help in getting coordinates via listing

[bionicakoh]

hello! I have created a circle from 3topo points. Im having difficulty getting accurate elevation (z)  of the center of circle (pile representation) via cad polyline listing. im getting same "z" all through out which in fact is not. I have 500 topo points and will take time if get it one-by-one. Can please anyone explain me the reason behind and please suggest other method of getting its elevation efficiently? thanks!

DATAEXTRACTION probably will get it for you but it will not tell you what point come from where.

Attach your .DWG  here, let's see why would the Z be different ?

Not sure if this is what your trying to do here?

Normal Polyline's inherit the original point elevation snapped to. This elevation remains constant no matter what the point elevations are after first point snap

Assuming the actual Points snapped to are different, try using the 3DPOLY command instead, a 3d polyline will assume the actual elevation snapped at each point.
Now you should see differing Z coordinates.
