Can't create wall foundation

[Sydra7]

Sample code:

public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{

try
{
var document = commandData.Application.ActiveUIDocument.Document;

Transaction transaction = new Transaction(document, "Create Footing");
transaction.Start();

var wall = (new FilteredElementCollector(document).OfClass(typeof(Wall))).ToList()[0] as Wall; //I placed a wall with hand!

var foundationType = document.GetElements<ContFootingType>().ToList()[0];

var continuousFooting = document.Create.NewFoundationWall(foundationType, wall);

transaction.Commit();
}

catch
{
return Result.Failed;
}

return Result.Succeeded;
}

Exception:

"A first chance exception of type 'System.Runtime.InteropServices.SEHException' occurred in RevitAPI.dll

Additional information: External component has thrown an exception."

What is wrong with the footing creation?

(I use Revit 2013 API)

Dear David,

I am sorry to inform you that there was an issue with the NewFoundationWall method in Revit 2013.

It has been fixed in Revit 2014.

I found this information searching through my old ADN issues and encountering case 07700489 [Error when creating a new foundation wall] and SPR #230113 [NewFoundationWall does not work] that I explored back in October 2012.

Sorry for the bad news for Revit 2013, and happy to let you know it should work fine in Revit 2014.

Best regards,

Jeremy
