How do you fill in polygons in 3D Space

For my job here I have a contoured map of a sand structure. I have converted that entire 2D map into a 3D map. Showing the elevation of the contours relative to the surface. I need to know how you can hatch or fill in with color the 3d polygons that are shaping the subsurface. When i try to hatch it, it works but it just pastes it at the surface at Z:0 and even if i bring that hatch down it won't form to the multidemnsional polygon that i am trying to cover. Can anyone help me? Here is a pic of what I am trying to do. 


The geen/blue is the fault plane i have been able to plot as well as shade in using 3D Face, but the problem I run into for the RED contour lines is that they are arcs and when i use 3D Face it doesn't allow it to bend to conform with the arc shape.

Try the _LOFT command between the contours.

It won't be good-looking as a true Civil surface, but better than the.. rubbish you posted, sir.
