Rebar placement for Generic Model.

[shindeaa15]

Query: I am trying to place rebars for Generic Model, while placement I am facing below error. Can anyone please guide?

Error:  "host is not a valid rebar host.\r\n Parameter name: host"

Code: 

using (var txx = new Transaction(doc, "Distribution Bar for Wall"))

            {

                txx.Start();

                XYZ lst1 = new XYZ(lineSt.X - 1.0, lineSt.Y - 1.0, lineSt.Z - 2.0);

                XYZ est1 = new XYZ(lineEn.X - 1.0, lineEn.Y - 1.0, lineEn.Z + 2.0);

                double rebarQty = 10;

                double spacing = 0.5;

                List<RebarBarType> coll = new FilteredElementCollector(doc).OfClass(typeof(RebarBarType)).WhereElementIsElementType().Cast<RebarBarType>().ToList();

                RebarBarType barType = coll.First(x => x.Name == "D10"); //"D25 主筋2"

                double cover = 0.25;

                for (int i = 0; i < rebarQty; i++)

                {

                    XYZ lst = new XYZ(lineSt.X - spacing, lineSt.Y - 1.0, lineSt.Z - 2.0);

                    XYZ est = new XYZ(lineEn.X - spacing, lineEn.Y - 1.0, lineEn.Z + 2.0);

                    List<Curve> distBarCurve = new List<Curve> { Line.CreateBound(lst, est) as Curve };

                    Rebar distBars = Rebar.CreateFromCurves(doc, RebarStyle.Standard, barType, null, null, oEle, newNormal, distBarCurve, RebarHookOrientation.Left, RebarHookOrientation.Right, true, true);

                    distBars.GetShapeDrivenAccessor().SetLayoutAsFixedNumber(1, cover, true, true, true);

                    spacing += 0.5;

                }

                txx.Commit();

            }

Note: Here I am passing below element as host.

Reference selectEntity = uiDoc.Selection.PickObject(Autodesk.Revit.UI.Selection.ObjectType.Element, "Select a Haunch");
Element oEle= document.GetElement(selectEntity);

Can you place rebar in that host manually using the end user interface? If no, it will not be possible programmatically either.

I have tried to place rebars manually, but unable to select the Host. Please find the attached model.

Please Let me know if different steps needs to be followed to achieve Rebar placement for attached model.

Thank you in advance for addressing issue.

Please solve this issue manually in the end user interface first, before starting to think about an API solution. The API will not enable anything that the UI cannot. The best place to discuss it might be in the structural forum.

Okay

Thank you...
