Hi.
I was working on a presentation model of a quite big building. I was actually finished, with windows and everything. Then today, I wanted to add some other facadesolutions. Apparently the 3D model at some point got too heavy for the program or something - at least it crashed. When I opened the model again, it ask me if I want to save the backup as a new position. I said no, because it is my experience that there is normally nothing new in these backup positions. But I found that 7th floor had dissapeared, but I thought, ok there is not so much work in 7th floor. But then quite some time later, when I was finished with 7th floor I realizes that all the windows and doors had dissapeared in all floors....
Is it possible to recreate the model, as it was earlier - or is it too late now? I have checked my external HDD for a backup from yesterday, but found that my backup looks like it is not doing correct. It should take a backup every day - I thought I had set it up to do that - but it looks like not....
