Change length of rebar type '77'

[sizy458]

Hello,

I should change the length of rebar 77 ,

how do i make ?

There is source code which multiply length by 1.1 and it dont' work.

  {
                Rebar rborg = TcmPick.saisiracier(uiapp.ActiveUIDocument, "ttt2");
                Document doc = rborg.Document;

                var hostid = rborg.GetHostId();
                var elthost = doc.GetElement(hostid) as FamilyInstance;

                Curve fromhost = null;

                XYZ p1pot = XYZ.Zero;
                var lc = elthost.Location;
                if (lc is LocationCurve)
                {
                    var clcc = lc as LocationCurve;
                    var ccc = clcc.Curve;
                    p1pot = ccc.GetEndPoint(0);
                    fromhost = clcc.Curve;
                }
                if (lc is LocationPoint)
                {
                    var lcp = lc as LocationPoint;
                    p1pot = lcp.Point;
                }
                //var p1 = lc.Point;
                double dx = Tcmconversionunity.smminpied(450);
                double dy = Tcmconversionunity.smminpied(600);
                //double dy
                //p1 = new XYZ(p1.X - dx, p1.Y - dy, p1.Z);

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

                RebarShapeDrivenAccessor da = rborg.GetShapeDrivenAccessor();
                Line l1 = da.GetDistributionPath();

                var lcc = da.ComputeDrivingCurves();
                XYZ sanormal = l1.Direction;//l1.GetEndPoint(1);//
                XYZ pn1 = l1.GetEndPoint(1);
                Curve cc = lcc[0];
                XYZ p1cc = cc.GetEndPoint(0);
                XYZ p2cc = cc.GetEndPoint(1);

                Arc aa = cc as Arc;

                XYZ p1c = aa.Center;


                

                XYZ sanormalarc = aa.Normal;
                XYZ sanormalarctrafiquer = sanormalarc;
               

                XYZ sanormalarcperpendiculaire = -1 * sanormalarctrafiquer.CrossProduct(new XYZ(0, 1, 0)); //s3

                Plane parc = Plane.CreateByNormalAndOrigin(sanormalarctrafiquer, XYZ.Zero);
                Plane pldbg = Plane.CreateByNormalAndOrigin(sanormalarcperpendiculaire, XYZ.Zero);
                Transform ftdbg = Transform.CreateReflection(pldbg);
                XYZ p1b9cdbg = XYZ.Zero;


                p1b9cdbg = ftdbg.OfPoint(new XYZ(0 - aa.Radius, 0 - aa.Radius, 0)); //S3

             

                p1b9cdbg = p1b9cdbg.Add(p1c);
                XYZ p1b9c = p1b9cdbg;



                double coefmultz = sanormal.Z >= 0 ? -1 : +1;

               

                da.ScaleToBoxFor3D(p1b9c, mvect(parc.XVec, aa.Radius * 2), mvect(parc.YVec, aa.Radius * 2), da.Height *1.1* 1.0 * coefmultz); //S2



                trans.Commit();
                trans = trans;
                return Result.Succeeded;
            }

Thank.

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

Your question is confusing.

What do you mean by 'length'?

You code multiplies the height by 1.1.

Please provide a minimal reproducible case for deeper analysis, including some screen snapshots illustrating the issue:

https://thebuildingcoder.typepad.com/blog/about-the-author.html#1b

We checked the ScaleToBoxFor3D function and it works correctly.

 
There are parts of your code that do not compile; “mvect” is an undefined function; two variables (double dx and dy) are not used. They are calculated using Tcmconversionunity.smminpied() which is another undefined function.

Thank you.

Best regards,

Jeremy

internal static XYZ mvect(XYZ p,double Radius)
        {
            return new XYZ(p.X * Radius, p.Y * Radius, p.Z * Radius);
        }

 internal static double smminpied(double val)
        {
            double v = val / 1000.0;
            v = Sminpied(v);
            return v;
        }


        internal static double Sminpied(double p)
        {
            return p / 0.3048;
        }

Please forget variable dx,dy
