Offset problems

[Michael Ricci]

Sorry. Same old Autocad problems. I have a simple polygon that I am trying
to offset 600'. I want rounded corners so I try the 'buffer offset' command
but it does not round corners. I created a UCS with my polygon near 0,0.
No change. I offset the polygon only 10' to see if some sharp corners were
causing the problem. No difference.

I change Acad variable offsetgaptype to 1 and then offset. Same result.
Anyone have any idea of my problem?

Thanks,
Mike Ricci
