You and I both want to use ETABS 2013 and gain access to the faster analysis times and new features. But we haven’t made the plunge, at least in part because we might lose work if we get a week or three down the road and realize that we need to revert to ETABS 9.
Good news: now you can downgrade your file! That is, I can downgrade your file. The tool is not ready release to the world, but I have tested it and am confident that it works to take any ETABS 2013 model and push it back to ETABS 9, with no loss of model data (except for any new features unavailable in the older version, of course).
If you’re interested, send me an email at drp181 [a t] gmail dot com. I can do the first few models for free, but if there’s much interest I may ask for a pittance (to help prioritize ‘real’ requests, mainly).
What other roadblocks are there to you using ETABS 2013? Leave a comment and let me know.
