Line intersect with block

Hi All,

I find the intersected point of Line and block as this code:

'bref is a block reference
Dim tmpLine As New Line(pt1, bref.Position)
Dim ptCol As New Point3dCollection
bref.IntersectWith(tmpLine, Intersect.OnBothOperands, ptCol, 0, 0) 
Dim acLine As New Line(pt1,ptCol(0))

 But the intersected point is not located on block as picture below. I don't know what happen.

Thank you for any help.

Easiest way is explode BlockRerence (method BlockReference.Explode but without adding entities to Database) and then intersect your's line with every entity in collection of exploded entities (maybe recursive if entity in collection is also BlockReference).
