Prosteel is a marginal product of Bentley. Although the autocad version, the so-called annual update, is actually a new version, many software problems have not been improved after several updates, and some new functions have not been tested. It has no practical significance. If tekla is fully automatic, prosteel is at most semi-automatic, which can complete tekla's work (of course, tekla is not perfect), but it needs more personal settings and adjustments. Of course, the price of prosteel is quite different from that of tekla. You get what you pay for. Personally, the most unbearable thing is that prosteel has been updated for more than ten years. There is no fundamental change between the current version of autocad updated by ss6+ and the version in 1990s, but tekla has changed greatly in recent 5-7 years. Prosteel is still prostructural. If benley just wants to earn some money for software training and maintain software operation, prosteel will not change much in the next ten or twenty years.
