Generate Points with elevation from 3D polygons

Hi all,

I was hoping someone could hep me with a desperate attempt to use some 3d polygon data I have. I cannot import the 3d polygons into the GIS program MapInfo as it cannot handle 3d polygons.

What I need to somehow do is generate a few points along each of the polylines that will retain that elevation as an attribute.

Is this possible? And if so how is it done?

Thanks a million

Alan
