app->SaveAs(doc, "exemple.caf") : No file resulting

Try adding path prefix to your file name, like "./exemple.caf". It should work.

Hi Bearloga
thanks for help but No result :(

some suggestions :

add the two following parameters in you "env.bat" file :
set CSF_ResourceVerbose
set CSF_ResourceDebug

It can help you to find the problem in your "message log".
The most popular problems are:
a wrong path for you file
a denied access to the specified directory

Here an example. It runs on my computer :
Standard_Integer SaveAs (Draw_Interpretor& di, Standard_Integer argc, char** argv)
{
TCollection_ExtendedString NomFichierTolerancement;

TCollection_ExtendedString Tfichier(argv[1]);

Handle(TDocStd_Application) Dessin= MecanismeIppopXDE::GetMecanismeIppopXDEApplication();
Handle(TDocStd_Document) DocShapeTolerancement= MecanismeIppopXDE::GetTDocStdDocumentTolerancement();

NomFichierTolerancement= TPath;

NomFichierTolerancement= NomFichierTolerancement+Tfichier;

NomFichierTolerancement= NomFichierTolerancement+TextTolerancement;

cout<<"NomFichierTolerancement : "<SaveAs(DocShapeTolerancement, NomFichierTolerancement);
if (theStatus != CDF_SS_OK )
{
switch ( theStatus ) {
case CDF_SS_DriverFailure: {
cout << " could not store , no driver found to make it " <
