How to get the Object Points by Javascript

Anonymous — Fri, 18 Mar 2016 19:22:57 GMT

Hi,

I'm developing a javascript where once an Entity is selected (in my case, a Polyline), be able to get the vertex.

My App need to get for each Polyline selected, every 2D point in the shape and store such points in my DB.

Once I have the Entity selected and got it's ID, what function would hep me?

Is there any way to accomplish this task?

Hi,

Firstly I hope I got your point and secondly I hope you able to read C# codes to get the idea of the program and transfer them into Java.

Have a look;

var pl = (Polyline)trA.GetObject(s.ObjectId, OpenMode.ForRead);
 Point3dCollection lst = new Point3dCollection();
 int pts = (int)pl.GetParameterAtPoint(pl.EndPoint);
 ed.WriteMessage("\nNumber of params : " + (pts + 1).ToString());
 for (int i = 0; i < (pts + 1); i++)
 {
 lst.Add(pl.GetPointAtParameter(i));
 }
 foreach (Point3d p in lst)
 {
 ed.WriteMessage("\nPoint :" + p.ToString());
 }

Hi @_Tharwat,

Thanks for your quick answer.

Your solution step by creating a new DLL in .NET based on C# and within javascript call such function to be able to catch the points from the selected Entity?

Sorry I did not get your point and question.

Clarify it a bit more.

I believe he meant that your solution was to solve the problem in .NET and then call your solution from JavaScript.

I don't believe this is what you meant. I think you meant the original poster to look at your solution and translate it to JavaScript.
