Smooth result from importing 3d max file?

[pts]

hey everyone, im relatively new to sketch up, im importing a file from 3d max as a 3ds. my problem is i have the faces smoothed out in 3d max with the smoothing groups, but it doesnt look like either the 3ds file or sketchup is reading that so i get a unsmoothed result.

anyone know how to fix this?
