Open CASCADE Technology 6.6.0
|
Reads STEP files, checks them and translates their contents
into Open CASCADE models. The STEP data can be that of
a whole model or that of a specific list of entities in the model.
As in XSControl_Reader, you specify the list using a selection.
For the translation of iges files it is possible to use next sequence:
To change translation parameters
class Interface_Static should be used before beginning of
translation (see STEP Parameters and General Parameters)
Creation of reader - STEPControl_Reader reader;
To load s file in a model use method reader.ReadFile("filename.stp")
To print load results reader.PrintCheckLoad(failsonly,mode)
where mode is equal to the value of enumeration IFSelect_PrintCount
For definition number of candidates :
Standard_Integer nbroots = reader. NbRootsForTransfer();
To transfer entities from a model the following methods can be used:
for the whole model - reader.TransferRoots();
to transfer a list of entities: reader.TransferList(list);
to transfer one entity Handle(Standard_Transient)
ent = reader.RootForTransfer(num);
reader.TransferEntity(ent), or
reader.TransferOneRoot(num), or
reader.TransferOne(num), or
reader.TransferRoot(num)
To obtain the result the following method can be used:
reader.NbShapes() and reader.Shape(num); or reader.OneShape();
To print the results of transfer use method:
reader.PrintCheckTransfer(failwarn,mode);
where printfail is equal to the value of enumeration
IFSelect_PrintFail, mode see above; or reader.PrintStatsTransfer();
Gets correspondence between a STEP entity and a result
shape obtained from it.
Handle(XSControl_WorkSession)
WS = reader.WS();
if ( WS->TransferReader()->HasResult(ent) )
TopoDS_Shape shape = WS->TransferReader()->ShapeResult(ent);

Public Member Functions | |
STEPControl_Reader () | |
Creates a reader object with an empty STEP model. | |
STEPControl_Reader (const Handle< XSControl_WorkSession > &WS, const Standard_Boolean scratch=Standard_True) | |
Creates a Reader for STEP from an already existing Session Clears the session if it was not yet set for STEP | |
Handle_StepData_StepModel | StepModel () const |
Returns the model as a StepModel. It can then be consulted (header, product) | |
Standard_Boolean | TransferRoot (const Standard_Integer num=1) |
Transfers a root given its rank in the list of candidate roots Default is the first one Returns True if a shape has resulted, false else Same as inherited TransferOneRoot, kept for compatibility | |
virtual Standard_Integer | NbRootsForTransfer () |
Determines the list of root entities from Model which are candidate for a transfer to a Shape (type of entities is PRODUCT) | |
void | FileUnits (TColStd_SequenceOfAsciiString &theUnitLengthNames, TColStd_SequenceOfAsciiString &theUnitAngleNames, TColStd_SequenceOfAsciiString &theUnitSolidAngleNames) |
Returns sequence of all unit names for shape representations found in file |
