Hmmmm. Two possible theories:

- Do you have flipped normals in AC3D? Perhaps the surfaces are there but not visible if 1-sided surfaces are on.

- Or--and this is more likely--do you have any polylines in your AC3D model? Some of the exporters will treat polylines as polys on export.

To fix, try selecting everything and clicking the "poly" button under "surface type" in the lower left hand corner just above the materials palette.

Also, make sure the model is optimized first before you export. I usually highlight all the vertices in each object and "snap together by distance" by a very small amount (.001), then I click Object > Optimize Vertices and Object > Optimize Surfaces. This gets rid of any coplanar or degenerate surfaces.
