点的各种坐标系之间的转换

mkhsj928

以前一直用DLL导入acedTrans函数，其实在AutoCAD命名空间中有个Utility类就有TranslateCoordinates函数.

using AutoCAD;
using Autodesk.AutoCAD.Geometry;


public static Point3d TranslateCoordinate(this Point3d pt, AcCoordinateSystem from, AcCoordinateSystem to)
{
            AcadDocument acadDoc = Autodesk.AutoCAD.ApplicationServices.Core.Application.DocumentManager.MdiActiveDocument.GetAcadDocument() as AcadDocument;
            return new Point3d((double[])acadDoc.Utility.TranslateCoordinates(pt.ToArray(), from, to, 0));
}

1.

你有种再说一遍

调用方法?矩阵变换手写都可以啦

point3d有TransformBy方法，另外请不要在net区发com
