Calculate Points and Values(포인트와 값 계산)

Get angle from X-axis
(angle)


using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.Geometry;

[CommandMethod("AngleFromXAxis")]
public static void AngleFromXAxis()
{
  Point2d pt1 = new Point2d(2, 5);
  Point2d pt2 = new Point2d(5, 2);

  Application.ShowAlertDialog("Angle from XAxis: " +
                              pt1.GetVectorTo(pt2).Angle.ToString());
}


Calculate Polar Point
(polar)

using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.Geometry;

static Point2d PolarPoints(Point2d pPt, double dAng, double dDist)
{
  return new Point2d(pPt.X + dDist * Math.Cos(dAng),
                     pPt.Y + dDist * Math.Sin(dAng));
}

static Point3d PolarPoints(Point3d pPt, double dAng, double dDist)
{
  return new Point3d(pPt.X + dDist * Math.Cos(dAng),
                     pPt.Y + dDist * Math.Sin(dAng),
                     pPt.Z);
}

[CommandMethod("PolarPoints")]
public static void PolarPoints()
{
  Point2d pt1 = PolarPoints(new Point2d(5, 2), 0.785398, 12);

  Application.ShowAlertDialog("\nPolarPoint: " +
                              "\nX = " + pt1.X +
                              "\nY = " + pt1.Y);

  Point3d pt2 = PolarPoints(new Point3d(5, 2, 0), 0.785398, 12);

  Application.ShowAlertDialog("\nPolarPoint: " +
                              "\nX = " + pt2.X +
                              "\nY = " + pt2.Y +
                              "\nZ = " + pt2.Z);
}

Find the distance between two points with the GetDistance method
(distance)


using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Runtime;

[CommandMethod("GetDistanceBetweenTwoPoints")]
public static void GetDistanceBetweenTwoPoints()
{
  Document acDoc = Application.DocumentManager.MdiActiveDocument;

  PromptDoubleResult pDblRes;
  pDblRes = acDoc.Editor.GetDistance("\nPick two points: ");

  Application.ShowAlertDialog("\nDistance between points: " +
                              pDblRes.Value.ToString());
}
