Offset curve with corners on surface


When I try to do the offset of this curve on this surface using RhinoOffsetCurveOnSrf, I loose the corners of the curve… if the offset is to inside the curve it’s ok, but if the offset is to outside, it looses the corners.

Any idea to keep the corners after to do the offset?

I add the file

Thanks in advance

Hi Jona,

There is no way to control the corner generation. I’ll add your geometry to a wish list item. Perhaps we can get something added to Rhino 6.
