Copy Parallel - Problem [closed]

Question

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.

Answer 1

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.

EDIT

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;
        points.Add(polyline.FromPoint);
        points.Add(polyline.ToPoint);
    }
    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)
        return;
    foreach (var point in points)
    {
        IFeature feature = pointFeatureClass.CreateFeature();
        feature.Shape = point;

        feature.Store();
    }
}

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.
