Hi,

take a look at this:

http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Kernel_23/Chapter_main.html#Subsection_11.3.1

For calculations between Vectors and Points there are constraints: you 
can do arithmetic between a Vector and a Point, but not between two 
Points, and
you can use CGAL::Origin to convert a Point to a Vector.
