在 Revit 中更改线型后 api 无法在对象样式中找到新的线型

Question

我正在 Revit 族中创建一个类别，它是一种线型，在我设置它之后，它存在，但我在族中找不到它，但如果尝试重新创建它，revit 会创建一个错误，它已经存在.我尝试使用再生，但这不起作用。

ElementId solidLineId = LinePatternElement.GetSolidPatternId();

        // The new linestyle will be a subcategory of the Lines category        
        Categories categories = doc.Settings.Categories;
        Category lineCat = categories.get_Item(BuiltInCategory.OST_Lines);

        using (Transaction t = new Transaction(doc, "Create LineStyle"))
        {
            t.Start();
            Category newLineStyleCat = categories.NewSubcategory(lineCat, "Black-01-Solid");
            newLineStyleCat.SetLineWeight(1, GraphicsStyleType.Projection);
            newLineStyleCat.LineColor = new Color(28,28, 28);
            newLineStyleCat.SetLinePatternId(solidLineId, GraphicsStyleType.Projection);
            t.Commit();
        }

这就是创建新线型的方法

分类猫=famDoc.OwnerFamily.FamilyCategory； 类别 newSubCat = null;

        if (!cat.SubCategories.Contains(subCatToAdd))
        {
            using (Transaction t = new Transaction(famDoc, "Add new or find existing subcategory"))
            {
                t.Start();
                newSubCat = famDoc.Settings.Categories.NewSubcategory(cat, subCatToAdd);
                GraphicsStyleType gst = GraphicsStyleType.Projection;
                GraphicsStyle gs = newSubCat.GetGraphicsStyle(gst);
                newSubCat.SetLineWeight(lineWeight, gst);
                t.Commit();
            }
        }
