Fixed NX2312 modeldisplay definition
  - Remove duplicated metadata
- 2D:
  - Fixed missing entities

Writers

PLMXML
- First version supports assembly, instances, and metadatas
Step
- Case of Multi-file writing : added ANCHOR on main shape representation
- FDT Dimension : modifiers are written only if general (not on lower/upper limit)
- Improvements on writing FDT Placeholder (leader lines)
