需要对我的代码进行哪些更改才能在 Revit 中创建新的 3D 透视图？

Question

我从 The Building Coder 复制了一些代码以在已打开的 Revit 文件中创建 3D 透视图。但是，当我运行 Execute 方法绝对没有任何反应。输出日志中没有抛出异常或错误，所以我认为这只是我的代码副本的问题。

我需要做什么才能使此代码创建 3D 透视图and/or在 Revit 中打开它？

using (Transaction t = new Transaction(doc, "CameraTransaction"))
            {
                t.Start();
                IEnumerable<ViewFamilyType> viewFamilyTypes = from elem in new FilteredElementCollector(doc).OfClass(typeof(ViewFamilyType))
                                                              let type = elem as ViewFamilyType
                                                              where type.ViewFamily == ViewFamily.ThreeDimensional
                                                              select type;
                
                View3D issue3DCameraView = View3D.CreatePerspective(doc, viewFamilyTypes.First().Id);
                issue3DCameraView.Name = "Issue_" + issue.Name;

                PerspectiveCamera cam = issue.Viewpoints[i].PerspectiveCamera;
                XYZ position = new XYZ(cam.CameraViewPoint.X, cam.CameraViewPoint.Y, cam.CameraViewPoint.Z);
                XYZ up = new XYZ(cam.CameraUpVector.X, cam.CameraUpVector.Y, cam.CameraUpVector.Z);
                XYZ sightDir = new XYZ(cam.CameraDirection.X, cam.CameraDirection.Y, cam.CameraDirection.Z);

                var orientation = new ViewOrientation3D(position, up, sightDir);
                issue3DCameraView.SetOrientation(orientation);

                Parameter farClip = issue3DCameraView.LookupParameter("Far Clip Active");
                farClip.Set(0);

                Parameter cropRegionVisible = issue3DCameraView.LookupParameter("Crop Region Visible");
                cropRegionVisible.Set(1);

                Parameter cropView = issue3DCameraView.LookupParameter("Crop View");
                cropView.Set(1);
/* Removed                
//Added in an attempt to make the code work
                RevitCommandId commandId = RevitCommandId.LookupPostableCommandId(PostableCommand.Default3DView);
                if (app.CanPostCommand(commandId))
                {
                    app.PostCommand(commandId);
                }*/

                t.Commit();
            }

编辑：对该问题的进一步研究表明，交易只是停止在“issue3DCameraView.SetOrientation（方向）；”线.

Answer 1

我无法通过查看您的代码来判断可能有什么问题...当然，除了您添加的 PostCommand 调用。那肯定没用，反而是。

我建议您先研究 Creating and Setting Up a 3D View 上的建筑编码器主题组中列出的其他一些文章，而不是尝试为您修复代码。

Answer 2

此代码的问题在于 issue.Viewpoints[i].PerspectiveCamera 的源代码。代码本身工作正常。

我在这里留下这个答案是为了那些追随我的人。
