Revit API - 新墙类型 - 如何排列图层？

Question

我正致力于通过 Revit 从头开始​​创建新的墙类型 API 我已经走得很远了（在我看来）但是我还有最后一个问题要解决。

如何按照我想要的方式排列墙的图层？这堵墙是用核心边界内的所有层创建的，这显然不理想。我正在尝试将 Finish 1 和 Finish 2 层放在核心边界两侧的外侧

感谢任何帮助。

我的墙是这样创建的：

这是我一直在查看但没有找到任何显示如何重新排列图层的资源。

https://thebuildingcoder.typepad.com/blog/2012/03/updating-wall-compound-layer-structure.html <-- 可能是最有用的 但我没有找到 "setlayerIndex" 命令

下面是我的代码： 代码

using (Transaction tx = new Transaction(doc))
            {
                tx.Start("ButtonName");
                newWallType = firstWallType.Duplicate("New Wall") as WallType;
                ElementId oldLayerMaterialId = firstWallType.GetCompoundStructure().GetLayers()[0].MaterialId;
                MaterialFunctionAssignment oldLayerFunction = firstWallType.GetCompoundStructure().GetLayers()[0].Function;
                MaterialFunctionAssignment newLayerFuncion = MaterialFunctionAssignment.Finish1;
                Debug.Print("newLayerFuncion: " + newLayerFuncion)


                CompoundStructureLayer newLayer = new CompoundStructureLayer(.25, newLayerFuncion, oldLayerMaterialId);
                CompoundStructureLayer newLayer2 = new CompoundStructureLayer(.5, MaterialFunctionAssignment.Finish2, oldLayerMaterialId);

                CompoundStructure structure = newWallType.GetCompoundStructure();

                IList<CompoundStructureLayer> layers = structure.GetLayers();


                layers.Add(newLayer);
                layers.Add(newLayer2);
                structure.SetLayers(layers);

                newWallType.SetCompoundStructure(structure);

                tx.Commit();
            }

            return Result.Succeeded;
        }

Answer 1

请阅读 CompoundStructureLayer and its members 上的标准 Revit API 文档。可能不需要 setlayerIndex 或其他方法来实现您的需要。

Answer 2

辛苦了，好好睡一觉，重读jeremey's link

我只需要在 structure.SetLayers(layers);

之后的正确位置添加 structure.SetNumberOfShellLayers(ShellLayerType.Exterior, 1);
