[求助]Polyline.AddVertexAt()中Entity Coordinate System of the polyline是怎么确
[求助]Polyline.AddVertexAt()中Entity Coordinate System of the polyline是怎么确定的?我在增加polyline对象的角点的时候,遇到了这个问题。public void AddVertexAt(
int index,
Point2d pt,
double bulge,
double startWidth,
double endWidth
);
pt must be specified in the Entity Coordinate System of the polyline, not in the World Coordinate System (WCS).
其中我的polyline对象是在xoz平面上的,其Entity Coordinate System理所当然就是xoz平面,但其Entity Coordinate System的坐标圆点应该怎么确定呢?
望指点。
ECS,即对象坐标系,三维点使用pl.GetPlane()获取pl所在平面转换为二维点
Plane plane = pl.GetPlane();
Point3d pnt = new Point3d();
Point2d p2d = pnt.Convert2d(plane);
