Changes

0025415: Data Exchange - Invalid result of loading a STEP file

Handling of special case found on some STEP files produced by FPX Expert 2013 (PCB design system):
edge curve is line displaced from its true position but with correct direction;
we shift the line in this case so that it passes through vertices correcty.

Protection against possible exception in writing XDE.

0033596: Documentation - Incorrect default value read.step.tessellated

Default value of read.step.tessellated corrected.

0033611: Data Exchange - Incorrect header guard for STEP property

Incorrect header guard fixed.

0033641: Data Exchange, Step Import - Changing default value for metadata flag

Value for myMetaMode flag changed from 'false' to 'true'.

0033602: Data Exchange, Step - Carriage return removing

Carriage removing integrated

0033603: Data Exchange, Step Import - Crash reading corrupted STEP file

Crash fixed by checking IsNull().

0033631: Data Exchange, Step import - Crash by reading STEP file

Creating Poly_Triangulation from ComplexTriangulatedSurfaceSet was fixed.

0033638: Data Exchange, Step Import - Style for tessellated object missed

TransferBRep_ShapeBinder used for tessellated face.

0029241: Data Exchange - Empty shape after reading STEP file.

Entity mechanical_design_and_draughting_relationship and function for its transfer added.

0031601: Modeling Algorithms - BRepOffset_Tool Segmentation Fault

Added protection against null pointer dereferencing.
Modified BRepOffset_MakeOffset::MakeThickSolid method.
Fixed the problem with negative volume values.
Fixed several unit tests and added a new one.

0033367: Modeling Algorithms - Normal projection or BOP problem [Regression]

Fixed passing of an incorrect curve into GeomAdaptor::MakeCurve() function.

0033410: Data Exchange, Step Import - TRIANGULATED_FACE from STEP where there are no pnval entries

Problem fixed by using array of nodes in case when aPnindices is empty.

0033616: Application Framework - Using filter while reading XBF may result in unresolved links

- Added tracking of unresolved links for TreeNodes;
- Test case added.

0033560: PARASOLID Import - XT importer raises exception SIGFPE Arithmetic Exception

Prevent division by zero in exceptional cases when vector of parameters contains only a single value.

0033661: Data Exchange, Step Import - Tessellated GDTs are not imported

Add processing of tessellated_annotation_occurrence.
Add test cases.
