Solved: Recurring problem when importing shapefile in C3D with Objects Data

m.chavet7MJRB · ‎10-24-2023

Hello,

I'm currently importing shapefiles via C# code into Civil3D with its attributes converted into FDO.

After a few imports, it happens that the file becomes "corrupted", i.e. I'm no longer authorized to import it with Objects Data.

If I remove the line that allows the attributes to be imported, the import works (like a normal Mapimport). The line of code is: "inputLayer.SetDataMapping(ImportDataMapping.NewObjectDataOnly, fileName);"

Here is my code :

[CommandMethod("AEPImportShape")]

public void AEPImportShape()
{
    Stopwatch sw = new Stopwatch();
    sw.Start();
    MapApplication mapApp = HostMapApplicationServices.Application;
    using (Importer importer = mapApp.Importer)
    {
      
        Autodesk.AutoCAD.Windows.OpenFileDialog ofd = new Autodesk.AutoCAD.Windows.OpenFileDialog("Select Shapefile", null, 
            "shp", "Select shp", Autodesk.AutoCAD.Windows.OpenFileDialog.OpenFileDialogFlags.AllowAnyExtension);
     
        if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {

            //Array.Sort(shpFiles);
            string shpFiles = ofd.GetFilenames()[0];
            importer.Init("SHP", shpFiles);

            string fileName = Path.GetFileNameWithoutExtension(shpFiles).Replace(" ", "");

            foreach (InputLayer inputLayer in importer)
            {
                inputLayer.SetLayerName(LayerNameType.LayerNameDirect, fileName);
                inputLayer.SetDataMapping(ImportDataMapping.NewObjectDataOnly, fileName);
                //inputLayer.Dispose();
            }

            importer.ImportPolygonsAsClosedPolylines = true;
            ImportResults result = importer.Import(true);
            sw.Stop();
            
            //importer.Dispose();
            dynamic acadApp = Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication;
            acadApp.ZoomExtents();
        }
        
    }

}

If I copy the shapefile, and retry the import, sometimes it works with the ODs. I repeated this manip several times.

Here is the error:

Application does not support just-in-time (JIT)
debugging. See the end of this message for details.

your code works ok for me, but i don't have much shp data to test. do you have a problem file you can share?

the error msg you posted indicates an error occurred at line 68 in Class1.cs - that does not match the code you posted.

have you tried a try{} catch{} structure to check for MapException?

Thank you for your answer

As I said, it's this line: inputLayer.SetDataMapping(ImportDataMapping.NewObjectDataOnly, fileName); ; when I import the Object Data.

I tried a lot of things to repair these data in QGIS but it still doesn't work. I generated again the entire layer, but it doesn't work. I tried with another point layer and it works.

You can download the data here: https://we.tl/t-KMt8pFRZuV

I got this Exception Thrown :

System.NullReferenceException: 'Object reference not set to an instance of an object.'

the problem is the length of "fname" - it's ok to create a layer name but too long for a table name.

SetLayerName(LayerNameType.LayerNameDirect, fname) // works
SetDataMapping(ImportDataMapping.NewObjectDataOnly, fname) // does not work

if you use OOTB "MapImport", you will see that autocad truncates the table name to 25 chars. QGIS does not.
