Hi every body,
I have a polyline, I want to automatic dimension if linesegment <18m and then add multileader to this linesegment as the picture below.
I can make dimension, but I dont know how to add multileader inside polyline. So, can any body help me to solve it?
My code is:
public static void GetLineSegment(Polyline pline)

acad.Document doc = acad.Application.DocumentManager.MdiActiveDocument;
Database db = doc.Database;
Editor ed = doc.Editor;
using (Transaction _tr = db.TransactionManager.StartTransaction())

if (pline.Closed == true)
{
var nbSegments = pline.NumberOfVertices;
for (int i = 1; i < nbSegments - 2; i++)
{
if (pline.GetSegmentType(i) == SegmentType.Line)
{
var line = pline.GetLineSegmentAt(i);
if (line.Length < 18)
{
var line1 = pline.GetLineSegmentAt(i - 1);
var line2 = pline.GetLineSegmentAt(i + 1);
Polyline pl1 = new Polyline();
pl1.AddVertexAt(0, new Point2d(line1.StartPoint.X, line1.StartPoint.Y), 0, 0, 0);

pl2.AddVertexAt(0, new Point2d(line2.EndPoint.X, line2.EndPoint.Y), 0, 0, 0);
Point3dCollection point3DCollection = new Point3dCollection();
pl1.IntersectWith(pl2, Intersect.ExtendBoth, point3DCollection, IntPtr.Zero, IntPtr.Zero);
foreach (Point3d pt in point3DCollection)
