Dear Reader,
question from a Blender Newby.
i am trying to add a custom property to an own mesh plugin.
in order to not have to build two plugins for each shape, it would be nice to know how i add a Boolean or more preferably a ListSelect property to the plugin so i can switch between multiple sizes: radius / edge length / unit
any help is welcome…
thank you
