  Hi ledisnomad,
  
  are you still struggling, or is this one solved?
  The script excerpt looks fine to me - are you sure you don't have any NULLs in your array? Maybe try an array_print to check for that...

  I'm struggling with nested arrays. I'm creating a script that creates an eggcrate structure for laser cutting a surface. I know there are scripts out there I could download, but I'm doing it from scratch to learn.
  
  I have a function called CreateRibs, that ends like this:

                  arrLoft = Rhino.AddLoftSrf(Array(arrContourCrvsV(j),arrProjectedCrvV(0)))
                  ReDim Preserve arrRibsV(i)
                  arrRibsV(i) = arrLoft(0)
          Next
         
          Call Rhino.DeleteObject(strPlanarSrf)
         
          Ribs = Array(arrRibsU, arrRibsV)

  Then I'd like to intersect the objects in arrRibsU with those in arrRibsV. If I use the IntersectBreps method like this:

  Call Rhino.IntersectBreps(Ribs(0)(i),Ribs(1)(j))

  It gives me an error on the InstersectBreps line that a string is required. I thought Ribs(0)(i) would reference the lofted surface from above. What am I missing?
