Offset fail

I extracted a number of contours from a brep and am trying to offset those curves .25".  When I set the offset distance to .25" a couple curves fail, when I offset it .32" it starts working again.  Any idea what's going on or maybe a cleaner way to offset to prevent this problem?

      Anyone have any ideas? I can't offset a set of curves without some of them failing and it's driving me crazy!

        Hello, i have a question about offsets in grasshopper. In this example i am doing an offset in grasshopper with a closed curve and it fails. Then i do the same offset in rhino with the same curve and it works perfectly.

        Anyone knows why this could happen?
