Exception in modelDecorator.chord

We are using pyCGM2 inside Nexus 2.12 with great results, but we observed an issue as follows;

This appears to be happening if THI and TIB are too close to KNE and ANK (respectively).

Is that an issue, or is there a workaround?

Best regards.

Thanks for your feedback. i alter the implementation of the chord function in version 4.0+ of pyCGM2. that will fix you issue for sure because there is no more iteration.

pyCGM2 4.0 is unfortunatly not embeded in Nexus. You need to install it. check out the website. I explain/illustrate how to install and use executable code.

feel free to contact me for any question.

Best regards.
