Ok, so I found a way to get my track into sketchup. First I followed
this tutorial to get the coordinates of my track into a .txt file. Then I downloaded and installed
this extension for sketchup. Then you just import the coordinates into sketchup with the plugin and voila! You still need to make the tubes for the track (if that's what you want) since this method only imports a single spine for the center track 'or' heartline and not the tube spines.
