I wholeheartedly endorse adding support options to S3D. Supports are an incredibly important part of 3d printing, and unlike a previous poster, I don't believe copying a good idea is bad.
This is a bump to get this visible for V5 - I'd like tree supports in V5. I know this is hard with it's new support stuff, but it could just generate the tree support and treat it as if it was an imported 3d mesh.
Although S3D is a great program, the suppprt structures are second rate, I would have expected to see some type of tree supports in V5 after 3 years waiting, not one that you need to draw up in a seperate cad program. Please pick up you act as we pay for a great program that is still better than other slicers.
