Remarks

This method returns direction analysis data for a Surface. Data only exists if it has been generated in the Surface Analysis tab.

 2public void DirectionAnalysis()
 3{
 4    using (Transaction ts = Application.DocumentManager.MdiActiveDocument.Database.TransactionManager.StartTransaction())
 5    {
 6        // Get the first surface in a document           
 7        ObjectId surfaceId = doc.GetSurfaceIds()[0];
 8        TinSurface oTinSurface = surfaceId.GetObject(OpenMode.ForRead) as TinSurface;
 9        foreach (SurfaceAnalysisDirectionData d in oTinSurface.Analysis.GetDirectionData())
10        {
11            editor.WriteMessage("Min dir: {0} Max dir: {1} scheme: {2} \n", d.MinimumDirection, d.MaximumDirection, d.Scheme.ColorName);
