I have been using BobCad V 20 for many years, my computer crashed and I lost it all. Got in touch with BobCad but 20 is no longer supported, the new 30 looks like the old 2007, did not like that one either. Question is are there any programs out there that come close to the older versions of BobCad 17 18 or 20. Any information greatly appreciated as right now I am up the well known creek.
