BRepBuilderAPI_MakeWire 类可以返回添加到Wire上的最后一条边Edge 方法。如果复制了这条Edge则它可能与原始Edge不同。

Error 方法返回 BRepBuilderAPI_WireError 枚举中的一个术语WireDone – 没有发生错误。
EmptyWire – 未初始化算法使用了空构造函数。
DisconnectedWire – 最后添加的边未连接到Wire。
NonManifoldWire – 具有某种奇异性的Wire。 上述代码返回结果Wire failed-DisconnectedWire!
表明后面添加的边未连接到Wire也就是两个圆弧未连接线 通过以下代码输出圆弧的端点坐标发现圆弧之间的交点距离过大超出了容差将距离过大的用直线连接起来成功生成Wire。
