0033099: Data Exchange, Step Import - Wrong PMI values in GDT
measure_with_unit entity is changed to be translated as Handle(Standard_Transient) and to be processed later, depending on the underlying type being used.
0033484: Data Exchange, Step Import - Pretessellated geometry is translated incompletely
Added proper translation for TessellatedCurveSet and ComplexTriangulatedSurfaceSet.
0030024: Data Exchange - STEP, IGES export support of BRep shapes based on tessellated geometry
Support of reading and writing tessellated geometry is added for the following STEP entities:
- triangulated face
- complex triangulated face
- tessellated shell
- tessellated solid
- tessellated shape representation
Models without BRep geometry (mesh formats like STL, OBJ and so on) are supported for writing to STEP.
New parameters are added to enable/disable tessellated geometry reading and writing:
- read.step.tessellated (On/Off/OnNoBRep) (On by default)
- write.step.tessellated (On/Off/OnNoBRep) (OnNoBRep by default)
OnNoBRep - tessellation is read/written only for entities for which there is no BRep representation.
Faces with poly triangulation are written in STEP as triangulated face entities with one coordinates list per face.
Only one poly triangulation per face (returned by BRep_Tool::Triangulation) is written to STEP.
Update initial visible status of SupplementalGeometry to visible.
To update this value on API side after, you need to found a free label
contains attribute "XCAFDoc::SupplementalContainerGUID()" and set invisible attribute
XCAFDoc::InvisibleGUID()
Updated import methods to add supplemental geometry as a reference to the PMI
Updated export methods to handle supplemental geometry as a special type.
Created new GUID for supplemental geometry container - compound contains all sup. geom. shapes.
Created new GUID for supplemental geometry label - supplemental geometry shape.
Created new GUID for supplemental geometry reference - relation for depends on.
Supplemental geometry: surfaces and curves.
- Add support of the control directives ( "\X2\" "\X4" "\X\" "\P*\" "\S\");
- Make param "read.stepcaf.codepage" base for conversion inside StepData instead of CAF;
- Rename "read.stepcaf.codepage" to "read.step.codepage".
- Add ISO 8859-1 - 9 code pages for conversion
- Add Resource_FormatType_NoConversion format type, that indicates non-conversion behavior
- Update old test cases that contain control directives
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
"endl" manipulator for Message_Messenger is renamed to "Message_EndLine".
The following entities from std namespace are now used
with std:: explicitly specified (from Standard_Stream.hxx):
std::istream,std::ostream,std::ofstream,std::ifstream,std::fstream,
std::filebuf,std::streambuf,std::streampos,std::ios,std::cout,std::cerr,
std::cin,std::endl,std::ends,std::flush,std::setw,std::setprecision,
std::hex,std::dec.
STEPCAFControl_Reader::SourceCodePage() - added property defining text encoding
for converting names within STEPCAFControl_Reader::ReadNames() method.
Added associated "read.stepcaf.codepage" parameter,
which default value is Resource_UTF8, preserving current behavior.
Resource_FormatType enumeration has been extended by UTF8 and SystemLocale values.
Resource_Unicode - added conversion methods taking Resource_FormatType as argument.
GetName command has been corrected to NOT replace non-Latin symbols.
Added protections to avoid exceptions for null objects.
For reading entity StepShape_ToleranceValue was added reading lower and upper bounds represented by entities "StepRepr_ReprItemAndMeasureWithUnit" or "StepRepr_MeasureRepresentationItem"
Use .get() method instead of operator->() where result can be NULL.
STEPCAFControl_Reader::ReadLayers(), XCAFDoc_ColorTool,
XCAFDoc_LayerTool::SetVisibility() - fixed static functions syntax.
Various performance improvements in STEP read/write algorithms:
- Search for the label of a shape or component shape is improved using map mechanism instead of brute force iteration.
- Invariant FindEntities() is moved out of the loop in the method getStyledItem in STEPCAFControl/STEPCAFControl_Writer.cxx.
- A pointer to the end of binders chain is added in Transfer_Binder class to speed up adding a binder to the chain.
- Small fixes are added to eliminate excess copying of handles, calls of handle DownCasts and so on.
Stack overflow is removed during destruction of STEP model with long chains of Transfer_Binder.
It is possible to use the Draw commands ReadStep and WriteStep to read/write from the session without accessing the disk file (use '.' for the file name).
Performance test cases for STEP reading/writing have been added.
In the method STEPCAFControl_Reader::ExpandShell protection for case when entity ""Connected_Face_Set" contains not only "FACE" entities ( for example "VERTEX_POINT" entities) was added.
Implemented semantic PMI names translation from STEP to XCAF in OCCT:
- [Get/Set]SemanticName functions added to XCAFDimTolObjects_*Object classes
- X[Get/Set]GDTSemanticName draw commands added
- test case added
Fix processing of subshape names in STEP in reading and writing.
Replace creating subshapes in Document as tree (invalid) with plain subshapes structure.
Update test cases.
Use of Cotire tool is introduced for acceleration of CMake builds, by usage of precompiled headers.
CMake option BUILD_USE_PCH is added to enable / disable use of precompiled headers
When precompiled headers are used, additional compiler macros are defined globally in the build system to avoid problems due to different order of included files:
- NOMINMAX is defined on Windows to prevent defining "min" and "max" as macros by windows.h
- STRSAFE_NO_DEPRECATE and _SCL_SECURE_NO_WARNINGS are defined on Windows to prevent declaring functions of standard C library as deprecated by #pragma, and other warnings in system headers
- GL_GLEXT_LEGACY and GLX_GLEXT_LEGACY are defined to ensure that only OCCT's own glext.h is used
- __STDC_FORMAT_MACROS is defined to have standard C print format macros always defined
Code is corrected to avoid conflicts with system headers and in case of compiling together as unity builds (partially):
- Some locally defined variables in TKV3d, TKHLR are renamed to be unique
- Duplicated definitions of macros and global functions are eliminated in TKSTEP
- Useless header WNT_UInt.hxx is removed
- Usage of local variables conflicting with X11 macro is avoided in Draw_Viewer.cxx
- Local variables in AIS_ConcentricRelation.cxx are renamed to avoid conflict with macros defined in windows.h
- HXX files containing code are renamed to PXX or merged with corresponding CXX files.
IVtkTools classes are corrected to avoid compiler warnings disabled in non-PCH builds by inclusion of VTK headers.
Useless pragmas disabling warnings on MSVC are removed

In order to avoid using empty strings in the names of the assemblies in the XCAF document after reading step file for cases when description or name is defined by only 1 space character method TCollection_AsciiString::Length()
was replaced on the method TCollection_AsciiString::UsefullLength().
