Import

When reading a file, the result is converted into a common data model that provides format-neutral data representation and access API.

Reading files

ModelData::ModelReader is the primary class for reading files. The usage is simple: one just has to call a single function with the path to the file that should be read and the target ModelData::Model instance.

The data model object will be populated with the contents imported from the file being read. The model is not cleaned up before conversion, therefore multiple files can be accumulated in the same model.

#include <cadex/ModelData/ModelReader.hxx>
 
using namespace cadex;
 
ModelData::Model aModel;
ModelData::ModelReader aReader;
if (!aReader.Read ("myfile.stp", aModel)) {
    //error during reading the file
}

Parameters

Reader parameters are controlled by ModelData::ModelReaderParameters class and can be set using ModelData::ModelReader::SetParameters() method.

Parameter	Default value
ModelData::ModelReaderParameters::ReadPMI()	false
ModelData::ModelReaderParameters::ReadDrawing()	false
ModelData::ModelReaderParameters::EnableAnalyticalRecognition()	true

Export

To export a model, use the ModelData::ModelWriter class. This class writes the contents of the model to a file in the specified format.

using namespace cadex;
 
ModelData::Model aModel;
// Populate the model...
ModelData::ModelWriter aWriter;
 
if (!aWriter.Write(aModel, "output_model.mtk")) {
    std::cerr << std::endl << "ERROR: Failed to export " << std::endl;
}
