Superflatten Autocad 2023

Hi! I am trying to superflatten my AutoCAD file that has xrefs, blocks, and regular lines. After running SuperFlatten command it gives me this message and nothing gets flattened--I still have lines on z-value. Why is it not working? I downloaded SuperFlatten 1.1a.lsp file but when I use it nothing happens. If someone can provide solution, would be much appreciated.Nothing flattens

have you tried running the lisp function on a dwg with only a few objects to make sure it works on that first before running it on a more complex dwg?

Yes, I checked it and it works on other files. Also this particular file works when I select certain clusters of lines but not when I select everything.

So the current version is 2.0c.

I wouldn't recommend using the one at the link you posted that exports and imports WMF's which loses more than elevation.

Stick to the original author Joe Burke's 2.0c version updated on the first page.
