Hey Nathaniel,

I haven't been able to successfully use the truss plugin since date of purchase, as I consistantly get an error that dumps geometry at the Model Axis.  Doesn't matter if it is in a bloated model, empty model, SU2021 or 2022, or which of my machines I am using. Last attempt was on v 3.1.5  I've attached Ruby Console information below. Hopefully this is helpful to you and to anyone else having a similar problem.
