Overview

The Export Example shows how to export model data from ModelData_Model object to different file formats.

In this example we create a Writer which allows us to write data to a specific file format. It essentially mirrors the Importing Example.

Main Function

At the moment CAD Exchanger SDK supports a big variety of model types. Here we will export model data from ModelData_Model object to OBJ file format as one of the most popular one. Similar to the Import Example our main function will have the following structure:

Load a model data from XML file with ModelData_ModelReader:

ModelData_Model aModel;
 
if (!ModelData_ModelReader().Read (aSource, aModel)) {
    cerr << "Failed to read the file " << aSource << endl;
    return 1;
}

Create a OBJ_Writer and set some parameters:

OBJ_Writer aWriter;
OBJ_WriterParameters& aWriterParams = aWriter.Parameters();
 
aWriterParams.LengthUnit()        = Base_LengthUnit::Base_LU_Centimeters;
aWriterParams.ToGenerateMtlFile() = true;

Finally we can convert model data to a chosen format and save it:

if (!aWriter.Transfer (aModel)) {
    cerr << "Failed to transfer model data to specified format" << endl;
    return 1;
}
 
if (!aWriter.WriteFile (aDest)) {
    cerr << "Failed to write the file " << aDest << endl;
    return 1;
}

Summary

CAD Exchanger SDK provides a lot of packages for model data conversion. It's possible to read, write and transfer almost every existing model data format simply using algorithm described above.
