Who knows if it’ll work yet, but whilst trying to support a large, flat, thin surface for printing, I found that the slicing software didn’t really seem to ‘get it’
So, I tricked it a little by adding the seeds for supports inside Fusion360
Essentially this is just creating a grid of ‘support tips’ and merging them with the wanted body.
The slicer software sees these tiny sticky-outy bits and has no choice other than to add supports to them
alternatley, they can serve as a grid for you to add some manual ‘heavy duty’ supports and surround with more medium duty ones
This is a large flat lower part of a case.

By adding an easy ‘pattern’ of 0.5mm high by 0.1mm diameter zits, I trick Lychee into supporting those areas.
The End result – Evenly spaced ‘starter’ supports that can be manually supplemented. This ensures that no points of the model will be droopy.
I’ve started with a grid around 10x10mm. no reason why this grid can’t be a bit smaller, just some experimenting needed
