Hello,

This is indeed unexpected. From what you explain in your email, I don't 
think you did anything wrong, so I suspect there is a bug in the 
package. What version of CGAL do you use? There has been some changes in 
the Shape Detection package lately (but if I remember correctly, nothing 
that addresses a bug like this one).

Is there any way you could you share the point cloud so I can try to 
reproduce it and find where is the bug?

Best,
