Thanks for a heads-up! Error is fixed in version 3.2.3
Great add-on, I've been waiting for parametric objects for what seems like forever. It would be nice to also see ND curves such as spirals, stars, and other shapes. Maybe with all the options we have with blender curves as far as bevels and extrusions?
There seems to be an issue with 'instance copy' with Blender 5?
