Draw Dimension using Revit API

We want to draw dimensions between sleeve (specialty equipment) and Grid lines .

but when we apply dimensions revit throw the error message "Remove References - The references of highlighted dimension are no longer parallel"

How do you create this dimensioning in the UI? The API normally only supports stuff that the UI also supports.

First get Sleeve(speciality equipment) XYZ Co-ordinates
Second we get grid intersection point nearest to sleeve and then find nearest point from sleeve on the grid
Third step we get references of sleeve and grid.
Fourth one is draw line using sleeve and grid XYZ coordinates
and then draw dimensions

 XYZ sleeve_xyz = null;
                        Element elm = doc.GetElement(Sleeve_id.Id);
                        FamilyInstance fi = elm as FamilyInstance;
                        Autodesk.Revit.DB.Location position = elm.Location;
                        Autodesk.Revit.DB.LocationPoint positionPoint = position as Autodesk.Revit.DB.LocationPoint;
                        sleeve_xyz = positionPoint.Point;
                        sleeve_xyz = new XYZ(sleeve_xyz.X, sleeve_xyz.Y, 0);
                        Reference sleeve_ref = GetSleeveReference(fi, SpecialReferenceType.CenterLR);
                        Grid first_grid2 = doc.GetElement(First_Grid_elemID) as Grid;
                        Reference gridRef = null;
                        Options opt = new Options();
                        opt.ComputeReferences = true;
                        opt.IncludeNonVisibleObjects = true;
                        opt.View = doc.ActiveView;
                        foreach (GeometryObject obj in first_grid2.get_Geometry(opt))
                        {
                            if (obj is Autodesk.Revit.DB.Line)
                            {
                                Autodesk.Revit.DB.Line line = obj as Autodesk.Revit.DB.Line;
                                gridRef = line.Reference;
                            }
                        }
                        XYZ gr_point2 = new XYZ(grid_intersection_point.X, sleeve_xyz.Y, 0.000000000);
                        Autodesk.Revit.DB.Line line5 = null;
                        line5 = Autodesk.Revit.DB.Line.CreateBound(gr_point2, sleeve_xyz);
                        ReferenceArray refArray = new ReferenceArray();
                        refArray.Append(sleeve_ref);
                        refArray.Append(gridRef);
                        Dimension dim = doc.Create.NewDimension(doc.ActiveView, line5, refArray);
