如何在套筒(专用设备)和网格线之间绘制尺寸

Question

我们想在套筒（专用设备）和网格线之间绘制尺寸。

但是当我们应用尺寸Revit时，会抛出错误消息"删除引用 - 突出显示尺寸的引用不再平行"

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);

错误

Answer 1

首先创建一个通过用户界面手动工作的尺寸，然后使用 RevitLookup 分析其属性并找出它选取的确切引用。通常，如果某个功能在 Revit 产品中无法通过用户界面手动使用，则 Revit API 也不会提供该功能。
