Rhinoscript Bug (SR6) – LineLineIntersection

Dim arrLineA, arrLineB, arrPoint

arrLineA = Array(Array(0,0,0), Array(3,0,0))

arrLineB = Array(Array(0,1,0), Array(3,0.99,0))

arrPoint = Rhino.LineLineIntersection(arrLineA, arrLineB)

If IsArray(arrPoint) Then

  Rhino.AddPoint arrPoint

Else
  Rhino.Print "no intersection"
End If

‘this should add point at (300,0,0), but arrPoint is NULL (no intersection)

sometimes my script doesn’t work with certain input, then I try to debug my script

looking for anything I missed..

it takes longer too, as the script gets longer.

This time, it turned out ‘LineLineIntersection’ method was not working properly.
