Utils

Classes : Dtk_MetaData : add method Dtk_ErrorStatus GetUnits( Dtk_string& outUnits ) const; to check if Units exist or not and get it
Tessellation : Add new method tess_getBoundariesFromMeshFace(const Dtk_MeshPtr &mesh, const Dtk_mesh_face *inFace, Dtk_tab<Dtk_tab<Dtk_MeshPolylinePtr> > &outBoundaries) this method use new class Dtk_MeshPolylinePtr in place of Dtk_PolylinePtr to conserve relation between vertex and point of polyline Dtk_MeshPolylinePtr contain some methods : GetNbVertex() return number of points in polyline GetVertexInd(ival) return index from mesh vertex of ival point GetTopoID() return TopoID of edge from Dtk_Body

Readers

ACIS
- Improved attributes management
Catia V5
- Added CATIA V5-6R2021 (R31) support.
- 3D:
  - Added edges attribut.
  - Metadata unit improvement.
- FDT/2D:
  - Named Views are not provided as Dtk_Camera node anymore.
    They are now provided as Dtk_ModelDisplay nodes - with DTK_TYPE_CAMERA sub-type - to be consistent with other readers.
    Moreover the default named view - the opening view - has the Dtk_ModelDisplay::IsActivated() method returning DTK_TRUE.
  - Changes with the Captures 'IsCurrent' status:
    This status can not be accessed by the Dtk_ModelDisplay::IsActivated() method anymore.
    It can now be accessed from the 'V5CaptureIsCurrent' ModelDisplay Info attribute.
Catia V6 / 3DExperience
- Added support the Parameter Set data

DWG
- 3D :
  - Added normalization of all bodies
  - Improved management of CIRCLE entities with thickness
  - Improved support of 3D faces read as mesh entity (to retrieve it, use Dtk_Node::GetDtk_MeshPtr() method)
- 2D :
  - Added support for block type entities (read as Dtk_CompositeEntityPtr)
  - Added support for solid entity (read as Dtk_PolylinePtr)
  - Improved management of symbols of PROXY type entities (read as Dtk_SymbolPtr)
  - Improved management of the FCF (Feature Control Frame) type tolerance available as Dtk_GeometricalTolerancePtr
  - Improved texts mangement and dimension orientation
Ifc
- Improve normal computation of meshs
- Improve IfcPolygonalFaceSet management
- Fix Axis management
- Fix IfcRevolvedAreaSolid management
- Fix files with multiple IfcSites. Their transformation matrices are now applied as it was done before v2021.1, since they define multiple local coordinate systems.
Iges
