2D Section extracted from Layercake

Hi all,

I have a layercake with different horizons which are available as grids. 
I would like to extract a 2D section (where I define two points) from 
the cake where the horizons from the layercake will be projected on. Is 
that possible with a straight forward method in GMT?

I did on my own extracting points from the grid with grdtrack and 
plotted polygons with psxy. However I had to deal with topology 
problems. The layercake consists of top layers, so I had to take care by 
hand which is the base of the layer to define the complete polygon. This 
has quite unhandy and not easy to adapt for new geometries. So, I'm 
looking for something easier. I'm also happy about ideas to make this an 
easy task, if GMT can't do it. :)

best regards

Nils
