How to use SetSystemVariable setting coordinate values

[danielsu2013]

Hi,

I have a problem setting sysvar like SNAPBASE, which requires 2d point or 3d point.

I always get wrong input for the following lines. can anybody help to take a look?

 double[] point = new double[2] {5,5};
            
            object value1 = point;
            Application.SetSystemVariable("SNAPBASE", value1);

what value should I give a 2d point or 3d point?

Please help.

The value of system varibale SNAPBASE in .NET API is a Point2d, not a Point3d, nor a double array.

This code works:

        [CommandMethod("SetSB")]
        public static void SetSnapBase()
        {
            Document dwg = Application.DocumentManager.MdiActiveDocument;
            Editor ed = dwg.Editor;

            Point2d sBase = (Point2d)Application.GetSystemVariable("SNAPBASE");
            ed.WriteMessage("SNAPBASE: X={0} Y={1}", sBase.X, sBase.Y);

            Point2d newBase = new Point2d(2.0, 2.0);
            Application.SetSystemVariable("SNAPBASE", newBase);
            ed.WriteMessage("SNAPBASE: X={0} Y={1}", sBase.X, sBase.Y);
        }

thanks very much.

it worked well though there's a typo at the last line that should be newbase.

ed.WriteMessage("SNAPBASE: X={0} Y={1}", sBase.X, sBase.Y);
