使用 Python 的新 Floor.Create（） 方法 Revit 2023 API

问：

我目前正在通过pyRevit开发Revit插件，并且从Python中定义的三个顶点开始创建新的Revit三角形地板时遇到了一些麻烦。我是 Revit API 的新手，目前正在使用 Revit 2023。

我知道 API 与以前的版本相比有一些变化，例如新的 Floor.Create（） 方法。但是，当我运行代码时，我收到错误消息“ArgumentException：输入曲线循环无法组成有效边界，这意味着：”curveLoops“集合为空;或者一些曲线环相互相交;或者每个曲线环不是单独闭合的;或者每个曲线环都不是平面的;或每个曲线环不在平行于水平面（XY）的平面上;或输入曲线包含至少一条螺旋曲线。参数名称：Autodesk.Revit..DB.Floor.Create（文档文档、IList'1 配置文件、ElementId floorTypeId、ElementId levelId）“中的配置文件。

经过进一步检查，我检查了 CurveLoop（），一切似乎都井井有条（它是平面的、闭合的和逆时针的）。我将不胜感激在解决此问题方面的任何帮助。
