Implementation of classes that help to explore model BRep representation of a part in Manufacturing Toolkit examples.

Overview

This helper is used to explore the model, BRep representation of a ModelData_Part and process specific shapes using MTK tools.

Implementation

To explore the model and process ModelData_Part s, it's need to create an inheritor from the ModelData_ModelElementVoidVisitor and override the part processing method void operator() (const ModelData::Part& thePart). For this purpose, two classes were created: ShapeProcessor and SolidProcessor.
ShapeProcessor is used to explore BRep representation and process each unique ModelData_Solid or ModelData_Shell by passing it to virtual method void ProcessSolid (const ModelData::Solid& theSolid) or void ProcessShell (const ModelData::Shell& theShell). These methods should be overridden in child classes.

class ShapeProcessor(mtk.ModelData_ModelElementVoidVisitor):
    def __init__(self):
        super().__init__()
        self.myPartIndex = 0
 
    def __call__(self, thePart: mtk.ModelData_Part):
        aPartName = "noname" if thePart.Name().IsEmpty() else thePart.Name()
        
        aBodyList = thePart.Bodies()
        i = 0
        for aBody in aBodyList:
            aShapeIt = mtk.ModelData_ShapeIterator(aBody)
            for aShape in aShapeIt:
                if aShape.Type() == mtk.ShapeType_Solid:
                    print("Part #", self.myPartIndex, " [\"", aPartName, "\"] - solid #", i, " has:", sep="")
                    i += 1
                    self.ProcessSolid(mtk.ModelData_Solid.Cast(aShape))
                elif aShape.Type() == mtk.ShapeType_Shell:
                    print("Part #", self.myPartIndex, " [\"", aPartName, "\"] - shell #", i, " has:", sep="")
                    i += 1
                    self.ProcessShell(mtk.Shell.Cast (aShape))
        self.myPartIndex += 1
 
    @abstractmethod
    def ProcessSolid(self, theSolid: mtk.ModelData_Solid):
        pass
 
    @abstractmethod
    def ProcessShell(self, theShell: mtk.ModelData_Shell):
        pass

SolidProcessor is used to explore BRep representation and process each unique ModelData_Solid by passing it to virtual method void ProcessSolid (const ModelData::Solid& theSolid). This method should be overridden in child classes.

class SolidProcessor(mtk.ModelData_ModelElementVoidVisitor):
    def __init__(self):
        super().__init__()
        self.myPartIndex = 0
 
    def __call__(self, thePart: mtk.ModelData_Part):
        aPartName = "noname" if thePart.Name().IsEmpty() else thePart.Name()
 
        aBodyList = thePart.Bodies()
        i = 0
        for aBody in aBodyList:
            aShapeIt = mtk.ShapeIterator(aBody)
            for aShape in aShapeIt:
                if aShape.Type() == mtk.ShapeType_Solid:
                    print("SHAPE")
                    print("Part #", self.myPartIndex, " [\"", aPartName, "\"] - solid #", i, " has:", sep="")
                    i += 1
                    self.ProcessSolid (mtk.ModelData_Solid.Cast (aShape))
        self.myPartIndex += 1
 
    @abstractmethod
    def ProcessSolid(self, theSolid: mtk.ModelData_Solid):
        pass
