I’d like a built in tool for making sure hollow models have a drainage hole. Let’s call this a “poke tool” for the sake of simplicity. I’m currently doing this outside Preform for my models, but it would be nice to have a simple one inside PreForm, in case a sent .stl from a 3rd party does not have a hole for hollow models. It would streamline workflow and negate print errors caused by this (i.e. operators forget to do it). Detection of hollow cavities would also be nice. Thanks for listening.
