algorithmic modeling for Rhino

get the curve parameter that results from my LinePlane intersection

hi all,

I am wondering how to get the curve parameter that results from my LinePlane intersection.

Actually it returns me d = -1

 

 

my code:

Private Sub RunScript(ByVal plane As Plane, ByVal line As Line, ByRef A As Object) 

Dim d As Double

d = rhino.Geometry.Intersect.Intersection.LinePlane(line, plane, doc.ModelAbsoluteTolerance)    


End Sub

 

thanks for your help

well I should precise my question:

I know that I should get my intersection point using the following code

line.pointAt(d)

but which is weird is that d=-1 and my plane and point intersect...so it should be d= something between 0 and 1

any suggestions ?
