Maybe, but the off-level is so small, any differences are completely negligible.
Here’s my redrawing, using the method I described. A few lines missed the plane initially and even when I got them all drawn and on-plane, the top face didn’t form until I drew a line across the middle (redrawing an edge didn’t work).
After that a pushpull down 2ft, then moving edges in the bottom face ‘on red’ locked axis inference, to line up with the bevelled edges in the original. And finally, a move down to the original floor level.

PS. I tried using the Text Tool to label the coordinates of the corners. But often, even though I had a clear inference on an endpoint at the corner, the tool only placed Enter text in the label.
I checked with the Query Tool, and all the corners seem to be dead on a whole-foot height.
PPS. I wasn’t timing it, but looking at the difference in time between my last two posts, it took about half an hour to redraw.
I see I made two mistakes in the version posted here. I missed an outdent and a glass railing on one edge. But the principle worked.
