From: gka Date: Thu, 5 Jul 2018 16:10:31 +0000 (+0300) Subject: 0029846: Data Exchange - STEP validation properties support is obsolete X-Git-Tag: OCCT_VC2017_73~64 X-Git-Url: http://git.dev.opencascade.org/gitweb/?a=commitdiff_plain;h=ffe1b14331b448bcb50d8ca137af7f2d9e9aad1b;p=occt.git 0029846: Data Exchange - STEP validation properties support is obsolete Name of the PROPERTY_DEFINITION entity for validation properties is changed to "geometric validation property" according to the current version of the recommended practices. For compatibility with older definitions (with underscores) the check is made using string with underscores replaced by spaces. --- diff --git a/src/STEPConstruct/STEPConstruct_ValidationProps.cxx b/src/STEPConstruct/STEPConstruct_ValidationProps.cxx index d8e9193b5d..8172591486 100644 --- a/src/STEPConstruct/STEPConstruct_ValidationProps.cxx +++ b/src/STEPConstruct/STEPConstruct_ValidationProps.cxx @@ -57,6 +57,7 @@ #include #include #include +#include #include #include #include @@ -338,7 +339,7 @@ Standard_Boolean STEPConstruct_ValidationProps::AddProp (const StepRepr_Characte { // FINALLY, create a structure of 5 entities describing a link between a shape and its property Handle(TCollection_HAsciiString) PropDefName = - new TCollection_HAsciiString ( "geometric_validation_property" ); + new TCollection_HAsciiString ( "geometric validation property" ); Handle(TCollection_HAsciiString) PropDefDescr = new TCollection_HAsciiString ( Descr ); Handle(StepRepr_PropertyDefinition) propdef = new StepRepr_PropertyDefinition; propdef->Init ( PropDefName, Standard_True, PropDefDescr, target ); @@ -493,11 +494,20 @@ Standard_Boolean STEPConstruct_ValidationProps::LoadProps (TColStd_SequenceOfTra Handle(StepRepr_PropertyDefinitionRepresentation) PDR = Handle(StepRepr_PropertyDefinitionRepresentation)::DownCast ( enti ); - // check that PDR is for validation props + // Check that PDR is for validation props.
