biarc component behavior is uncany.
in the following input, inputs are the results of a factor with value "0.43...", it is working.

biarc is OK.gh (92.1 KB)

when the value is slightly changed, for instance to "0.36...", biarc is not working anymore. However, it should be working (a construct of the biarc is done without the biarc component).

I apologize in advance for the behavior setting is complex. For the record, I was unable to reproduce the problem with simple inputs (see below).
