With some geometries, S3D wastes a lot of material on rafts.
For example, when I want to print a large, thin ring, S3D will currently build a larger, FILLED disc as a raft.
Therefore, I propose an option to allow rafts with holes and discontinuous rafts in order to save filament and printing time in some cases.

I would like to know the answer as well.

Version 4.0 includes a completely new raft design that only places the raft where it is actually needed. For example, for the large thin ring you mentioned, this would allow the raft to have a hole in the middle so that it uses much less material.

There are several other new raft options as well, so you can view all of these things on the Additions tab of your process settings.
