给我一段revit生成柱子的C#代码

在Revit中，可以使用以下代码来生成柱子：Document doc = uidoc.Document;FamilySymbol columnSymbol = new FilteredElementCollector(doc) .OfClass(typeof(FamilySymbol)) .WhereElementIsElementType() .Cast<FamilySymbol>() .FirstOrDefault(s => s.Family.Name == "Column");// Create the columnLocationPoint point = new XYZ(0, 0, 0);Level level = new FilteredElementCollector(doc).OfClass(typeof(Level)).Cast<Level>().FirstOrDefault(l => l.Name == "Level 1");if (columnSymbol != null) {FamilyInstance column = doc.Create.NewFamilyInstance(point, columnSymbol, level, StructuralType.NonStructural);}
