you can de couple the piece of track from the terrain (grounded option & cut terrain) and that can be the bridge section of road. of course you would then need to build the bridge structure. which can also be made in rtb from the walls tool.
thanks for the reply. i created a track on sketchup and added it to an xpack. i selected drivable on Xpack and then Drivable again on RTB but my car goes pass it like a ghost :/ damn,i will try to see that cut terrain option.
I think that "driveable" option is a left over from bobs track builder and or an rfactor export setting..... which wont work for AC. . that section needs to be named properly to be driven on. something like 1ROAD_01 etc etc.
