041 * Defining the surface geometry of the iso geometry model. a surface is made of 1..n surface patches. for convention it
042 * is defined that Surface is a closed geometry. that means each surface patch a surface is made of must touch at least
043 * one other surface patch if a surface is made of more then one surface patch
