Which build of FME are you using? Even if a 3D feature is clipped by a 2D feature, the clipped features should still have z-values. However, they might not be the correct z-values.
Dmitri created a custom transformer called 3DClipper which uses the SurfaceDraper to get around this problem. You can get it from FMEpedia at http://www.fmepedia.com/index.php/3DClipper, inside of 3DClipper.zip

Hi
as far as i remember, you get a 2d feature from the clipper if the clipper i
2d, so try cheking you clipping polygon to se wether it is 2d or 3d, if it
is 2d just add a zvalue off 0 and you will get 3d features out
