Hi @PankajKumarDas

Map Tools > Contours > Contour
Use Exact Levels and set Interval level 1 to Zero.

I am doing Tilt derivative map.How to get +45 degree and -45 degree contour and depth from it?

Hey pankaj,if you draw a contours for tilt derivative map it gives the -1 to +1 contour interval only.Tilt derivative means inverese tan(Vertical derivative/Horizontal derviavtive),it menas if the both derivatives give same value i.e vertical /horizontal=1 then inverse tan(1)=45,so -1 and +1 contour itself a -45 degree and +45 degree.
