Can I automatically generate contour lines from a 3D ground (Mesh) with V8i?

Hi everybody!

Does anybody know if there is a way to automatically generate contour lines froma a 3D Mesh? Would be perfect to get automatically the lines and the altitude text.

I have a 3D model of all the region's territory (precise and with the correct altitude) and I use it really often, but until now if I needed contour lines I generated an horizontal section each meter...defenitely too much time wasted.

I know other programs have such a method but I can not find anything like that in Microstation.

Hope somebody can help! Thanks
