Readers

ACIS
- Fixed case of same edge used in wire and body
- Fixed reversed surface of face
Cadds
- Improved handling of single precision CADDS Files.
Catia V4
- View 2D , suppress redundant information of angle of view. -Previous version the angle of view present in field angle ( Angle() method ) AND in Dtk_transfo & TransformationMatrix () -Now the Dtk_transfo & TransformationMatrix () will return identity matrix, the view angle is only with Angle() method
Catia V5
- Added CATIA V5-6R2017 also known as R27 support (available only with Dtk_Node/Dtk_Body integration)
- 2D: Improved Annotation Placement with view rotation angle.
- 2D: Removed Clipping planes from views because elements are clipped from the reading and so clipping planes are useless.
Catia V6
- Adds and Modify metadata storage.
- Improved support of the flexible Products.
DWG
- 2D: Fixed entity coordinate system matrix and elevation of 2d polyline
IFC
- Improved mockup
- Fixed metadatas
- Fixed element hierarchy
Iges
- Read attributes on Basis Surface

Parasolid (PSKERNEL based Parasolid Reader):
- Fixed problem with extension surface .
- Fixed problem for blend with singularity
Pdf
- Added line styles
Proe/Creo Reader
- Support Creo4
