Newb conceptual help - zeroing object surface to the xz grid

[Cadlet]

You need to set the bottom of the coin as the pivot point:
Use snapping to component
enable Pivot mode and let transform gadget snap to the bottom mid point of the coin
call Tools->Coord System and hit "Burn Pivot Point" to make it permanent
Call the transform tool; you can now see where the bottom point is at the Y field
paste in "0.0932" at the Y entry field and you´re set.

Oh, maybe dragging the transform gadget by its center has something to do with letting it snap. Sorry about that. Still not sure about transform object snapping, maybe I need to try some different raster widths. Thanks!

What might get in the way of burning the pivot point (beep - alert when button clicked). Does the object have to be editable?

No, can you check for redundant vertices/points or use Optimize tool to get rid of any not connected points and see if Coord-System tool will work then?
