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):

public Result Execute(
ExternalCommandData commandData1,
ref string message,
ElementSet elements)
{
UIApplication uiapp = commandData1.Application;
UIDocument uidoc = uiapp.ActiveUIDocument;
Application app = uiapp.Application;
Document doc = uidoc.Document;
// Get available Views - Filtered Element Collector
FilteredElementCollector colViewFamilies = new FilteredElementCollector(doc);
colViewFamilies.OfClass(typeof(ViewFamilyType));
// Find 3D View type views
var view3DFamilyTypes = from elem in colViewFamilies
let type = elem as ViewFamilyType
where type.ViewFamily == ViewFamily.ThreeDimensional
select type;
// Modify document within a transaction
using (Transaction tx1 = new Transaction(doc))
{
tx1.Start("CreateView");
// Arrays with the XYZ coordinates of the up and forward vectors for the needed views
XYZ[] positionsUp = new XYZ[3];
positionsUp[0] = new XYZ(0, 0, 1); // Left view
positionsUp[1] = new XYZ(0, 0, 1); // Front view
positionsUp[2] = new XYZ(1, 0, 0); // Top view
XYZ[] positionsForward = new XYZ[3];
positionsForward[0] = new XYZ(1, 0, 0); // Left view
positionsForward[1] = new XYZ(0, 1, 0); // Front view
positionsForward[2] = new XYZ(0, 0, -1); // Top view
// Create new 2D Views of the model with different orientations
for (int i = 0; i < 3; i++)
{
View3D view = View3D.CreateIsometric(doc, view3DFamilyTypes.Last().Id);
XYZ eye = new XYZ(0, 0, 0);
XYZ up = positionsUp[i];
XYZ forward = positionsForward[i];
view.SetOrientation(new ViewOrientation3D(eye, up, forward));
view.DetailLevel = ViewDetailLevel.Fine;
view.Scale = 300;
// Disable Analytical Model category Graphic Override
foreach(Category cat in doc.Settings.Categories)
{
if(cat.CategoryType == CategoryType.AnalyticalModel)
{
if (view.CanCategoryBeHidden(cat.Id))
{
view.SetCategoryHidden(cat.Id, true);
}
}
}
}
tx1.Commit();
}
return Result.Succeeded;
}
}
}
AddViewToSheetCommand.cs (Gets created views and Level 1 (default level), creates viewports and adds them to a sheet):

Viewport viewport4 = Viewport.Create(doc, sheet.Id, level1.Id, new XYZ(1, 0.40, 0));

}
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.
