在revit用C#写的一键生成四面有墙、有地面、有屋面的小房子的代码

下面是一键生成四面有墙、有地面、有屋面的小房子的C#代码：

//获取当前文档
Document doc = uidoc.Document;
//获取当前文档的单位
DisplayUnitType unitType = doc.GetUnits().GetFormatOptions(UnitType.UT_Length).DisplayUnits;

//设置墙体参数
WallType wallType = new FilteredElementCollector(doc).OfClass(typeof(WallType)).First(x => x.Name == "Generic - 8\"").ToWallType();
Level level = new FilteredElementCollector(doc).OfClass(typeof(Level)).First(x => x.Name == "Level 1") as Level;
double height = 10 / UnitUtils.Convert(1, DisplayUnitType.DUT_FEET, unitType);
double thickness = 0.5 / UnitUtils.Convert(1, DisplayUnitType.DUT_INCHES, unitType);

//创建墙体
XYZ startPoint = new XYZ(0, 0, 0);
XYZ endPoint = new XYZ(10, 0, 0);
Line line = Line.CreateBound(startPoint, endPoint);
Wall wall1 = Wall.Create(doc, line, level.Id, false);
wall1.WallType = wallType;
wall1.get_Parameter(BuiltInParameter.WALL_HEIGHT_TYPE).Set(height);

startPoint = new XYZ(10, 0, 0);
endPoint = new XYZ(10, 10, 0);
line = Line.CreateBound(startPoint, endPoint);
Wall wall2 = Wall.Create(doc, line, level.Id, false);
wall2.WallType = wallType;
wall2.get_Parameter(BuiltInParameter.WALL_HEIGHT_TYPE).Set(height);

startPoint = new XYZ(10, 10, 0);
endPoint = new XYZ(0, 10, 0);
line = Line.CreateBound(startPoint, endPoint);
Wall wall3 = Wall.Create(doc, line, level.Id, false);
wall3.WallType = wallType;
wall3.get_Parameter(BuiltInParameter.WALL_HEIGHT_TYPE).Set(height);

startPoint = new XYZ(0, 10, 0);
endPoint = new XYZ(0, 0, 0);
line = Line.CreateBound(startPoint, endPoint);
Wall wall4 = Wall.Create(doc, line, level.Id, false);
wall4.WallType = wallType;
wall4.get_Parameter(BuiltInParameter.WALL_HEIGHT_TYPE).Set(height);

//设置地面参数
FloorType floorType = new FilteredElementCollector(doc).OfClass(typeof(FloorType)).First(x => x.Name == "Generic - 12\"").ToFloorType();
double floorHeight = 0 / UnitUtils.Convert(1, DisplayUnitType.DUT_FEET, unitType);

//创建地面
List<Curve> curves = new List<Curve>();
curves.Add(Line.CreateBound(new XYZ(0, 0, floorHeight), new XYZ(10, 0, floorHeight)));
curves.Add(Line.CreateBound(new XYZ(10, 0, floorHeight), new XYZ(10, 10, floorHeight)));
curves.Add(Line.CreateBound(new XYZ(10, 10, floorHeight), new XYZ(0, 10, floorHeight)));
curves.Add(Line.CreateBound(new XYZ(0, 10, floorHeight), new XYZ(0, 0, floorHeight)));
Floor floor = doc.Create.NewFloor(curves, floorType, level, false);

//设置屋顶参数
RoofType roofType = new FilteredElementCollector(doc).OfClass(typeof(RoofType)).First(x => x.Name == "Generic - 8\"").ToRoofType();
double roofHeight = 20 / UnitUtils.Convert(1, DisplayUnitType.DUT_FEET, unitType);

//创建屋顶
FootPrintRoof roof = FootPrintRoof.Create(doc, floor.GetBoundarySegments(new SpatialElementBoundaryOptions()), level.Id, roofType.Id);
roof.get_Parameter(BuiltInParameter.ROOF_CONSTRAINT_OFFSET).Set(roofHeight);

这段代码中，首先获取了当前文档以及单位，并设置了墙体、地面和屋顶的参数。然后，创建了四面有墙、有地面、有屋面的小房子。具体实现方式是通过创建墙体、地面和屋顶的曲线来实现的。其中，墙体由四条线段组成，地面和屋顶则由四条线段组成的闭合曲线组成。最后，将创建的墙体、地面和屋顶添加到文档中。
