确定由两个共面的简单闭合曲线围成区域的关系。
rhinoscriptsyntax.PlanarClosedCurveContainment (curve_a, curve_b, plane=None, tolerance=None)
rhinoscript.curve.PlanarClosedCurveContainment (curve_a, curve_b, plane=None, tolerance=None)
curve_a |
必须参数。字符串或 Guid。第一个闭合平面曲线的 ID 。 |
curve_b |
必须参数。字符串或 Guid。第二个闭合平面曲线的 ID 。 |
plane |
可选参数。新的构造平面。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 |
执行成功返回表示相互关系的数字。结果如下：
