GeomAPI_ProjectPointOnSurf::NbPoints ... gives the same orthogonal projection several times

David B.'s picture
Forums: 

Hi,

i receive the uv parameters for an usurface with GeomAPI_ProjectPointOnSurf. My surface is 2d, i mean z=0, when i project a gp_pnt (with z=0, and without z=0) on my surface, normally it should return just one result, cause z=0... but i get many points when i check ::NbPoints(), and all points seems to be the same, the uv are the same.

What is the reason?

thanks in advance.

David B.
