I every body. I recently bought Trainz 2012 and like surveyor section. So, 1) Why grid in real scale are 720 x720 instead of 1000 x1000, would it not be easyer for constructor. 2) Is there some draw lines that take less memory than tools menu. 3) Is there some fan living in my erea .4) What is the software they use to create 3D objects. 5) I create few routes and I lost ererything when I try to install SP1 49922 to 57720. Is there somebody who can tell me in wich folder I could find my files. Everything goes bad since I have tried to instal that patch. So is there a way find the hard work I have losted. At least if I could fend my files I would be able to continue with my build version 49922. SOS Regards Guy
