Issue with creating Arc

JAYAKUMARKUMAR

Hi,

 

I have faced the issue to build Arc while using LineBuilderEx class. Could you please suggest which method I have to use to create Arc.

Hi @JAYAKUMARKUMAR ,

For building Arc in ArcGIS pro .net SDK, you can use EllipticArcBuilderEx or CircularArcBuilderEx depending on your requirements.
Following is the sample code to handle arcs

switch (segmentType)
{
    case SegmentType.EllipticArc:
        var ellipticArcSegment = segment as EllipticArcSegment;
        var ellipticArcBuilder = new EllipticArcBuilderEx(startPoint, endPoint, ellipticArcSegment.CenterPoint, 
            ellipticArcSegment.IsCounterClockwise ? ArcOrientation.ArcCounterClockwise : ArcOrientation.ArcClockwise);
        var newEllipticArcSegment = ellipticArcBuilder.ToSegment();
        polylineBuilder.ReplaceSegment(i, j, newEllipticArcSegment);
        arcflag = true;
        break;

    case SegmentType.CircularArc:
        var circularArcBuilder = new CircularArcBuilderEx(startPoint, endPoint, segment.Length);
        var newCircularArcSegment = circularArcBuilder.ToSegment();
        polylineBuilder.ReplaceSegment(i, j, newCircularArcSegment);
        arcflag = true;
        break;

    default:
        // Handle other segment types (e.g., lines, cubic Beziers)
        break;
}
