for me it's working, if you start _LIST and select one of those objects what Z-values do you get? (or upload the drawing with one or two of the objects you tried).

I tried this Lisp but the Z values are displayed as 0
Perhaps your contours are flattened to ground zero, typical behaviour of digitized topo maps.
When I type _LIST I can see all the vertex values(Geomentry X,Y,Z). Why is not showing when I apply the lisp?
I include the polylines (any really) I am trying to have Z values visible on my plan.
your drawing has proxy objects and so that tool reports 0 (why ever, I've not looked into the LISP).
You see that this drawing is not clean if you try to use copy/paste to get those polylines to a new drawing. I get then a message that this is not possible because of proxy-objects.
If you create a new drawing, then insert that drawing you have uploaded into the new one (with option "explode") then this tool is able to write the Z-values to the polylines vertizes.
Good luck, - alfred -
