Hide Level Heads and Elevation Markers

Hello,

I have been working on a Revit Addin and, so far, the end result is in the image bellow:

However, I want the Level Heads visible in the viewports to the left, the elevation markers and the axis arrows in the right-most viewport to not be visible. Bellow is parts of the code I have so far:

CreateView.cs (Creates views visible in the left-most viewports):

AddViewToSheetCommand.cs (Gets created views and Level 1 (default level), creates viewports and adds them to a sheet):

#region Namespaces using Autodesk.Revit.ApplicationServices; using Autodesk.Revit.Attributes; using Autodesk.Revit.DB; using Autodesk.Revit.DB.Structure; using Autodesk.Revit.UI; using Autodesk.Revit.UI.Selection; using System; using System.Collections; using System.Collections.Generic; using System.Diagnostics; using System.Linq; #endregion namespace RevitAddin { [Transaction(TransactionMode.Manual)] class AddViewToSheetCommand : IExternalCommand { public Result Execute( ExternalCommandData commandData, ref string message, ElementSet elements) { UIApplication uiapp = commandData.Application; UIDocument uidoc = uiapp.ActiveUIDocument; Application app = uiapp.Application; Document doc = uidoc.Document; // Filtered Element Collector list for the 3D Views FilteredElementCollector collector3DViews = new FilteredElementCollector(doc); collector3DViews.OfClass(typeof(View3D)); List<View3D> all3DViews = collector3DViews.Cast<View3D>().ToList(); // Filtered Element Collector for the Floor Plans FilteredElementCollector collectorFloorPlans = new FilteredElementCollector(doc); collectorFloorPlans.OfClass(typeof(ViewPlan)); List<ViewPlan> allViewPlans = collectorFloorPlans.Cast<ViewPlan>().ToList(); // Filtered Element Collector list for Sheet Views FilteredElementCollector collectorSheetViews = new FilteredElementCollector(doc); collectorSheetViews.OfClass(typeof(ViewSheet)); List<ViewSheet> allSheetViews = collectorSheetViews.Cast<ViewSheet>().ToList(); // Grab created Sheet View ViewSheet sheet = allSheetViews.LastOrDefault(); // Grab default level 1 floor plan ViewPlan level1 = allViewPlans.First(n => n.Name == "Level 1"); // Grab all created Views View3D v1 = all3DViews[all3DViews.Count - 3]; View3D v2 = all3DViews[all3DViews.Count - 2]; View3D v3 = all3DViews[all3DViews.Count - 1]; // Get ids of Project Points List<ElementId> basePointIds = new FilteredElementCollector(uidoc.Document, level1.Id) .WhereElementIsNotElementType() .OfClass(typeof(BasePoint)) .ToElementIds() .ToList(); // Get ids for the view's Elevation Markers points List<ElementId> viewElevationMarkerIds = new FilteredElementCollector(uidoc.Document, level1.Id) .WhereElementIsNotElementType() .OfClass(typeof(ElevationMarker)) .ToElementIds() .ToList(); // Modify document within a transaction using (Transaction tx3 = new Transaction(doc)) { tx3.Start("AddViewToSheet"); // Edit level1 to fit criteria level1.DetailLevel = ViewDetailLevel.Fine; level1.Scale = 300; if (basePointIds?.Count > 0) level1.HideElements(basePointIds); if (viewElevationMarkerIds?.Count > 0) level1.HideElements(viewElevationMarkerIds); // Set default viewport to "No Title" type ElementType elementType = new FilteredElementCollector(doc) .OfClass(typeof(ElementType)).Cast<ElementType>() .Where(x => x.Name == "No Title").First(); doc.SetDefaultElementTypeId(ElementTypeGroup.ViewportType, elementType.Id); // Add 4 viewports, 1 for each view Viewport viewport1 = Viewport.Create(doc, sheet.Id, v1.Id, new XYZ(0.45, 0.30, 0)); Viewport viewport2 = Viewport.Create(doc, sheet.Id, v2.Id, new XYZ(0.35, 0.85, 0)); Viewport viewport3 = Viewport.Create(doc, sheet.Id, v3.Id, new XYZ(0.45, 0.50, 0)); Viewport viewport4 = Viewport.Create(doc, sheet.Id, level1.Id, new XYZ(1, 0.40, 0)); tx3.Commit(); } return Result.Succeeded; } } }

What is missing here? I've been having this issue for a while so any feedback is appreciated.

Also, bellow is the test .rvt document and the .sln document for the addin.

Sorry for repeating myself hundreds of times over, but somehow I have become an anti-ToList fanatic.

You can save yourself some code and your computer some performance time and memory space by avoiding the calls to ToList for the base point and other ids. You may need to convert them from List to ICollection or something, but it will save (minimal) code, space and execution time.

I'm sorry this does not answer your question, though...

Hello Jeremy and thank you for your reply,

Although this does not answer my question, I appreciate the suggestion and I will figure out a way to not use .ToList so to save performance.

Thank you

I have figured the solutions for my issue and I'll leave the corrected code bellow:

CreateViewCommand.cs:

AddViewToSheetCommand.cs:

#region Namespaces using Autodesk.Revit.ApplicationServices; using Autodesk.Revit.Attributes; using Autodesk.Revit.DB; using Autodesk.Revit.DB.Structure; using Autodesk.Revit.UI; using Autodesk.Revit.UI.Selection; using System; using System.Collections; using System.Collections.Generic; using System.Diagnostics; using System.Linq; #endregion namespace RevitAddin { [Transaction(TransactionMode.Manual)] class AddViewToSheetCommand : IExternalCommand { public Result Execute( ExternalCommandData commandData, ref string message, ElementSet elements) { UIApplication uiapp = commandData.Application; UIDocument uidoc = uiapp.ActiveUIDocument; Application app = uiapp.Application; Document doc = uidoc.Document; // Filtered Element Collector list for the 3D Views FilteredElementCollector collector3DViews = new FilteredElementCollector(doc); collector3DViews.OfClass(typeof(View3D)); List<View3D> all3DViews = collector3DViews.Cast<View3D>().ToList(); // Filtered Element Collector for the Floor Plans FilteredElementCollector collectorFloorPlans = new FilteredElementCollector(doc); collectorFloorPlans.OfClass(typeof(ViewPlan)); List<ViewPlan> allViewPlans = collectorFloorPlans.Cast<ViewPlan>().ToList(); // Filtered Element Collector list for Sheet Views FilteredElementCollector collectorSheetViews = new FilteredElementCollector(doc); collectorSheetViews.OfClass(typeof(ViewSheet)); List<ViewSheet> allSheetViews = collectorSheetViews.Cast<ViewSheet>().ToList(); // Grab created Sheet View ViewSheet sheet = allSheetViews.LastOrDefault(); // Grab default level 1 floor plan ViewPlan level1 = allViewPlans.First(n => n.Name == "Level 1"); // Grab all created Views View3D v1 = all3DViews[all3DViews.Count - 3]; View3D v2 = all3DViews[all3DViews.Count - 2]; View3D v3 = all3DViews[all3DViews.Count - 1]; // Get id list of Project Points List<ElementId> basePointIds = new FilteredElementCollector(uidoc.Document, level1.Id) .WhereElementIsNotElementType() .OfClass(typeof(BasePoint)) .ToElementIds() .ToList(); // Get id list for the view's Elevation Markers points List<ElementId> viewElevationMarkerIds = new FilteredElementCollector(uidoc.Document, level1.Id) .WhereElementIsNotElementType() .OfClass(typeof(ElevationMarker)) .ToElementIds() .ToList(); // Get id list of the elements regarding the NSWE building sections on the level 1 view FilteredElementCollector viewerCollector = new FilteredElementCollector(doc, level1.Id) .OfCategory(BuiltInCategory.OST_Viewers); // Get building elevation Ids IEnumerable<ElementId> elemIds = from Element d in viewerCollector where doc.GetElement(d.GetTypeId()).Name.Equals("Building Elevation") select d.Id; // Create a list with the building elevation Ids ICollection<ElementId> hideMarksIds = elemIds.Cast<ElementId>().ToList(); // Get id list for axis arrow y on level1 view var internalOriginCollector = new FilteredElementCollector(doc, level1.Id) .OfClass(typeof(InternalOrigin)) .ToElementIds(); // Modify document within a transaction using (Transaction tx3 = new Transaction(doc)) { tx3.Start("AddViewToSheet"); // Edit level1 to fit criteria level1.DetailLevel = ViewDetailLevel.Fine; level1.Scale = 300; if (basePointIds?.Count > 0) level1.HideElements(basePointIds); if (viewElevationMarkerIds?.Count > 0) level1.HideElements(viewElevationMarkerIds); if (hideMarksIds?.Count > 0) level1.HideElements(hideMarksIds); if (internalOriginCollector?.Count > 0) level1.HideElements(internalOriginCollector); // Set default viewport to "No Title" type ElementType elementType = new FilteredElementCollector(doc) .OfClass(typeof(ElementType)).Cast<ElementType>() .Where(x => x.Name == "No Title").First(); doc.SetDefaultElementTypeId(ElementTypeGroup.ViewportType, elementType.Id); // Add 4 viewports, 1 for each view Viewport viewport1 = Viewport.Create(doc, sheet.Id, v1.Id, new XYZ(0.45, 0.25, 0)); Viewport viewport2 = Viewport.Create(doc, sheet.Id, v2.Id, new XYZ(0.45, 0.85, 0)); Viewport viewport3 = Viewport.Create(doc, sheet.Id, v3.Id, new XYZ(0.45, 0.55, 0)); Viewport viewport4 = Viewport.Create(doc, sheet.Id, level1.Id, new XYZ(1.10, 0.55, 0)); tx3.Commit(); } return Result.Succeeded; } } }

Thank you all!
