Export Feature Class to CAD

hafidismaili — Fri, 10 Dec 2021 20:53:43 GMT

I'm new in Arcobject, and I have to convert a selected features to CAD drawing using just arcobjects and c#.the code below work good when i convert to a shapefile "ShapeFileWorkspaceFactory" but with the "CadWorkspaceFactory" it doesn't work.

any help will be greatly appreciated

 

public void featureToCad(){



IFeatureLayer fl = search_layer2(axMapControl1.Map, "parcelle") as IFeatureLayer;


        IFeatureClass pFC;

        IFeatureClassName pInFeatureClassName;
        IDataset pDataset;
        IDatasetName pInDsName;
        IFeatureSelection pFSel;
        ISelectionSet pSelSet;
        IFeatureClassName pFeatureClassName;
        IDatasetName pOutDatasetName;
        IWorkspaceName pWorkspaceName;

        // *******************************
        // Get the featureclass from the layer
        // *******************************
        pFC = fl.FeatureClass;
        // ***********************************************
        // Get the Featureclassname from the featureclass
        // ***********************************************
        pDataset = pFC as IDataset;
        pInFeatureClassName = (IFeatureClassName)pDataset.FullName;
        pInDsName = (IDatasetName)pInFeatureClassName;
        // ***************************
        // Get the selected features
        // ***************************
        pFSel = fl as IFeatureSelection;
        pSelSet = pFSel.SelectionSet;
        IWorkspace pScratchWorkspace;
        IScratchWorkspaceFactory pScratchWorkspaceFactory;
        pScratchWorkspaceFactory = new ScratchWorkspaceFactory();
        pScratchWorkspace = pScratchWorkspaceFactory.DefaultScratchWorkspace;

        // ***************************************************
        // Define the output featureclass
       // give it the name of the input feature class + exp
      // ***************************************************
  pFeatureClassName = (IFeatureClassName)new FeatureClassName();
  pOutDatasetName = (IDatasetName)pFeatureClassName;
  pOutDatasetName.Name = (pFC.AliasName + "exp");
  pWorkspaceName = (IWorkspaceName)new WorkspaceName();
  pWorkspaceName.PathName = "D:\\";
  pWorkspaceName.WorkspaceFactoryProgID = "esriDataSourcesFile.CadWorkspaceFactory";//it works with "ShapeFileWorkspaceFacto"
  pOutDatasetName.WorkspaceName = pWorkspaceName;
  // *************************************************************
  // Give the output shapefile the same props as the input dataset
  // *************************************************************
  pFeatureClassName.FeatureType = pFC.FeatureType;
  pFeatureClassName.ShapeType = pFC.ShapeType;
  pFeatureClassName.ShapeFieldName = pFC.ShapeFieldName;
  // *************************************************************
  // Export selected features
  // *************************************************************
  pExportOp = new ExportOperation();
  pExportOp.ExportFeatureClass(pInDsName, null, pSelSet, null,pFeatureClassName,0);

I've moved your post into the ArcObjects SDK space. You will get a much better answer here as the GeoNet Help is intended for community help and feedback. You can see more on the community structure, and what topics are under each space from the following documents:
