I have 3Ds Max 7. I have tools for City Life that work with 3Ds Max 7 and have found hints that it is possible to convert models from City Life to Cities XL Platinum. I have the Highway standards from Different US Department of Transportation websites to use for designing new Highways. Someone please help me find the info I need. I have modeled in Trainz 2009 a modular roundhouse MNW roundhouse. I have also modeled new vendor buildings and aesthetics for RollerCoaster Tycoon 3 which I will post by 12/01/2014 under the name A2Custom.
