SurfacePoints

返回曲面物件的控制点或控制顶点。

rhinoscriptsyntax.SurfacePoints (surface_id, return_all=True)

rhinoscript.surface.SurfacePoints (surface_id, return_all=True)

surface_id	必须参数。字符串或 Guid。物件的 ID 。
return_all	可选参数。布尔值。如果为 True（默认值），返回曲面所有的编辑点。如果为 False，函数将基于曲面是否闭合以及是否为周期曲面而返回编辑点。

列表	执行成功，返回曲面的控制点。
None	如果执行不成功或出错，返回空值。
