Hi all, Can anyone please help me solve this error im encountering exporting my London street track. I'm trying to export it into a Racer file to post process it for Cruden. When i select to export the track im hit with an error message which says "Length cannot be less than zero. Parameter Name: Length" . My track contains many sketchup models like buildings, bridges, etc. as it is a city circuit and multiple open tracks to represent connecting streets. I tried couple of things like deleting background image, deleting large objects like building models and any other models but nothing has helped so far. Any help or support is much appreciated. Cheers!
