Internally, I convert units on-the-fly. It's just a matter of proliferating a scaling factor throughout the code that checks the current document units before building an object, so that it always converts properly to mm. At the same time, I still assume that units are fixed to the document / project and don't change. Which means my unit-handling code is likely very broken.yorik wrote: ↑Tue Mar 12, 2019 2:08 pmYou have a point there. There is not much sense in enforcing a unit to the user, however indeed it would be a good thing to be informed of the unit the model is intended to be used with. It could also have impact on precision, etc.
It seems to me the best path for that would be to add a field in File -> Project information
Expertise is entirely relative. I would use the term sparingly.
