Enlarge 3 D view and Printout?

[christopher12]

I am designing a butlers pantry (5 X 5 triangular with 2 access doors) becuase it is a small space the 3d printout is really pretty useless but would be great to see as there are many details my construction guys need to visualize. Any way to make a larger 3d view print (I tried pdf and then printing large but many of the surfaces blend into eachother and picture the same thing. Suggestions would be se appreciated...

Create bigger images at quality 3 or 4 with Create photo dialog box. Surfaces close to each other won't blend.
