How would you make an object (lets say a simple beveled curve, with filled caps lol, turned into mesh) that is obviously not as ‘solidy’ into something with real mass?
Solidify sucks, as it only extrudes the edges, as far as I know…
The problem is that our friend here most probably didn’t convert the curve into an object by pressing Alt+C and remove doubles with ‘remove doubles’ command in ‘W’ menu once he was in edit mode of the object.
