I recently began using aced 2005 and can't seem to achieve acceptable arc smoothness when rendering. VIEWRES and FACETRES do not appear to make any difference (I've taken both to the max). I'm getting the same results with FACETRES at 0.5 and at 10. I've searched aced help and those two variables are the only ones that are mentioned. Adjusting those made a difference in R2k but seem to have little effect in 2005. Pete
