When I use Trace with “Offset 0” everything works as expected. But when I try to offset the loop it does not work: In this case I would like to enlarge the size of the pocket by 0.2mm but I get way more. What am I doing wrong?

the answer is in the tool tip. 0 causes trace to use the tool radius. when you use any value other than 0, it’s taken as an absolute value, not added to or removed from the tool radius. so to achieve what you’re looking for, add 0.2 to the tool radius.
tbd, I don’t recall the exact reason for this editorial choice. it was years ago.
OK and thank you for your reply.
