Creating a model file entity and exporting it to a physical file

This section describes how to initiate the process of creating a model file and how to export that data to a physical file.

Create a file that contains the PRC data

  1. Create a pointer that references a populated model file entity. (See Create a model file entity.) In the following example, createModelFile is a private function that returns a pointer to a populated model file.
    A3DAsmModelFile* pModelFile = createModelFile();
  2. Create the model file entity. (See Create a model file entity.)
  3. Save the contents of the model file to a physical file by invoking the A3DAsmModelFileWriteToFile function.
    if (p != NULL) {
    	if (_access(pcPRCName, 00) != -1) 
    _unlink(pcPRCName);
    	A3DInt32 iRet = A3DAsmModelFileWriteToFile(p, NULL, pcPRCName);
  4. Delete the model file populated in Step 1.
    A3DAsmModelFileDelete(pModelFile);

NOTE: The Exchange API functions in this chapter are described as though implicit linking were possible. Wherever you see a direct call to one of these functions, you should instead use the pointer to the function. See Implementing external linking.
