Hi,
just wondering if someone can help me out here. Ive been given some Contour lines of a site im working on. Im using the Terrain Compound thingy.
Only problem is my client wants it done layered, if i click layered solid in the parameters i get a coplanar surface at the lowest point.
any ideas on how to fix this? Or is there a better way of doing it?
try to increase the secondary rays bias to 0.01
maybe this helps…
best regards

make a new outer line that is lower?
secondary rays bias at 0.001 fix’s it but for some reason i lose the bottom contour (gets covered with the contour above it) :?
@RErender, i tried adding another contour line lower and smaller than the first one, all this did was to make the coplanar area smaller.
Is this what you mean?
Thanks for the suggestions guys.
I mean to trace a spine around the outside of the entire topo and pull it down bellow the lowest exist’g level. Another option would be to delet the faces that are coplanar and not needed, it is probably part of that weird face at mid right
Bingo 
Thanks Eric ,that fixed it.
