Hey, I built a little map, something like viaduct. Still not completed, have few ramps to add. But when importing object in beamng drive, most of the time there is a problem with collision, you can go through objects, than collide with empty air. Collision works 1 in 10-20 times when importing something. This time it worked
great idea! i'll move object so the edge of it is in coord start, make sure there is no part of object in negative coordinates in sketchup before exporting and check if it would work. BMW, I'll be glad to share, just to add few more things to it.
