我已经创建了以下代码，并且一直坚持从元素中提取几何图形（在我的情况下，它将是 CAD 导入）
我期待这些解决方案：
- 如何在铁蟒中分类或过滤几何类型。
- 什么是索引器#
我真的不明白这一点，但我也试过这个..
选项 = Autodesk.Revit.DB.Options()
选定 = Ui.Selection.GetElementIds()
测试=（选择[0]）
CAD = doc.GetElement(测试)
曲线 = Cad.Geometry
打印（曲线）
NewCurve = doc.Create.NewDetailCurve(view,curves[options])
实际代码：
