I think Cutlist Plus is well regarded in terms of those functions; it would be worth a look. The only rendering software I’ve played with is one called Twilight, which one of our other customers uses. All of the rendering software is very involved and I just haven’t had time to master it. They have a free version and a paid version; I’ve just played with the free one. I got it to render, but haven’t yet got the hang of doing the proper lighting and material setup.
