Offsetting multiple closed curves, one misbehaves

[will_templeman]

Hi, I’m trying to offset these three closed curves but for some reason one of them produces a ‘spike’ towards the origin. I cant work out why, any ideas welcome, thanks

it will not be possible to help you from a screenshot.

please post a minimal grasshopper file that allow s to reproduce the error.
please internalize all geometry.
please include the step with the intersecting Brep s (Brep|Brep)

my guess: the Breps have some defects / resulting in bad curves / wanky curves that do the offset error … but just guessing from a screenshot.

kind regards -tom

Many thanks Tom!

please internalize the geometry at the start of your definition:
(right mouse on component … internalize data..)
