Our data is of pipelines and nodes wherein for each feature there is a line and a point node as end points.

So while copying parallel lines, we need to customize the OOTB tool so as to copy specific number of lines and create a node point at end of each line.

In general tool is working fine except for the scenario where it is a 'V' shaped feature i.e any angled feature.

I have attached the data before using our customised copy parallel and after using the tool.

I am working on ArcGIS 9.3.1 ESRI product.

    What is your purpose? creating point at the end of the line or both copy and create point? And Are you working with ILine or IPolyline? – Emi Feb 5 '13 at 6:22
  • Sorry forgot to mention. I am working on ArcGIS 9.3.1 ESRI product. I need to create a point feature for end vertices of each line. – Sheethal Feb 5 '13 at 6:26

If the layer is a feature layer, you can get IPolyline from each IFeature by IFeature.Shape Property.

IPolyline polyline = feature.Shape as IPolyline;
IPoint fromPoint = polyline.FromPoint;
IPoint toPoint = polyline.ToPoint;

Now create a point feature class and add these points as feature to that feature class.


I am guessing you are working with all features of your feature class. If that is not right, just change the search method as you need:

List<IFeature> GetAllFeatures(IFeatureClass ArcFeatureClass)
    var featureCursor = ArcFeatureClass.Search(null, false);
    var features = new List<IFeature>();
    Geodatabase.IFeature feature;
    while ((feature = featureCursor.NextFeature()) != null)
        features.Add(new Feature(feature));
    return features;

List<IPoint> GetEndPoints(List<IFeature> features)
    var points = new List<IPoint>();
    foreach(var feature in features)
        var polyline = feature.Shape as IPolyline;
    return points;

Now create a point feature class. Suppose, name of that feature class is 'pointFeatureClass'. If you need help to create feature class, you can go through this.

void AddFeatures(List<IPoint> points, IFeatureClass pointFeatureClass)
    if (pointFeatureClass == null)
    foreach (var point in points)
        IFeature feature = pointFeatureClass.CreateFeature();
        feature.Shape = point;


This code will put a point on each end of a polyline. For your figure, it will create 8 points. If you want to customize it, you can put your own logic.

  • Hi Emi, Thanks for your response. I have improved my question if you see I have attached screenshots of the problem. Please provide your suggestions for the same. – Sheethal Feb 7 '13 at 5:52
  • @Sheethal, Is there only one polyline and you break it in every turn? Or there are 4 polylines? – Emi Feb 7 '13 at 5:57
  • There are 4 polylines. – Sheethal Feb 7 '13 at 6:20
  • @Sheethal does this works for u? – Emi Feb 7 '13 at 12:27
  • I need to copy parallel lines to the selected features. – Sheethal Feb 8 '13 at 2:49
