Autodesk Revit API

[#1]

Hi, I am trying to figure out how to place a repeating detail in a model using the API.

I have the Repeating Detail component defined already in my document, so I assume that it is just a matter of finding the right Family Symbol for my repeating component and treating as a line detail component using something like doc.Create.NewFamilyInstance(Line,Family Symbol,View)

but I can't quite figure out how to get it to work.

Any advice would be much apprecieated.

Thanks,

Clayton

Hi Clayton,

If you know the family symbol, it is just as you said, call NewFamilyInstance to generate the family instance.

The code should like: (Note, I didn't add the code to find the target family symbol)

    [Autodesk.Revit.Attributes.Transaction(Autodesk.Revit.Attributes.TransactionMode.Manual)]
    [Autodesk.Revit.Attributes.Journaling(Autodesk.Revit.Attributes.JournalingMode.NoCommandData)]
    public class CreateRepeatDetail : IExternalCommand
    {
      public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
      {
        try
        {
          UIApplication app =  commandData.Application;
          Document doc = app.ActiveUIDocument.Document;

          Transaction trans = new Transaction(doc);
          trans.Start();

          //find the symbol.
          FamilySymbol symbol = null;
          // fine the family symbol here.

          // create the line
          Line line = app.Application.Create.NewLineBound(new XYZ(0, 0, 0), new XYZ(20, 0, 0));

          //Create the instance.
          FamilyInstance instance = doc.Create.NewFamilyInstance(line, symbol, doc.ActiveView);

          trans.Commit();

          return Result.Succeeded;
        }
        catch (Exception ex)
        {
          MessageBox.Show(ex.Message);
          return Result.Failed;
        }
      }
    }

Note: For simplicity, I use doc.ActiveView to get a view. This requires your active view is not a 3D view.

Hope this helps.

If this still cannot make you through, please upload your family, i will finish the command.
