STEPControl_Reader Class Reference

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);. More...
