How to create error red circles?

[jamalkhah]

Hi,

When we have errors while creating boundaries, the errors are displayed as a red circle. I wanted to know what kind of red circles are and how can I create them for other purposes?

            double size = 10;//this is the radius of the circle. Adjust as desired, or, better yet, make this a ratio of the current screen size.
            Circle circle = new Circle(pt, v3d, size);
            m_mrkers.Add(circle);
            circle.ColorIndex = color;
            aGi.TransientManager.CurrentTransientManager.AddTransient(circle, aGi.TransientDrawingMode.DirectShortTerm, 128, intColl);
        }

        private void showHighpoint(Point3d pt)
        {
            showCircle(pt, 2); //add a yellow circle
        }


        private void showLowpoint(Point3d pt)
        {
            showCircle(pt, 3); //add a green circle
        }

        private void removeMarkers()
        {
            //remove them all when we are done....don't want screen clutter!
            for (int i = 0; i < m_mrkers.Count; i++)
            {
                aGi.TransientManager.CurrentTransientManager.EraseTransient(m_mrkers[i], intColl);
                m_mrkers[i].Dispose();
            }
            m_mrkers.Clear();
        }

You can also register an event to the REGEN command which will call the RemoveMarkers().
