Offset Surface problem

As this is a fairly simple object, is there something to keep in mind to succeed mostly with the OffsetSrf command in V7?

Thank you!

not for OffsetSrf, specifically when you have surfaces meeting at different angles like in your example above.

Super understand. thank you!

But I thing the whole command could be maybe rewritten with an option to turn on to lower precision. I think I would choose this for the sake of OffsetSrf working solidly.
