How do I scale a track?

[vandyne06066]

I want scale my entire model... tracks, terrain, cones, trees ... everything. Now I know better but I created my track too small. I hope I can double it without having to redo everything. I can deal with scaling the non-track objects back down after but not the terrain and tracks. Any help would be appreciated. Steve

very easily: you click on "move node and control points" and go to resize. there you can enter the right length in meters.
