python - 从折线获取曲线以创建细节线

Question

我正在尝试创建一个脚本，可以从选择中创建详细信息线。

虽然每条线大约有 5 英尺大，但脚本显示以下错误:

Exception : Autodesk.Revit.Exceptions.ArgumentsInconsistentException: Curve length is too small for Revit's tolerance (as identified by Application.ShortCurveTolerance) Parameter name: endpoints

我的代码是:

                line.append(Line.CreateBound(a,b))

Answer 1

四个嵌套的 for 循环将生成大量的行。我无法想象你真的需要所有这些。您可以添加一个断言，保证 a 和 b 之间的最小距离始终大于(例如，十分之一英寸)约。 2.5毫米。我敢打赌这个断言一定会火。换句话说，您的某些线路可能比 5 英尺短。也许有些长度甚至为零？
