gmod sketchup

I have completely no idea where to post this, so sorry if this is the wrong place :s

Well I usecsketchup and made a bunch of things with it already and now I want these 3d models into gmod.
Like props…
Any tutorials how to do it in sketchup and get it in gmod?

seriously why does everyone post modeling shit in SCRIPTING. its not that hard, theres a forum that says MODELING.
