I think that Inventor gets pretty good estimates too. Many of the designs I posted on Delphi have never been built, but my team did use the manually machinable swerve that I posted here before the season. The CAD for that said that It would weigh 6.85 lbs, and the real thing weighed in at 7 lbs even (and the real module had long motor wires on it when we weighed it). So I wouldn't say it's perfect, but it can be pretty close.
