Summary0005303: Integration of changing STEP translator after CAX-IF TR13J
DescriptionIntegration of changing STEP translator after CAX-IF TR13J
Additional information
and documentation updates		Documentation remark, added by ATP 2004-04-20 09:52:15:

New features:
This patch gives us a possibility for reading the information from STEP files about materials and geometric dimensions and tolerances using the XDE reader.

In the framework of the regular CAX-IF activity, Open CASCADE has extended its
STEP Interface to handle STEP materials, dimensions and geometric tolerances.
Improvements:
We have corrected some problems in the existing algorithm that were found during
the implementation of new features.

Modified entities:
For realisation new mechanism of reading we create new classes for some STEP
entities in existing packages:
  RWStepBasic_RWConversionBasedUnitAndMassUnit
  RWStepBasic_RWMassMeasureWithUnit
  RWStepRepr_RWCompositeShapeAspect
  RWStepRepr_RWDerivedShapeAspect
  RWStepRepr_RWExtension
  RWStepRepr_RWReprItemAndLengthMeasureWithUnit
  RWStepRepr_RWShapeAspectDerivingRelationship
  RWStepShape_RWShapeRepresentationWithParameters
  StepBasic_ConversionBasedUnitAndMassUnit
  StepBasic_MassMeasureWithUnit
  StepRepr_CompositeShapeAspect
  StepRepr_DerivedShapeAspect
  StepRepr_Extension
  StepRepr_ReprItemAndLengthMeasureWithUnit
  StepRepr_ShapeAspectDerivingRelationship
  StepShape_ShapeRepresentationWithParameters
and two new packages:
  StepDimTol and RWStepDimTol.
Also we create new classes in the package XCAFDoc which using for creation new
attributes in the XCAF document and working with them:
  XCAFDoc_Datum
  XCAFDoc_DimTol
  XCAFDoc_DimTolTool
  XCAFDoc_Material
  XCAFDoc_MaterialTool
and make changes in the classes:
  XCAFDoc_DocumentTool
  XCAFDoc_ShapeTool
for using new attributes.
Also we make needed changes in the main classes for reading and writing STEP
files into XCAF document:
  STEPCAFControl_Reader
  STEPCAFControl_Writer

More information you can find in the corresponding .cdl files.

Classes from packages STEPConstruct, STEPControl, APIHeaderSection and ShapeFix
were changed for correction of some problems (see "Improvement").
