Divide Distance Problem

i wanted to create a hexagon that made of six non-planar equilateral triangles on a surface. i picked a point by evaluating the surface and made a sphere which radius is equals to triangles' edge. Divided the surface by DivDist component(distance equals radius). that should give me six point each of them distanced same and equal. but there was seven points on some regions of surface means a gap between first and last point and on some regions one of the distances is smaller than i want.

i thought it is possible to create by this way geometrically but in practise it didnt occured as i hope.

i found this discussion but i couldnt adapt it mine:

other little problems written on the file. 

Any help would be appreciated.

Thanks to everyone.
