Slice intersection

Hi,
i'm working on a carbonate aquifer and i've the problem with the modeling of the slice because i don't know how i can do to intersect several slice. For example contact between carbonate and marl.

thanks

You can't intersect slices. You can instead put the slices a distance of 0.1m away from each other at your proposed intersection then change the properties of the slices, so they don't continue along for the rest of the "intersection".
