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.

using namespace cadex;
 
class ShapeProcessor : public ModelData::ModelElementVoidVisitor
{
public:
 
    void operator() (const ModelData::Part& thePart) override
    {
        auto aPartName = thePart.Name().IsEmpty() ? "noname" : thePart.Name();
 
            size_t aBodyNumber = 0;
            const auto& aBodies = thePart.Bodies();
            for (const auto& aBody : aBodies) {
                ModelData::ShapeIterator aShapeIt (aBody);
                while (aShapeIt.HasNext()) {
                    const auto& aShape = aShapeIt.Next();
                    if (aShape.Type() == ModelData::ShapeType::Solid) {
                        cout << "Part #" << myPartIndex << " [\"" << aPartName << "\"] - solid #" << std::to_string (aBodyNumber) << " has:" << endl;
                        ProcessSolid (ModelData::Solid::Cast (aShape));
                    } else if (aShape.Type() == ModelData::ShapeType::Shell) {
                        cout << "Part #" << myPartIndex << " [\"" << aPartName << "\"] - shell #" << std::to_string (aBodyNumber) << " has:" << endl;
                        ProcessShell (ModelData::Shell::Cast (aShape));
                    }
                }
                ++aBodyNumber;
            }
        ++myPartIndex;
    }
 
    virtual void ProcessSolid (const ModelData::Solid& theSolid) = 0;
 
    virtual void ProcessShell (const ModelData::Shell& theShell) = 0;
 
private:
    size_t  myPartIndex = 0;
};

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.

using namespace cadex;
 
class SolidProcessor : public ModelData::ModelElementVoidVisitor
{
public:
 
    void operator() (const ModelData::Part& thePart) override
    {
        auto aPartName = thePart.Name().IsEmpty() ? "noname" : thePart.Name();
 
        size_t aBodyNumber = 0;
        const auto& aBodies = thePart.Bodies();
        for (const auto& aBody : aBodies) {
            ModelData::ShapeIterator aShapeIt (aBody);
            while (aShapeIt.HasNext()) {
                const auto& aShape = aShapeIt.Next();
                if (aShape.Type() == ModelData::ShapeType::Solid) {
                    cout << "Part #" << myPartIndex << " [\"" << aPartName << "\"] - solid #" << std::to_string (aBodyNumber++) << " has:" << endl;
                    ProcessSolid (ModelData::Solid::Cast (aShape));
                }
            }
        }
 
        ++myPartIndex;
    }
 
    virtual void ProcessSolid (const ModelData::Solid& theSolid) = 0;
 
private:
    size_t  myPartIndex = 0;
};
