Change Polyline3d

Anonymous — Fri, 19 Jul 2013 12:44:15 GMT

Hi,

i have a program to change the polyline3d. Something like

try
{
  using (tr)
  {
    Polyline3d poly3d = (Polyline3d)tr.GetObject(oid, OpenMode.ForWrite);
    ObjectId[] verts = poly3d.Cast<ObjectId>().ToArray();

    for (int i = 0; i < verts.Length; i++)
    {
      vt = tr.GetObject(verts[i], OpenMode.ForWrite) as PolylineVertex3d;
      vt.Position = new Point3d(X, Y, Z);
    }

    tr.Commit();
  }
}
catch
{
}
finally
{
tr.Dispose();
}

After that, the polyline3d changes perfectly. On the screen i can see the change. But when i run the command 3dorbit, then i see the polyline3d before the change.

You can see it on the Pictures

When i save the drawing and open it again, everthing is all right.

Can anyone tell me where the error is? 🙂

Thanks

Remove:
tr.Dispose();
from your code,
me think it's a reason of your problem
you don't need todispose objects, within USING{} code block

Hi,

thanks for the help. Unfortunately this does not work. I remove tr.Dispose(), then i try this

using (tr)
{
  try
  {
  }
}
catch
{
}
finally
{
tr.Dispose();
}

without success.

It is interesting, that the problem comes after the second (and each next) call to 3dorbit command. When I change polyline3d and then call to 3dorbit for the first time, everthing is fine. It is a little bit confusing.

We need to see the whole function in order to diagnose the prolem.
