Hi John,

Please could I ask your help with another issue. When I am plotting this file with the autocad monochrome.cbt some layers still appear in colour. I see that the thing to do might be to convert to .sbt however the convertpstyle command is not available in autocad for mac (which I am using).

I see that the next thing to do is open a new drawing with a .sbt setting. How can I do that? I have found out that for a .cbt you can open an autocad preset .dwt but what do I do for a .sbt setting?

Thanks,
