EP curve dont snap to other curve
 

I have 2 EP curve (3 cubic uniform)
I wnat to add a 3th curve tath snap to this 2,
but this 3th curve dont snap to the left curve, snap also to the right.

I try to reset all settings and preference, but nothing.

Sometimes curves snap to ortogonal axis of grid, but the grid is not visible.

how r u doing it

r u holdin down 'c' and using mouse wheel to snap

also it sometimes depends on ur view

try top, side and front to see it ot works

also im not sure on this but it may be less acxcur when there are less cvs on the curve

yesssss great its number of spans,
I increase span from 4 to 11 and works good

tnx for illumination
