Error Occurred when Calling Export to CAD Tool in ArcObjects

MatsHardy — Thu, 02 Dec 2021 06:33:21 GMT

I have developed a program to call the "Export To CAD" geoprocessing tool to export the feature classes in personal geodatabase to AutoCAD DWG files. Below are the codes:

private static void ExportToCADByGP(string mdbPath, string fcs, string outputType, string outputFile, string ignorePathsInTables = "Use_Filenames_in_Tables", string appendToExistingFiles = "Overwrite_Existing_Files", string seedFile = "")
{
int i;
IGeoProcessor gp = null;
IGPUtilities gpUtils;
IVariantArray parameters;
StringBuilder gpMsg;

try
{
gp = new GeoProcessor();
gp.SetEnvironmentValue("workspace", mdbPath);
parameters = new VarArray();
parameters.Add(fcs);
parameters.Add(outputType);
parameters.Add(outputFile);
if (string.IsNullOrEmpty(ignorePathsInTables))
{
parameters.Add(ignorePathsInTables);
parameters.Add(appendToExistingFiles);
parameters.Add(seedFile);
}

gp.Execute("ExportCAD_conversion", parameters, null);
parameters.RemoveAll();
gp.ClearMessages();
gpUtils = new GPUtilities();
gpUtils.ReleaseInternals();

Marshal.ReleaseComObject(parameters);
Marshal.ReleaseComObject(gpUtils);
}
catch (Exception ex)
{
if (gp == null)
{
Logger.Debug("ExportCAD: " + ex.Message);
}
else
{
gpMsg = new StringBuilder("Error running Export to CAD\r\n");
for (i = 0; i < gp.MessageCount; i++)
gpMsg.AppendLine(gp.GetMessage(i));
Logger.Debug("ExportCAD: " + gpMsg.ToString());
}
}
}

But when I ran the problem, the exception below occurred occasionally:

Failed to execute (ExportCAD).
Failed at Thu Dec 2 10:03:57 2021 (Elapsed Time: 8.81 seconds)

But after I ran the program repeatedly several times. DWG files can be exported without error.

Anyone has ideas where the problem is?

Did you ever figure out what was happening here? I have a few scripts that fail with the same error but not consistently. They run with a batch that all share the same structure. The largest two are the ones that fail. It almost seems like something times out or a memory allotment is exceeded but, again not consistently.
