Import a single view template from another file

[DanielKP2Z9V]

Is it possible to import a single view template from a another project file without downloading all the others? The only builtin tool I could find TransferProjectStandars operates on entire categories and not individual types.

No, I used to import all the view template in new project then delete all unwanted view template than import only specific view template to my project

Thanks, I'm writing a script in C# now to export only selected viewtemplates into a new .rvt file, but got stuck.

[DanielKP2Z9V]

As per that linked thread above the script is now finished and seems to work fine exporting only the selected view templates to an empty .rvt file (CustomGUI not included - I'll try to open source the full codebase later)

using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;

namespace scripts
{
    [Transaction(TransactionMode.Manual)]
    public class ExportViewTemplatesToRvt : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            UIApplication uiApp = commandData.Application;
            UIDocument uiDoc = uiApp.ActiveUIDocument;
            Document doc = uiDoc.Document;

            // Get all view templates in the document
            FilteredElementCollector collector = new FilteredElementCollector(doc);
            List<Autodesk.Revit.DB.View> viewTemplates = collector.OfClass(typeof(Autodesk.Revit.DB.View))
                                                        .Cast<Autodesk.Revit.DB.View>()
                                                        .Where(v => v.IsTemplate)
                                                        .ToList();

            List<string> properties = new List<string> { "Title" };

            var selectedViews = CustomGUIs.DataGrid<Autodesk.Revit.DB.View>(viewTemplates, properties);

            if (selectedViews.Count == 0)
                return Result.Cancelled;

            // Prompt user to choose location and file name
            SaveFileDialog saveFileDialog = new SaveFileDialog();
            saveFileDialog.Filter = "Revit File (*.rvt)|*.rvt";
            saveFileDialog.Title = "Save As";
            saveFileDialog.ShowDialog();

            // Check if the user cancelled the operation
            if (saveFileDialog.FileName == "")
                return Result.Cancelled;

            // Create a new Revit document
            var revitApp = uiApp.Application;
            Document newDoc = revitApp.NewProjectDocument(UnitSystem.Metric);

            // Start a transaction
            using (Transaction transaction = new Transaction(newDoc, "Export View Templates"))
            {
                transaction.Start();

                // Copy the selected elements to the new document
                List<ElementId> copiedIds = new List<ElementId>();
                foreach (Autodesk.Revit.DB.View selectedViewTemplate in selectedViews)
                {
                    CopyPasteOptions copyOptions = new CopyPasteOptions();
                    copyOptions.SetDuplicateTypeNamesHandler(new DuplicateTypesHandler());
                    ElementId copiedId = ElementTransformUtils.CopyElements(doc, new List<ElementId> { selectedViewTemplate.Id }, newDoc, Transform.Identity, copyOptions).FirstOrDefault();
                    copiedIds.Add(copiedId);
                }

                // Commit the transaction
                transaction.Commit();
            }

            // Save the new document as .rvt
            string filePath = saveFileDialog.FileName;
            SaveAsOptions saveAsOptions = new SaveAsOptions { OverwriteExistingFile = true };
            newDoc.SaveAs(filePath, saveAsOptions);
            newDoc.Close(false); // Pass false to indicate that changes should not be saved

            return Result.Succeeded;
        }
    }
}

And for the sake of completeness, the equivalent code to import from that temporary .rvt file (my project browser freezes when I have more than one document opened at the same time in a single revit process, so can't use TransferProjectStandards dialog):

using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;

namespace scripts
{
    [Transaction(TransactionMode.Manual)]
    public class ImportViewTemplatesFromRvt : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            UIApplication uiApp = commandData.Application;
            UIDocument uiDoc = uiApp.ActiveUIDocument;
            Document doc = uiDoc.Document;

            // Prompt user to select the .rvt file containing view templates
            OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.Filter = "Revit File (*.rvt)|*.rvt";
            openFileDialog.Title = "Select .rvt File";
            openFileDialog.ShowDialog();

            // Check if the user cancelled the operation
            if (openFileDialog.FileName == "")
                return Result.Cancelled;

            // Open the selected .rvt file
            string filePath = openFileDialog.FileName;
            Document sourceDoc = uiApp.Application.OpenDocumentFile(filePath);

            // Get all view templates from the source document
            FilteredElementCollector collector = new FilteredElementCollector(sourceDoc);
            List<Autodesk.Revit.DB.View> viewTemplates = collector.OfClass(typeof(Autodesk.Revit.DB.View))
                                                        .Cast<Autodesk.Revit.DB.View>()
                                                        .Where(v => v.IsTemplate)
                                                        .ToList();
            
            if (viewTemplates.Count == 0)
            {
                TaskDialog.Show("No View Templates", "The selected .rvt file does not contain any view templates.");
                return Result.Failed;
            }

            // Select view templates to import
            List<string> properties = new List<string> { "Title" };
            var selectedViews = CustomGUIs.DataGrid<Autodesk.Revit.DB.View>(viewTemplates, properties);

            if (selectedViews.Count == 0)
                return Result.Cancelled;

            // Start a transaction to import view templates
            using (Transaction transaction = new Transaction(doc, "Import View Templates"))
            {
                transaction.Start();

                // Copy the selected view templates into the active document
                foreach (Autodesk.Revit.DB.View selectedViewTemplate in selectedViews)
                {
                    CopyPasteOptions copyOptions = new CopyPasteOptions();
                    copyOptions.SetDuplicateTypeNamesHandler(new DuplicateTypesHandler());
                    ElementTransformUtils.CopyElements(sourceDoc, new List<ElementId> { selectedViewTemplate.Id }, doc, Transform.Identity, copyOptions);
                }

                // Commit the transaction
                transaction.Commit();
            }

            // Close the source document
            sourceDoc.Close(false); // Pass false to indicate that changes should not be saved

            return Result.Succeeded;
        }
    }
}

great you can mark this toped as solved, if you already got it works

TransferSingle does a decent job.

Transfer Template is free but only transfers templates.
