Incorrect Wall Side Info of Wall Sweep

[Anonymous]

I manually create 2 wall sweep both side of wall in Revit. Ideally one wall sweep should have Interior wall side and other should have exterior wall side.
But When I get this WallSide information from WallSweepInfo of WallSweep using APIs.

wallSweep.GetWallSweepInfo().WallSide

It always give us WallSide as Exterior.

I used below code to get all Interior Side wall WallSweeps and it gives zero result.

var doc = commandData.Application.ActiveUIDocument.Document;

var collector = new FilteredElementCollector(doc).OfClass(typeof(WallSweep)).ToElements();
var allInteriorSideWallSweep = collector.Cast<WallSweep>()
                   .Where(wallSweep => wallSweep.GetWallSweepInfo().WallSide == WallSide.Interior).ToList();

TaskDialog.Show("Number of Interior wall side Wall Sweeps : ", allInteriorSideWallSweep.Count.ToString());

Is there any way to get correct wall side information from WallSweep info?

Dear Ankit Bhargava,

I am sorry to say I can reproduce this issue and I failed to find safe way to find interior wallsweep either.
I suggest to refer to following pages on similar question about exterior and interior sides of wall

I was also looking into this. Not sure if this will help but I noticed that when I used the Wall: Sweep (Architecture > Build > Wall > Wall: Sweep), all the created wall sweep are located at WallSide.Exterior.

But when I attached the wall sweep in wall profile, the sweep are correctly placed.
