The scripts cmake_gen.bat and cmake_gen.sh have been added to facilitate batch building of OCCT correspondingly on Windows and Linux platforms.
The files build.bat and install.bat are copied to the build directory by cmake configure procedure to enable batch building and installation on Windows platform.
The scripts occ_build_wasm.bat and occ_build_wasm.sh have been added
to simplify batch building of OCCT with Emscripten (Web Assembly packages) correspondingly on Windows and Linux platforms.
These scripts are configurable through calling files with custom environment wasm_custom_env.bat and wasm_custom_env.sh.
Scripts adm/cmake/bison.cmake and adm/cmake/flex.cmake are refactored to enable actual search for bison and flex.
Apart of standard locations, also sub-folders of 3RDPARTY_DIR whose names contain "bison" and "flex", respectively, are added to search.
Cache variables 3RDPARTY_BISON_EXECUTABLE and 3RDPARTY_FLEX_EXECUTABLE are removed to avoid confusion (they duplicated similar variables without "3RDPARTY_" prefix).
Lex and Yacc files are corrected to match changes made manually in generated files during last years:
- StepFile/step.yacc: correction missing from #22972
- StepFile/step.lex: corrected for compilation (broken by #31060)
- MSVC-specific code is synchronized between StepFile/step.lex and ExprIntrp/ExprIntrp.lex
- Old commented code and duplicate code blocks removed
Commands for execution of Flex and Bison tools in CMake scripts are tweaked to avoid embedding line numbers (with local paths) in generated files.
Scanners and parsers are regenerated from updated source files with modified options.
Note that lex.ExprIntrp.c is regenerated with multiple differences because option -f (fast scanner) was used for generation of previous version (by WOK).
Handle "VTK::" prefix instead of "vtk" used by previous VTK versions for targets.
Corrected unexpected location of endif() and broken indentation.
Obsolete $VTK_USE_FILE is no more included (basing on VTK version check).
Standard_WarningsDisable.hxx/Standard_WarningsRestore.hxx pair is now used to suppress VTK warnings instead of partial disabling.

- AIS_Dimension -> PrsDim_Dimension,
- 'Search Qt4' is renamed into 'Search Qt'. Configuration uses Qt5 from now. For Qt4 use CMake configuration.
- 'Build Inspector' check box is added. It causes 'tools' toolkits compilation. Activates automatically 'Search Qt' control.
- Many Tcl procedures are extended with additional parameter to giving a directory of processed toolkits. The default directory is 'src', inspector directory is 'tools'. This way is similar Inspector compilation implemented in Cmake build procedure.
- Dependency libraries in DEBUG are stored in __TKDEP_DEBUG__. Qt requires it as names of debug and release libraries are different.
-Create a new package BRepPreviewAPI, inherited from BRepPrimAPI to create both, valid and degenerative shapes
-Create a new class BRepPreviewAPI_MakeBox for working with a box
Preview can be vertex, edge, rectangle or box
-BRepPrim_GWedge: in the case of non-valid data, the exception does not happen in the constructor, but at the moment of access to the shape
-BRepPrimAPI_MakeBox: myWedge is now not private, but protected, because used in BRepPreviewAPI_MakeBox which inherits from BRepPrimAPI_MakeBox
-Add tests for checking of a creation a preview in tests/geometry/preview (vertex, edge, rectangle, box)
-Update a command "box": add new parameters
Build tools are updated to support building with Visual Studion 2019 toolset ClangCL (LLVM clang-cl):
- In CMake builds, use of unsupported option "-std=c++0x" is avoided
- Tool genconf recognizes availability of ClangCL toolset and proposes it in the list
- Tool genproj recognizes new compiler specification VCVER=vclang and generates VS 2019 projects for it
Note that vclang configuration puts binaries to folder "vc14" as it is compatible with vc14 CRT.
Code is updated to build with Clang for Windows without errors and warnings:
- In BVH classes, pure virtual destructors are replaced by empty ones, to avoid bogus compiler warning
- In .lex files, pragmas are added to disable warnings in parser code
- In OSD, signature of function _osd_wnt_set_error() is corrected to avoid warning on incorrect use of va_args (undefined behavior)
- In OSD_Host, OSD_Parallel_TBB, warnings on usage of deprecated function are disabled
- In Quantity_ColorRGBA and ViewerTest_CmdParser, incorrect use of predefined macro __FUNCTION__ assuming it was a string literal is avoided
- In Standard_Macro.hxx, code is reordered to handle Clang for Windows appropriately
- In AdvApp2Var_SysBase.hxx, inclusion of obsolete (MSVC-specific) header file is replaced by Standard_TypeDef.hxx
- In Standard_ErrorHandler.hxx, empty statements added to avoid warning on unused class fields
- In IVtkDraw and ViewerTest, interface is corrected to use actual type avoiding unnecessary type casts

OSD_Process::ExecutableFolder() - added method returning executable folder.
Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.
The workflow of updated component can be divided on six parts:
* Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
* Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;
* Heal discrete model: source TopoDS_Shape can contain problems, such as open-wire or self-intersections, introduced during design, exchange or modification of model. In addition, some problems like self-intersections can be introduced by roughly discretized edges. This stage is responsible for analysis of discrete model in order to detect and repair faced problems or refuse model’s part for further processing in case if problem cannot be solved;
* Preprocess discrete model: defines actions specific for implemented approach to be performed before meshing of faces. By default, iterates over model faces and checks consistency of existing triangulations. Cleans topological faces and its adjacent edges from polygonal data in case of inconsistency or marks face of discrete model as not required for computation;
* Discretize faces: represents core part performing mesh generation for particular face based on 2D discrete data related to processing face. Caches polygonal data associated with face’s edges in data model for further processing and stores generated mesh to TopoDS_Face;
* Postprocess discrete model: defines actions specific for implemented approach to be performed after meshing of faces. By default, stores polygonal data obtained on previous stage to TopoDS_Edge objects of source model.
Component is now spread over IMeshData, IMeshTools, BRepMeshData and BRepMesh units.
<!break>
1. Extend "tricheck" DRAW-command in order to find degenerated triangles.
2. Class BRepMesh_FastDiscret::Parameters has been declared as deprecated.
3. NURBS range splitter: do not split intervals without necessity. Intervals are split only in case if it is impossible to compute normals directly on intervals.
4. Default value of IMeshTools_Parameters::MinSize has been changed. New value is equal to 0.1*Deflection.
5. Correction of test scripts:
1) perf mesh bug27119: requested deflection is increased from 1e-6 to 1e-5 to keep reasonable performance (but still reproducing original issue)
2) bugs mesh bug26692_1, 2: make snapshot of triangulation instead of wireframe (irrelevant)
