Revit二次开发之创建倾斜楼板（Create a slope floor / slab）

一、函数

链接: 官方文档地址.

/*使用给定的水平轮廓创建默认样式楼板。*/
public Floor NewSlab(
	CurveArray profile,//斜板水平投影轮廓
	Level level,//水平投影标高
	Line slopedArrow,//倾斜轴，即水平投影与斜边相交的边
	double slope,//倾斜角度
	bool isStructural//是否结构
)

二、图示

三、代码

 public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
         try {
             UIDocument uiDoc = commandData.Application.ActiveUIDocument;
             Document doc = uiDoc.Document;
             Selection sel = uiDoc.Selection;
             Autodesk.Revit.Creation.Application acreation = commandData.Application.Application.Create;
             Autodesk.Revit.Creation.Document dcreation = doc.Create;

             Transaction ts = new Transaction(doc, "www");
             ts.Start();

             
             double h = 7;//斜板较高一端与斜板较低一端的高度差
             double l = 5;//斜板水平投影长度
             double w = 10;//斜板水平投影宽度

             double x0 = 0;
             double y0 = 0;
             double z0 = 1;

             XYZ p_s0 = new XYZ(x0, y0, z0);
             XYZ p_s1 = new XYZ(x0, y0 + w, z0);
             XYZ p_s2 = new XYZ(x0 + l, y0 + w, z0);
             XYZ p_s3 = new XYZ(x0 + l, y0, z0);
             
             Line l_s0 = Line.CreateBound(p_s0, p_s1);
             Line l_s1 = Line.CreateBound(p_s1, p_s2);
             Line l_s2 = Line.CreateBound(p_s2, p_s3);
             Line l_s3 = Line.CreateBound(p_s3, p_s0);

             CurveArray fProfile = new CurveArray();
             fProfile.Append(l_s0);
             fProfile.Append(l_s1);
             fProfile.Append(l_s2);
             fProfile.Append(l_s3);

             var levelCollector = new FilteredElementCollector(doc).OfClass(typeof(Level));
             var slablevel = levelCollector.FirstOrDefault(e => e.Name == "斜板标高") as Level;
             if (slablevel == null) {
                 slablevel = Level.Create(doc, z0);
                 slablevel.Name = "斜板标高";
             } else slablevel.Elevation = z0;


            
             Line slopeLine = l_s0;//斜板与其投影面相交的线
             double slope = Math.Atan(h / w);//斜板的角度
             var slopeSlab = dcreation.NewSlab(fProfile, slablevel, slopeLine, slope, true);
             ts.Commit();

             return Result.Succeeded;
         } catch (Exception ex) {
             var r = 0;
             return Result.Succeeded;

         }
