Ajustar a guías ¿qué ha pasado?

Yes, as @Charlie_Faggi7990  mentioned, a Web preset can activate Snap to Pixel and that stays like that (also in new print and other documents) until it is turned off in the View menu.

hola York, fijate cuando entras en archivo nuevo,  elegi cualquier otro que no sea web.

mi problema era que las guias no se ajustaban en una interseccion, siempre me quedaban antes o despues, iba como saltando sin la suavidad que precisas en la precision..saludos! 

Hello @YORX,

Looking forward to hearing from you.
