Mesh coarse approximation

Does anyone know how Daniel Piker is doing the quad mesh approximation shown in response to the above thread?

Try this plugin.

I just downloaded earlier today but any mesh I feed it, even a simple box, returns no results. this is what shows up in the command line:
Command: CreateQuadMesh
Select Objects to Export
Select Objects to Export. Press Enter when done
Creating mesh…
Reading mesh…
No objects added to selection.

Working fine for me. Contact the developer if you want…

Never mind! turns out the output mesh is always on the the default layer which I had off… thanks for that though.
