Copy a rebar shape 77

[sizy458]

Hello ,

this code for remove and recreate rebar work but

it's don't work with rebarshape '77'

I should delete and recreate entity of rebarshape '77'

Code:

public Result Commande5(
       UIApplication uiapp, object model)
        {
            
            {

                var rborg = TcmPick.saisiracier(uiapp.ActiveUIDocument, "ttt2"); ///Work !
                Document doc = rborg.Document;

                Transaction trans;
                trans = new Transaction(doc);
                trans.Start("delrebar");

                var cx = HelperRevit1.RevitHelper_GetComputeDriving(rborg).ToList();
                var normal = HelperRevit1.HelperRevit_GetNormalRebar(rborg);
                var shapeid = HelperRevit1.HelperRevit_GetShapeID(rborg);
                var rbshape = doc.GetElement(shapeid) as RebarShape;
               

                var start = rborg.GetHookTypeId(0);
                var end = rborg.GetHookTypeId(1);
                RebarHookType startHook = null, endHook = null;
                if (start != null)
                    startHook = doc.GetElement(start) as RebarHookType;
                if (end != null)
                    endHook = doc.GetElement(end) as RebarHookType;
                var startHookOrient = rborg.GetHookOrientation(0);
                var endHookOrient = rborg.GetHookOrientation(1);

                var rbbtype = doc.GetElement(rborg.GetTypeId()) as RebarBarType;

                ElementId hostId = rborg.GetHostId();
                doc.Delete(rborg.Id);
                trans.Commit();


                trans = new Transaction(doc);
                trans.Start("addrebar");
                var host = doc.GetElement(hostId);

                var rbdst = Rebar.CreateFromCurvesAndShape(doc, rbshape, rbbtype, startHook, endHook, host, normal, cx, startHookOrient, endHookOrient);
               
                //rbdst.RebarShapeId = shape77.Id;
                trans.Commit();
                // testinternet(uiapp, model);
                return Result.Succeeded;
            }


 internal static IList<Curve> RevitHelper_GetComputeDriving(Rebar rb)
        {
#if v2019
            RebarShapeDrivenAccessor rbaccessor;
            rbaccessor=rb.GetShapeDrivenAccessor();
#endif
#if v2019
            return rbaccessor.ComputeDrivingCurves();
#else
            return rb.ComputeDrivingCurves();
#endif         
        }

 internal static XYZ HelperRevit_GetNormalRebar(Rebar rb)
        {
#if v2019
            RebarShapeDrivenAccessor rbaccessor;
            rbaccessor=rb.GetShapeDrivenAccessor();
            return rbaccessor.Normal;
#else
            return rb.Normal;
#endif

        }

   internal static ElementId HelperRevit_GetShapeID(Rebar rb)
        {
#if v2019
           return rb.GetShapeId();
#else
            return rb.RebarShapeId;
#endif
        }

Dear Sizy,

Sorry, that nobody has been able to help you so far. I don't know either, so I passed on your query to the Revit Structural development team. 

Best regards,

Jeremy

Please provide a complete minimal reproducible case for deeper analysis:

Rebar shape 77 looks like a spiral which means it is a 3d shape. The method  Rebar.CreateFromCurvesAndShape works only with planar curves. This means that the 3d rebars can’t be created with this method.  You should use Rebar.CreateFromRebarShape for that. We also have a sample which does this, c.f. the NewRebar folder  and search for RebarShapeDefinitionByArcType.Spiral.

Best regards,

Jeremy
