Rotate UCS about 90angle counterclockwise and zoom.

[Anonymous]

Hello,

I have this code:

Matrix3d cur = ed.CurrentUserCoordinateSystem;

                        Vector3d x = new Vector3d(1, 0, 0);
                        Vector3d y = new Vector3d(0, 1, 0);
                        Point3d o = new Point3d(0, 0, 0);
                        if (cur.CoordinateSystem3d.Xaxis == x & cur.CoordinateSystem3d.Yaxis == y & cur.CoordinateSystem3d.Origin == o)
                        {
                            Point3d center = (Point3d)Application.GetSystemVariable("VIEWCTR");
                            double viewsize = (double)Application.GetSystemVariable("VIEWSIZE");
                            Matrix3d newUcsMat = Matrix3d.AlignCoordinateSystem(new Point3d(0, 0, 0), new Vector3d(1, 0, 0), new Vector3d(0, 1, 0), new Vector3d(0, 0, 1),
                                new Point3d(0, 0, 0), new Vector3d(0, 1, 0), new Vector3d(-1, 0, 0), new Vector3d(0, 0, 1));
                            ed.CurrentUserCoordinateSystem = newUcsMat;
                            Utilities.Command("PLAN", "C");
                            Utilities.Command("ZOOM", "C", center.TransformBy(ed.CurrentUserCoordinateSystem), viewsize);

 Code is rotating well my model, but it's zooming to bad point.

I want to zoom to the point from previous view, so I'm transforming it by new UCS - unfortunately something is going wrong (it's not this point what I want).

Can anyone help me?

Sorry for the delay.

If you continue have this issue, can you please share a drawing and a sample project to demonstrate the issue.

Also, an explanation of the point to which you are trying to zoom-in would help.
