   jeremy,
   i am working on a facade design project and my facade geometry is driven by the ecotect analysis data, based on that data my facade panel parameters change, I am using divided surface tool to tessellate the panels on surface of the building, since my building surface is based on double curve i am having a lot of difficulty in populating my panels, its weird but sometimes it fails giving me the error saying “Not a Rect2DTilePattern”, Is there a work around for this? My code is based on one of your massing examples,
   private void assignDistParam(double[] excelOrientArray)
   {
   List dsList = GetElements();
   foreach (DividedSurface ds in dsList)
   // here, ds is the panel which needs the distance parameter changed according to the values from array, to control the aperture of it.
   {
   GridNode gn = new GridNode();
   int uCount = ds.NumberOfUGridlines;
   int vCount = ds.NumberOfVGridlines;
   int u = (uCount – 3);
   while (u > 0)
   {
   gn.UIndex = u;
   int v = 0;
   while (v 0))
   {
   int i;
   double paramValue;
   i = (((vCount – 3) * (u – 1)) + v);
   //correspond with excel data array
   double angleHolder = excelOrientArray[i – 1];
   int lowbound = 155;
   int upperbound = 205;
   double R1;
   double R2;
   double R3;
   double R4;
   if (lowbound <= angleHolder & angleHolder < upperbound)
   {
   R1 = (angleHolder – 180);
   if (R1 != 0)
   {
   R2 = (180 / R1);
   R3 = (90 / R2);
   if (R1 < 0)
   {
   R4 = (90 + R3);
   }
   else
   {
   R4 = (90 – R3);
   }
   param.Set(R4);
   }
   else
   {
   param.Set(R1);
   }
   }
   else
   {
   paramValue = 30;
   param.Set(paramValue);
   }
   }
   else
   {
   }
   }
   }
   }
   v = v + 1;
   }
   u = u – 1;
   }
   }
   }

   Jeremy,
   seems like some parts of the code is missing in my previous comment,so i am posting it again,
   private void assignDistParam(double[] excelOrientArray)
   {
   List dsList = GetElements();
   foreach (DividedSurface ds in dsList)
   // this part of the code reads the analysis values from the array and assings them to parameters those which are matching the criteria.
   {
   GridNode gn = new GridNode();
   int uCount = ds.NumberOfUGridlines;
   int vCount = ds.NumberOfVGridlines;
   int u = (uCount – 3);
   while (u > 0)
   {
   gn.UIndex = u;
   int v = 0;
   while (v 0))
   {
   int i;
   double paramValue;
   i = (((vCount – 3) * (u – 1)) + v);
   double angleHolder = excelOrientArray[i – 1];
   int lowbound = 155;
   int upperbound = 205;
   double R1;
   double R2;
   double R3;
   double R4;
   // panels which meet this criteria will update the parameters..
   if (lowbound GetElements() where T : Autodesk.Revit.Element
   {
   List elements = new List();
   ElementIterator eit = m_doc.get_Elements(typeof(T));
   eit.Reset();
   while (eit.MoveNext())
   {
   T element = eit.Current as T;
   if (element != null)
   {
   elements.Add(element);
   }
   }
   return elements;
   }
   }
   }

   Dear Adi,
   Sorry for the late response. As you may have seen, I am travelling right now and will continue doing so for the rest of the year, so I have not been able to look into your issue. By the way, I searched my samples globally for the string ‘assignDistParam’ but cannot find it, so I do not know what sample you are referring to. I hope that you have been able to make some progress in spite of my lack of response.
   Cheers, Jeremy.
