确定一点处于闭合曲线内还是闭合曲线外。
rhinoscriptsyntax.PointInPlanarClosedCurve (point, curve, plane=None, tolerance=None)
rhinoscript.curve.PointInPlanarClosedCurve (point, curve, plane=None, tolerance=None)
point |
必须参数。包含三个数字的列表或者 Point3d 对象。要计算的 3-D 点。 |
curve |
必须参数。字符串或 Guid。闭合平面曲线的 ID 。 |
plane |
可选参数。平面。闭合曲线及点所在的平面。如果省略，将使用当前启用的构造平面。 |
tolerance |
可选参数。数字。公差。如果省略，将使用当前文档的绝对公差。 |
数字 |
执行成功返回代表执行结果的数字。结果如下：

None |
如果执行不成功或出错，返回空值。 |
