TranslateCoordinates 方法 （ActiveX）
将点从一个坐标系转换为另一个坐标系。 支持的平台：仅限 Windows 签名VBA： RetVal = object.TranslateCoordinates(Point, FromCoordSystem, ToCoordSystem, Displacement, [OCSNormal])
返回值 （RetVal）类型：变体（双打的三元素阵列） 转换后的 3D 坐标。 言论不能直接将坐标从一个 OCS 转换为另一个 OCS。为此，首先将坐标从一个 OCS 转换为中间坐标系，例如 WCS。然后将该坐标转换为第二个 OCS。 要将 or 对象上的点从 OCS 转换为 WCS，请执行以下操作：PolylineLWPolyline
