>>Some objects created in AME with bool' will not smooth at all, but even in 3ds, objects surfrev'ed and then bool'd can have faces that will not smooth whatever you do. Are you uniforming normals on conversion of solid models? This is usually not the correct choice for solid models – they have correct normals, and results from Boolean operations can confuse the "auto" normal facing. Examine your meshes carefuly that need to smooth. Ensure that vertices match at the transitions and that they are a contiguous mesh. Remember, smoothing can only occur across welded vertices. If AutoSmooth still isn't working, bite the bullet and assign smoothing groups yourself. You'll find you can assign FAR fewer than Autosmooth does (making them valuable for selection purposes later) and you can decide what constitutes an edge or not – you're not constrained by a universal angle that may not be appropriate across the entire mesh. Good luck, – Phil
