I think the problem to render that drawing is not the size of the File,  it could be that the drawing is too close, try to zoom in the drawing in the viewport, and then render it, see what happen.

There is normally only one solution here - hardware upgrade.  Generally if your file is this big, you have a lot of detail, stuff like fillets, chamfers, bolts, nuts, washers, etc.  You have to decide which of these you want to show and which can be dumped.  The more surface there are, the bigger the file, the longer the crunch time for a render.....the more performance is required from your pc.  I use a 4 gig ram machine, 256 mb Nvidia graphics card, 2.8 ghz cpu, and on a  file 50mb and larger it still takes a long time to render.
 
Also things like surface textures, lighting and materials make the render heavier.
