Can't export drawing as dwg or dxf

I am trying to export a 3D drawing as .dwg or .dxf but the only two options i get are .dae and .kmz

I have followed the process on this website on how to export a sketchup drawing to CAD, the only problem is those are the only two options in the dropdown available to me.

Your profile indicates you’re using SketchUp Make and also the free web version
DWG and DXF import/export are SketchUp Pro only features.

Ah! thanks, 30 day free trial it is!
