How to decrease size when exporting contours

Right now i have a huge problem. I have made a surface from a pointclud (ground) and made contorus on that 0,5m apart. When i am trying to export only the contours in a dwg it is 160(!)MB. I tried project cleanup without result, i gave all of the lines the height "?" so the 3D wouldnt be a problem and the it got down to 130mb. How could i do this? it should not be any bigger than a couple of kb i think, its only lines. The projectfile is here and i think that the surface and contours should be in there even that the project library is missing. 

Any one knows how to do this?
