Re: Add Revit Links to Project with C#

Hi  , thank you for your reply!

Yeah it was looking odd to me as well, but I fount it in the example code in the Revit API Docs website and I took it as it was...I guess they were probably showing three different possibilities?
from Revit API Doc

Anyways, I deleted that part (latest code copied below) but it is still not working...again, it starts calculating and it gives the progress bar saying it is doing something with that file but then nothing happens. What am I doing wrong??

        public Result Execute(
          ExternalCommandData commandData,
          ref string message,
          ElementSet elements)
        {
            // Get application and document objects

            UIApplication uiapp = commandData.Application;
            UIDocument uidoc = uiapp.ActiveUIDocument;
            Autodesk.Revit.ApplicationServices.Application app = uiapp.Application;
            Autodesk.Revit.DB.Document doc = uidoc.Document;

            try
            {
                using (Transaction transaction = new Transaction(doc))
                {
                    transaction.Start("Link files");

                    string testFile = @"C:\Users\atassera\AT\C#\Revit\LinkRVT_test\Utilities\AR-GAM-3DM-FACADE-RVT.rvt";

                    ModelPath linkpath = ModelPathUtils.ConvertUserVisiblePathToModelPath(testFile);

                    RevitLinkOptions options = new RevitLinkOptions(false);

                    RevitLinkLoadResult result = RevitLinkType.Create(doc, linkpath, options);

                    RevitLinkInstance.Create(doc, result.ElementId);

                    transaction.Commit();
                    return Result.Succeeded;
                }
            }

            catch (Autodesk.Revit.Exceptions.OperationCanceledException)
            {
// If user decided to cancel the operation return Result.Canceled

                return Result.Cancelled;
            }

            catch (Exception ex)
            {
// If something went wrong return Result.Failed

                Console.WriteLine("There was a problem!");
                Console.WriteLine(ex.Message);
                return Result.Failed;
            }
        }
    }
}

 I actually have two catch clauses (more as place holders at the moment) but I thought they didn't really make a difference and I didn't copy them here as they would have made the code longer...I copied them now for clarity.

Thanks guys, any suggestion and clarification is very well appreciated!

Cheers,

Andrea
